We're dividing 71135539 by 220 
The aim is to understand the frequency of 220 in 71135539.

Advancing to step 1:
If we divide 7 by 220, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 220

Advancing to step 2:
If we divide 71 by 220, we get 0 and a remainder of 71.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 71 leaves us with 71.
Fetch the next digit (1) from the dividend, attach it to 71 and continue: 711 / 220

Step 3:
When dividing 711 by 220, we get 3 with a remainder of 51.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 51 after subtracting 660 from 711.
Include the next digit (3) from the dividend after 51, then repeat: 513 / 220

Step 4:
When dividing 513 by 220, we get 2 with a remainder of 73.
The next digit of our result is 2. 
Result so far: 32.0
If we take 440 away from 513, we end up with 73.
Fetch the next digit (5) from the dividend, attach it to 73 and continue: 735 / 220

On to step 5:
When dividing 735 by 220, we get 3 with a remainder of 75.
Use 3 as the next digit of our solution. 
Result so far: 323.0
Subtracting 660 from 735 leaves us with 75.
Take the next digit (5) from the dividend and append it to 75, then repeat: 755 / 220

Advancing to step 6:
If we divide 755 by 220, we get 3 and a remainder of 95.
Put 3 as the next digit of the answer. 
Result so far: 3233.0
Subtract 660 from 755 to get 95.
Bring next digit (3) of the dividend behind the 95 and repeat the process: 953 / 220

Step 7:
If we divide 953 by 220, we get 4 and a remainder of 73.
The number 4 becomes the next digit in our result. 
Result so far: 32334.0
If we take 880 away from 953, we end up with 73.
Fetch the next digit (9) from the dividend, attach it to 73 and continue: 739 / 220

On to step 8:
739 divided by 220 is 3 with a remainder of 79.
Put 3 as the next digit of the answer. 
Result so far: 323343.0
Subtracting 660 from 739 leaves us with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Step 9:
If we divide 790 by 220, we get 3 and a remainder of 130.
Use 3 as the next digit of our solution. 
Result so far: 323343.3
Subtracting 660 from 790 leaves us with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Advancing to step 10:
The number 220 fits into 1300 5 times, leaving a remainder of 200.
Record the quotient 5 as the next digit in the result. 
Result so far: 323343.35
Subtract 1100 from 1300 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Advancing to step 11:
220 can be fit into 2000 9 times, resulting in a remainder of 20.
Write down 9 as next digit of the result. 
Result so far: 323343.359
Subtracting 1980 from 2000 leaves us 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.

Moving on to step 12:
If we divide 200 by 220, we get 0 and a remainder of 200.
Write down 0 as next digit of the result. 
Result so far: 323343.359
If we subtract 0 from 200, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Going ahead to step 13:
If we divide 2000 by 220, we get 9 and a remainder of 20.
Record the quotient 9 as the next digit in the result. 
Result so far: 323343.35909
Subtracting 1980 from 2000 leaves us 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.

Advancing to step 14:
200 divided by 220 is 0 with a remainder of 200.
The next digit of our result is 0. 
Result so far: 323343.35909
Deduct 0 from 200 and we're left 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.

On to step 15:
220 can be fit into 2000 9 times, resulting in a remainder of 20.
Put 9 as the next digit of the answer. 
Result so far: 323343.3590909
If we take 1980 away from 2000, we end up 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.

Moving on to step 16:
220 goes into 200 0 times with a remainder of 200.
Use 0 as the next digit of our solution. 
Result so far: 323343.3590909
If we subtract 0 from 200, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

After the division, we end up with 323343.3590909 and a remainder of 2e-07.
