Let's divide 81203704 by 220
Our goal is to divide 81203704 by 220.

Let's proceed to step 1:
When dividing 8 by 220, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 220

On to step 2:
220 goes into 81 0 times with a remainder of 81.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 81, we get 81.
Grab the next digit (2) from the dividend, add it to 81, then carry on: 812 / 220

Going ahead to step 3:
The number 220 fits into 812 3 times, leaving a remainder of 152.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 660 away from 812, we end up with 152.
Bring next digit (0) of the dividend behind the 152 and repeat the process: 1520 / 220

Let's proceed to step 4:
If we divide 1520 by 220, we get 6 and a remainder of 200.
The number 6 becomes the next digit in our result. 
Result so far: 36.0
Subtract 1320 from 1520 to get 200.
Append the next digit (3) from the dividend to 200 and continue with: 2003 / 220

Step 5:
When dividing 2003 by 220, we get 9 with a remainder of 23.
Put 9 as the next digit of the answer. 
Result so far: 369.0
Subtract 1980 from 2003 to get 23.
Grab the next digit (7) from the dividend, add it to 23, then carry on: 237 / 220

Step 6:
When dividing 237 by 220, we get 1 with a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 3691.0
Subtract 220 from 237 to get 17.
Fetch the next digit (0) from the dividend, attach it to 17 and continue: 170 / 220

On to step 7:
When dividing 170 by 220, we get 0 with a remainder of 170.
The next digit of our result is 0. 
Result so far: 36910.0
If we take 0 away from 170, we end up with 170.
Include the next digit (4) from the dividend after 170, then repeat: 1704 / 220

Step 8:
220 can be fit into 1704 7 times, resulting in a remainder of 164.
Write down 7 as next digit of the result. 
Result so far: 369107.0
Subtract 1540 from 1704 to get 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Let's proceed to step 9:
220 can be fit into 1640 7 times, resulting in a remainder of 100.
Record the quotient 7 as the next digit in the result. 
Result so far: 369107.7
If we subtract 1540 from 1640, we 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.

Advancing to step 10:
When dividing 1000 by 220, we get 4 with a remainder of 120.
The number 4 becomes the next digit in our result. 
Result so far: 369107.74
If we take 880 away from 1000, we end up 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.

Going ahead to step 11:
1200 divided by 220 is 5 with a remainder of 100.
Record the quotient 5 as the next digit in the result. 
Result so far: 369107.745
If we take 1100 away from 1200, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 12:
220 can be fit into 1000 4 times, resulting in a remainder of 120.
Use 4 as the next digit of our solution. 
Result so far: 369107.7454
Subtracting 880 from 1000 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.

Going ahead to step 13:
If we divide 1200 by 220, we get 5 and a remainder of 100.
The number 5 becomes the next digit in our result. 
Result so far: 369107.74545
Deduct 1100 from 1200 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Moving on to step 14:
When dividing 1000 by 220, we get 4 with a remainder of 120.
The number 4 becomes the next digit in our result. 
Result so far: 369107.745454
Subtracting 880 from 1000 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.

Going ahead to step 15:
When dividing 1200 by 220, we get 5 with a remainder of 100.
The next digit of our result is 5. 
Result so far: 369107.7454545
Subtract 1100 from 1200 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.

Advancing to step 16:
220 can be fit into 1000 4 times, resulting in a remainder of 120.
Write down 4 as next digit of the result. 
Result so far: 369107.74545454
Deduct 880 from 1000 and we're left 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.

The final outcome is 369107.74545454, with a leftover of 1.2e-07.
