We look at the division of 90295984 by 420 
Let's see how many times 420 fits into 90295984.

Let's proceed to step 1:
When dividing 9 by 420, we get 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 420

Going ahead to step 2:
420 goes into 90 0 times with a remainder of 90.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 90, we end up with 90.
Grab the next digit (2) from the dividend, add it to 90, then carry on: 902 / 420

Going ahead to step 3:
420 can be fit into 902 2 times, resulting in a remainder of 62.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 840 from 902 to get 62.
Take the next digit (9) from the dividend and append it to 62, then repeat: 629 / 420

Moving on to step 4:
The number 420 fits into 629 1 times, leaving a remainder of 209.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
The remainder is 209 after subtracting 420 from 629.
Append the next digit (5) from the dividend to 209 and continue with: 2095 / 420

Advancing to step 5:
420 goes into 2095 4 times with a remainder of 415.
The next digit of our result is 4. 
Result so far: 214.0
Deduct 1680 from 2095 and we're left with 415.
Grab the next digit (9) from the dividend, add it to 415, then carry on: 4159 / 420

Advancing to step 6:
4159 divided by 420 is 9 with a remainder of 379.
Put 9 as the next digit of the answer. 
Result so far: 2149.0
Subtracting 3780 from 4159 leaves us with 379.
Fetch the next digit (8) from the dividend, attach it to 379 and continue: 3798 / 420

Advancing to step 7:
If we divide 3798 by 420, we get 9 and a remainder of 18.
The number 9 becomes the next digit in our result. 
Result so far: 21499.0
The remainder is 18 after subtracting 3780 from 3798.
Bring next digit (4) of the dividend behind the 18 and repeat the process: 184 / 420

Moving on to step 8:
When dividing 184 by 420, we get 0 with a remainder of 184.
Record the quotient 0 as the next digit in the result. 
Result so far: 214990.0
If we subtract 0 from 184, we get 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Going ahead to step 9:
420 can be fit into 1840 4 times, resulting in a remainder of 160.
Use 4 as the next digit of our solution. 
Result so far: 214990.4
Deduct 1680 from 1840 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 10:
420 goes into 1600 3 times with a remainder of 340.
Put 3 as the next digit of the answer. 
Result so far: 214990.43
If we subtract 1260 from 1600, we get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Step 11:
When dividing 3400 by 420, we get 8 with a remainder of 40.
The number 8 becomes the next digit in our result. 
Result so far: 214990.438
The remainder is 40 after subtracting 3360 from 3400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 12:
400 divided by 420 is 0 with a remainder of 400.
The number 0 becomes the next digit in our result. 
Result so far: 214990.438
Subtract 0 from 400 to get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Going ahead to step 13:
If we divide 4000 by 420, we get 9 and a remainder of 220.
Record the quotient 9 as the next digit in the result. 
Result so far: 214990.43809
If we take 3780 away from 4000, we end up with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Going ahead to step 14:
The number 420 fits into 2200 5 times, leaving a remainder of 100.
Write down 5 as next digit of the result. 
Result so far: 214990.438095
Subtract 2100 from 2200 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 15:
420 goes into 1000 2 times with a remainder of 160.
The number 2 becomes the next digit in our result. 
Result so far: 214990.4380952
Subtract 840 from 1000 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 16:
The number 420 fits into 1600 3 times, leaving a remainder of 340.
Use 3 as the next digit of our solution. 
Result so far: 214990.43809523
Subtracting 1260 from 1600 leaves us with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

The final result is 214990.43809523 with a remainder of 3.4e-07.
