40534554 divided by 420 
We want to figure out the number of times 40534554 can be divided by 420.

Moving on to step 1:
If we divide 4 by 420, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 420

Going ahead to step 2:
The number 420 fits into 40 0 times, leaving a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 40, we end up with 40.
Grab the next digit (5) from the dividend, add it to 40, then carry on: 405 / 420

Advancing to step 3:
When dividing 405 by 420, we get 0 with a remainder of 405.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 405 to get 405.
Grab the next digit (3) from the dividend, add it to 405, then carry on: 4053 / 420

Step 4:
The number 420 fits into 4053 9 times, leaving a remainder of 273.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Deduct 3780 from 4053 and we're left with 273.
Bring next digit (4) of the dividend behind the 273 and repeat the process: 2734 / 420

Going ahead to step 5:
420 goes into 2734 6 times with a remainder of 214.
Write down 6 as next digit of the result. 
Result so far: 96.0
The remainder is 214 after subtracting 2520 from 2734.
Bring next digit (5) of the dividend behind the 214 and repeat the process: 2145 / 420

Step 6:
When dividing 2145 by 420, we get 5 with a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 965.0
If we take 2100 away from 2145, we end up with 45.
Include the next digit (5) from the dividend after 45, then repeat: 455 / 420

Moving on to step 7:
The number 420 fits into 455 1 times, leaving a remainder of 35.
The number 1 becomes the next digit in our result. 
Result so far: 9651.0
Subtract 420 from 455 to get 35.
Append the next digit (4) from the dividend to 35 and continue with: 354 / 420

Going ahead to step 8:
If we divide 354 by 420, we get 0 and a remainder of 354.
The number 0 becomes the next digit in our result. 
Result so far: 96510.0
Subtracting 0 from 354 leaves us with 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

Let's proceed to step 9:
If we divide 3540 by 420, we get 8 and a remainder of 180.
The next digit of our result is 8. 
Result so far: 96510.8
The remainder is 180 after subtracting 3360 from 3540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

On to step 10:
If we divide 1800 by 420, we get 4 and a remainder of 120.
Use 4 as the next digit of our solution. 
Result so far: 96510.84
Subtracting 1680 from 1800 leaves us 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.

Moving on to step 11:
420 goes into 1200 2 times with a remainder of 360.
The number 2 becomes the next digit in our result. 
Result so far: 96510.842
Deduct 840 from 1200 and we're left 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.

On to step 12:
420 can be fit into 3600 8 times, resulting in a remainder of 240.
Put 8 as the next digit of the answer. 
Result so far: 96510.8428
Subtract 3360 from 3600 to get 240.
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:
The number 420 fits into 2400 5 times, leaving a remainder of 300.
Put 5 as the next digit of the answer. 
Result so far: 96510.84285
Subtracting 2100 from 2400 leaves us with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Moving on to step 14:
If we divide 3000 by 420, we get 7 and a remainder of 60.
Record the quotient 7 as the next digit in the result. 
Result so far: 96510.842857
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.

On to step 15:
When dividing 600 by 420, we get 1 with a remainder of 180.
The next digit of our result is 1. 
Result so far: 96510.8428571
Deduct 420 from 600 and we're left 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.

Let's proceed to step 16:
420 can be fit into 1800 4 times, resulting in a remainder of 120.
Put 4 as the next digit of the answer. 
Result so far: 96510.84285714
The remainder is 120 after subtracting 1680 from 1800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

After the division, we end up with 96510.84285714 and a remainder of 1.2e-07.
