We look at the division of 82479690 by 420 
Our goal is to divide 82479690 by 420.

On to step 1:
8 divided by 420 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (2) from the dividend to 8 and continue with: 82 / 420

Step 2:
When dividing 82 by 420, we get 0 with a remainder of 82.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 82 and we're left with 82.
Include the next digit (4) from the dividend after 82, then repeat: 824 / 420

Step 3:
420 goes into 824 1 times with a remainder of 404.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 420 from 824 to get 404.
Bring next digit (7) of the dividend behind the 404 and repeat the process: 4047 / 420

Moving on to step 4:
4047 divided by 420 is 9 with a remainder of 267.
Put 9 as the next digit of the answer. 
Result so far: 19.0
If we subtract 3780 from 4047, we get 267.
Fetch the next digit (9) from the dividend, attach it to 267 and continue: 2679 / 420

On to step 5:
420 can be fit into 2679 6 times, resulting in a remainder of 159.
Record the quotient 6 as the next digit in the result. 
Result so far: 196.0
If we subtract 2520 from 2679, we get 159.
Take the next digit (6) from the dividend and append it to 159, then repeat: 1596 / 420

Advancing to step 6:
When dividing 1596 by 420, we get 3 with a remainder of 336.
Write down 3 as next digit of the result. 
Result so far: 1963.0
Subtracting 1260 from 1596 leaves us with 336.
Include the next digit (9) from the dividend after 336, then repeat: 3369 / 420

On to step 7:
420 goes into 3369 8 times with a remainder of 9.
Put 8 as the next digit of the answer. 
Result so far: 19638.0
The remainder is 9 after subtracting 3360 from 3369.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 420

Moving on to step 8:
When dividing 90 by 420, we get 0 with a remainder of 90.
Use 0 as the next digit of our solution. 
Result so far: 196380.0
Deduct 0 from 90 and we're left with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Let's proceed to step 9:
420 can be fit into 900 2 times, resulting in a remainder of 60.
Put 2 as the next digit of the answer. 
Result so far: 196380.2
If we subtract 840 from 900, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 10:
If we divide 600 by 420, we get 1 and a remainder of 180.
The number 1 becomes the next digit in our result. 
Result so far: 196380.21
If we subtract 420 from 600, we get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Advancing to step 11:
420 goes into 1800 4 times with a remainder of 120.
Write down 4 as next digit of the result. 
Result so far: 196380.214
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.

Step 12:
The number 420 fits into 1200 2 times, leaving a remainder of 360.
Write down 2 as next digit of the result. 
Result so far: 196380.2142
If we subtract 840 from 1200, we get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Moving on to step 13:
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: 196380.21428
Subtracting 3360 from 3600 leaves us with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

On to step 14:
420 goes into 2400 5 times with a remainder of 300.
Record the quotient 5 as the next digit in the result. 
Result so far: 196380.214285
Deduct 2100 from 2400 and we're left 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.

Advancing to step 15:
The number 420 fits into 3000 7 times, leaving a remainder of 60.
The number 7 becomes the next digit in our result. 
Result so far: 196380.2142857
Subtracting 2940 from 3000 leaves us 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.

Step 16:
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: 196380.21428571
If we subtract 420 from 600, we get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Our division results in 196380.21428571 with a remaining 1.8e-07.
