Let's divide 52113373 by 220
The aim is to understand the frequency of 220 in 52113373.

Advancing to step 1:
When dividing 5 by 220, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Bring next digit (2) of the dividend behind the 5 and repeat the process: 52 / 220

Let's proceed to step 2:
220 can be fit into 52 0 times, resulting in a remainder of 52.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 52, we get 52.
Append the next digit (1) from the dividend to 52 and continue with: 521 / 220

On to step 3:
220 goes into 521 2 times with a remainder of 81.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 440 from 521 leaves us with 81.
Fetch the next digit (1) from the dividend, attach it to 81 and continue: 811 / 220

Step 4:
The number 220 fits into 811 3 times, leaving a remainder of 151.
Use 3 as the next digit of our solution. 
Result so far: 23.0
Subtract 660 from 811 to get 151.
Include the next digit (3) from the dividend after 151, then repeat: 1513 / 220

Step 5:
When dividing 1513 by 220, we get 6 with a remainder of 193.
The next digit of our result is 6. 
Result so far: 236.0
Subtracting 1320 from 1513 leaves us with 193.
Grab the next digit (3) from the dividend, add it to 193, then carry on: 1933 / 220

Going ahead to step 6:
If we divide 1933 by 220, we get 8 and a remainder of 173.
The next digit of our result is 8. 
Result so far: 2368.0
Subtract 1760 from 1933 to get 173.
Take the next digit (7) from the dividend and append it to 173, then repeat: 1737 / 220

Advancing to step 7:
The number 220 fits into 1737 7 times, leaving a remainder of 197.
The number 7 becomes the next digit in our result. 
Result so far: 23687.0
Deduct 1540 from 1737 and we're left with 197.
Bring next digit (3) of the dividend behind the 197 and repeat the process: 1973 / 220

Advancing to step 8:
If we divide 1973 by 220, we get 8 and a remainder of 213.
Write down 8 as next digit of the result. 
Result so far: 236878.0
If we subtract 1760 from 1973, we get 213.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2130, and continue the process.

On to step 9:
2130 divided by 220 is 9 with a remainder of 150.
Write down 9 as next digit of the result. 
Result so far: 236878.9
Subtract 1980 from 2130 to get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Moving on to step 10:
1500 divided by 220 is 6 with a remainder of 180.
Write down 6 as next digit of the result. 
Result so far: 236878.96
If we subtract 1320 from 1500, 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.

On to step 11:
If we divide 1800 by 220, we get 8 and a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 236878.968
If we subtract 1760 from 1800, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 12:
220 can be fit into 400 1 times, resulting in a remainder of 180.
Write down 1 as next digit of the result. 
Result so far: 236878.9681
Subtracting 220 from 400 leaves us with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Going ahead to step 13:
220 goes into 1800 8 times with a remainder of 40.
The next digit of our result is 8. 
Result so far: 236878.96818
The remainder is 40 after subtracting 1760 from 1800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 14:
400 divided by 220 is 1 with a remainder of 180.
Put 1 as the next digit of the answer. 
Result so far: 236878.968181
Subtracting 220 from 400 leaves us with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Going ahead to step 15:
When dividing 1800 by 220, we get 8 with a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 236878.9681818
Deduct 1760 from 1800 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 16:
400 divided by 220 is 1 with a remainder of 180.
The number 1 becomes the next digit in our result. 
Result so far: 236878.96818181
If we subtract 220 from 400, 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.

After the division, we end up with 236878.96818181 and a remainder of 1.8e-07.
