4792561 ÷ 220 
The aim is to understand the frequency of 220 in 4792561.

Moving on to step 1:
4 divided by 220 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (7) from the dividend and append it to 4, then repeat: 47 / 220

Let's proceed to step 2:
If we divide 47 by 220, we get 0 and a remainder of 47.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 47, we get 47.
Bring next digit (9) of the dividend behind the 47 and repeat the process: 479 / 220

Step 3:
The number 220 fits into 479 2 times, leaving a remainder of 39.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 39 after subtracting 440 from 479.
Fetch the next digit (2) from the dividend, attach it to 39 and continue: 392 / 220

Let's proceed to step 4:
If we divide 392 by 220, we get 1 and a remainder of 172.
Put 1 as the next digit of the answer. 
Result so far: 21.0
Deduct 220 from 392 and we're left with 172.
Bring next digit (5) of the dividend behind the 172 and repeat the process: 1725 / 220

Advancing to step 5:
When dividing 1725 by 220, we get 7 with a remainder of 185.
Use 7 as the next digit of our solution. 
Result so far: 217.0
Subtract 1540 from 1725 to get 185.
Bring next digit (6) of the dividend behind the 185 and repeat the process: 1856 / 220

Advancing to step 6:
The number 220 fits into 1856 8 times, leaving a remainder of 96.
Record the quotient 8 as the next digit in the result. 
Result so far: 2178.0
Subtracting 1760 from 1856 leaves us with 96.
Include the next digit (1) from the dividend after 96, then repeat: 961 / 220

Moving on to step 7:
If we divide 961 by 220, we get 4 and a remainder of 81.
Write down 4 as next digit of the result. 
Result so far: 21784.0
Deduct 880 from 961 and we're left with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

On to step 8:
The number 220 fits into 810 3 times, leaving a remainder of 150.
Write down 3 as next digit of the result. 
Result so far: 21784.3
If we subtract 660 from 810, we 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.

On to step 9:
220 goes into 1500 6 times with a remainder of 180.
Record the quotient 6 as the next digit in the result. 
Result so far: 21784.36
Subtracting 1320 from 1500 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.

On to step 10:
If we divide 1800 by 220, we get 8 and a remainder of 40.
The next digit of our result is 8. 
Result so far: 21784.368
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.

Advancing to step 11:
220 can be fit into 400 1 times, resulting in a remainder of 180.
Use 1 as the next digit of our solution. 
Result so far: 21784.3681
If we take 220 away from 400, we end up 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.

Let's proceed to step 12:
The number 220 fits into 1800 8 times, leaving a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 21784.36818
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.

Step 13:
The number 220 fits into 400 1 times, leaving a remainder of 180.
Use 1 as the next digit of our solution. 
Result so far: 21784.368181
Deduct 220 from 400 and we're left 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.

On to step 14:
1800 divided by 220 is 8 with a remainder of 40.
Record the quotient 8 as the next digit in the result. 
Result so far: 21784.3681818
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.

Advancing to step 15:
The number 220 fits into 400 1 times, leaving a remainder of 180.
The number 1 becomes the next digit in our result. 
Result so far: 21784.36818181
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.

The final outcome is 21784.36818181, with a leftover of 1.8e-07.
