We look at the division of 13237855 by 820 
We want to divide 13237855 by 820.

Step 1:
The number 820 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 820

Going ahead to step 2:
When dividing 13 by 820, we get 0 with a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 13 after subtracting 0 from 13.
Fetch the next digit (2) from the dividend, attach it to 13 and continue: 132 / 820

Moving on to step 3:
820 can be fit into 132 0 times, resulting in a remainder of 132.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 132, we end up with 132.
Take the next digit (3) from the dividend and append it to 132, then repeat: 1323 / 820

Step 4:
The number 820 fits into 1323 1 times, leaving a remainder of 503.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 820 from 1323, we get 503.
Bring next digit (7) of the dividend behind the 503 and repeat the process: 5037 / 820

Going ahead to step 5:
820 goes into 5037 6 times with a remainder of 117.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
Subtract 4920 from 5037 to get 117.
Append the next digit (8) from the dividend to 117 and continue with: 1178 / 820

Moving on to step 6:
If we divide 1178 by 820, we get 1 and a remainder of 358.
Use 1 as the next digit of our solution. 
Result so far: 161.0
If we take 820 away from 1178, we end up with 358.
Fetch the next digit (5) from the dividend, attach it to 358 and continue: 3585 / 820

Moving on to step 7:
When dividing 3585 by 820, we get 4 with a remainder of 305.
Record the quotient 4 as the next digit in the result. 
Result so far: 1614.0
Deduct 3280 from 3585 and we're left with 305.
Append the next digit (5) from the dividend to 305 and continue with: 3055 / 820

Let's proceed to step 8:
When dividing 3055 by 820, we get 3 with a remainder of 595.
Record the quotient 3 as the next digit in the result. 
Result so far: 16143.0
If we subtract 2460 from 3055, we get 595.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5950, and continue the process.

On to step 9:
820 goes into 5950 7 times with a remainder of 210.
The number 7 becomes the next digit in our result. 
Result so far: 16143.7
The remainder is 210 after subtracting 5740 from 5950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Moving on to step 10:
2100 divided by 820 is 2 with a remainder of 460.
Record the quotient 2 as the next digit in the result. 
Result so far: 16143.72
Subtracting 1640 from 2100 leaves us with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Going ahead to step 11:
4600 divided by 820 is 5 with a remainder of 500.
Record the quotient 5 as the next digit in the result. 
Result so far: 16143.725
Subtracting 4100 from 4600 leaves us with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Going ahead to step 12:
820 can be fit into 5000 6 times, resulting in a remainder of 80.
Write down 6 as next digit of the result. 
Result so far: 16143.7256
The remainder is 80 after subtracting 4920 from 5000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 13:
820 can be fit into 800 0 times, resulting in a remainder of 800.
Record the quotient 0 as the next digit in the result. 
Result so far: 16143.7256
Subtract 0 from 800 to get 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

On to step 14:
When dividing 8000 by 820, we get 9 with a remainder of 620.
Write down 9 as next digit of the result. 
Result so far: 16143.725609
Deduct 7380 from 8000 and we're left with 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

On to step 15:
6200 divided by 820 is 7 with a remainder of 460.
Use 7 as the next digit of our solution. 
Result so far: 16143.7256097
If we take 5740 away from 6200, we end up with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Advancing to step 16:
If we divide 4600 by 820, we get 5 and a remainder of 500.
Use 5 as the next digit of our solution. 
Result so far: 16143.72560975
If we take 4100 away from 4600, we end up with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

The final result is 16143.72560975 with a remainder of 5e-07.
