We look at the division of 57267965 by 420 
Our goal is to divide 57267965 by 420.

Step 1:
The number 420 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 420

On to step 2:
57 divided by 420 is 0 with a remainder of 57.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 57 and we're left with 57.
Take the next digit (2) from the dividend and append it to 57, then repeat: 572 / 420

On to step 3:
572 divided by 420 is 1 with a remainder of 152.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 152 after subtracting 420 from 572.
Bring next digit (6) of the dividend behind the 152 and repeat the process: 1526 / 420

On to step 4:
420 can be fit into 1526 3 times, resulting in a remainder of 266.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Subtracting 1260 from 1526 leaves us with 266.
Append the next digit (7) from the dividend to 266 and continue with: 2667 / 420

Going ahead to step 5:
The number 420 fits into 2667 6 times, leaving a remainder of 147.
Write down 6 as next digit of the result. 
Result so far: 136.0
The remainder is 147 after subtracting 2520 from 2667.
Fetch the next digit (9) from the dividend, attach it to 147 and continue: 1479 / 420

Going ahead to step 6:
When dividing 1479 by 420, we get 3 with a remainder of 219.
The number 3 becomes the next digit in our result. 
Result so far: 1363.0
If we subtract 1260 from 1479, we get 219.
Grab the next digit (6) from the dividend, add it to 219, then carry on: 2196 / 420

Moving on to step 7:
420 can be fit into 2196 5 times, resulting in a remainder of 96.
Record the quotient 5 as the next digit in the result. 
Result so far: 13635.0
Subtract 2100 from 2196 to get 96.
Bring next digit (5) of the dividend behind the 96 and repeat the process: 965 / 420

On to step 8:
965 divided by 420 is 2 with a remainder of 125.
Record the quotient 2 as the next digit in the result. 
Result so far: 136352.0
Subtract 840 from 965 to get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Advancing to step 9:
1250 divided by 420 is 2 with a remainder of 410.
Use 2 as the next digit of our solution. 
Result so far: 136352.2
The remainder is 410 after subtracting 840 from 1250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Step 10:
The number 420 fits into 4100 9 times, leaving a remainder of 320.
The number 9 becomes the next digit in our result. 
Result so far: 136352.29
If we take 3780 away from 4100, we end up with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Let's proceed to step 11:
420 goes into 3200 7 times with a remainder of 260.
Record the quotient 7 as the next digit in the result. 
Result so far: 136352.297
The remainder is 260 after subtracting 2940 from 3200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Advancing to step 12:
When dividing 2600 by 420, we get 6 with a remainder of 80.
Use 6 as the next digit of our solution. 
Result so far: 136352.2976
The remainder is 80 after subtracting 2520 from 2600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 13:
When dividing 800 by 420, we get 1 with a remainder of 380.
Put 1 as the next digit of the answer. 
Result so far: 136352.29761
Subtracting 420 from 800 leaves us with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Advancing to step 14:
420 goes into 3800 9 times with a remainder of 20.
Write down 9 as next digit of the result. 
Result so far: 136352.297619
Deduct 3780 from 3800 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 15:
If we divide 200 by 420, we get 0 and a remainder of 200.
Use 0 as the next digit of our solution. 
Result so far: 136352.297619
Subtracting 0 from 200 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Moving on to step 16:
420 can be fit into 2000 4 times, resulting in a remainder of 320.
Record the quotient 4 as the next digit in the result. 
Result so far: 136352.29761904
Subtract 1680 from 2000 to get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

The final result is 136352.29761904 with a remainder of 3.2e-07.
