We look at the division of 38615259 by 420 
We want to figure out the number of times 38615259 can be divided by 420.

Step 1:
The number 420 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 420

Going ahead to step 2:
38 divided by 420 is 0 with a remainder of 38.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 38, we get 38.
Bring next digit (6) of the dividend behind the 38 and repeat the process: 386 / 420

Going ahead to step 3:
When dividing 386 by 420, we get 0 with a remainder of 386.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 386 leaves us with 386.
Grab the next digit (1) from the dividend, add it to 386, then carry on: 3861 / 420

Let's proceed to step 4:
If we divide 3861 by 420, we get 9 and a remainder of 81.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we take 3780 away from 3861, we end up with 81.
Grab the next digit (5) from the dividend, add it to 81, then carry on: 815 / 420

Advancing to step 5:
815 divided by 420 is 1 with a remainder of 395.
The next digit of our result is 1. 
Result so far: 91.0
If we take 420 away from 815, we end up with 395.
Take the next digit (2) from the dividend and append it to 395, then repeat: 3952 / 420

Moving on to step 6:
420 can be fit into 3952 9 times, resulting in a remainder of 172.
Record the quotient 9 as the next digit in the result. 
Result so far: 919.0
Subtracting 3780 from 3952 leaves us with 172.
Grab the next digit (5) from the dividend, add it to 172, then carry on: 1725 / 420

Moving on to step 7:
If we divide 1725 by 420, we get 4 and a remainder of 45.
Put 4 as the next digit of the answer. 
Result so far: 9194.0
Subtracting 1680 from 1725 leaves us with 45.
Fetch the next digit (9) from the dividend, attach it to 45 and continue: 459 / 420

Moving on to step 8:
420 goes into 459 1 times with a remainder of 39.
Put 1 as the next digit of the answer. 
Result so far: 91941.0
Deduct 420 from 459 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 9:
420 can be fit into 390 0 times, resulting in a remainder of 390.
The number 0 becomes the next digit in our result. 
Result so far: 91941.0
Subtract 0 from 390 to get 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Let's proceed to step 10:
The number 420 fits into 3900 9 times, leaving a remainder of 120.
Write down 9 as next digit of the result. 
Result so far: 91941.09
If we take 3780 away from 3900, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 11:
When dividing 1200 by 420, we get 2 with a remainder of 360.
The number 2 becomes the next digit in our result. 
Result so far: 91941.092
If we take 840 away from 1200, we end up with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Let's proceed to step 12:
When dividing 3600 by 420, we get 8 with a remainder of 240.
Record the quotient 8 as the next digit in the result. 
Result so far: 91941.0928
The remainder is 240 after subtracting 3360 from 3600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Step 13:
2400 divided by 420 is 5 with a remainder of 300.
Write down 5 as next digit of the result. 
Result so far: 91941.09285
The remainder is 300 after subtracting 2100 from 2400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

On to step 14:
420 can be fit into 3000 7 times, resulting in a remainder of 60.
Record the quotient 7 as the next digit in the result. 
Result so far: 91941.092857
If we take 2940 away from 3000, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 15:
When dividing 600 by 420, we get 1 with a remainder of 180.
The number 1 becomes the next digit in our result. 
Result so far: 91941.0928571
If we take 420 away from 600, we end up with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Going ahead to step 16:
The number 420 fits into 1800 4 times, leaving a remainder of 120.
Use 4 as the next digit of our solution. 
Result so far: 91941.09285714
Deduct 1680 from 1800 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

The quotient of the division is 91941.09285714, and the remainder is 1.2e-07.
