Let's divide 51358027 by 220
The aim is to understand the frequency of 220 in 51358027.

Advancing to step 1:
220 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 220

Moving on to step 2:
220 goes into 51 0 times with a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 51 leaves us with 51.
Bring next digit (3) of the dividend behind the 51 and repeat the process: 513 / 220

Let's proceed to step 3:
The number 220 fits into 513 2 times, leaving a remainder of 73.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 440 from 513 to get 73.
Take the next digit (5) from the dividend and append it to 73, then repeat: 735 / 220

Advancing to step 4:
The number 220 fits into 735 3 times, leaving a remainder of 75.
Write down 3 as next digit of the result. 
Result so far: 23.0
The remainder is 75 after subtracting 660 from 735.
Grab the next digit (8) from the dividend, add it to 75, then carry on: 758 / 220

Advancing to step 5:
When dividing 758 by 220, we get 3 with a remainder of 98.
Record the quotient 3 as the next digit in the result. 
Result so far: 233.0
Subtract 660 from 758 to get 98.
Grab the next digit (0) from the dividend, add it to 98, then carry on: 980 / 220

On to step 6:
220 goes into 980 4 times with a remainder of 100.
The next digit of our result is 4. 
Result so far: 2334.0
The remainder is 100 after subtracting 880 from 980.
Append the next digit (2) from the dividend to 100 and continue with: 1002 / 220

Going ahead to step 7:
220 can be fit into 1002 4 times, resulting in a remainder of 122.
Use 4 as the next digit of our solution. 
Result so far: 23344.0
Subtracting 880 from 1002 leaves us with 122.
Include the next digit (7) from the dividend after 122, then repeat: 1227 / 220

Step 8:
The number 220 fits into 1227 5 times, leaving a remainder of 127.
Record the quotient 5 as the next digit in the result. 
Result so far: 233445.0
The remainder is 127 after subtracting 1100 from 1227.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Step 9:
When dividing 1270 by 220, we get 5 with a remainder of 170.
Write down 5 as next digit of the result. 
Result so far: 233445.5
The remainder is 170 after subtracting 1100 from 1270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Moving on to step 10:
220 goes into 1700 7 times with a remainder of 160.
Put 7 as the next digit of the answer. 
Result so far: 233445.57
Deduct 1540 from 1700 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 11:
If we divide 1600 by 220, we get 7 and a remainder of 60.
Write down 7 as next digit of the result. 
Result so far: 233445.577
Deduct 1540 from 1600 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The final outcome is 233445.577, with a leftover of 0.006.
