18171743 ÷ 220 
The aim is to understand the frequency of 220 in 18171743.

Moving on to step 1:
220 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 220

On to step 2:
If we divide 18 by 220, we get 0 and a remainder of 18.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 18 and we're left with 18.
Grab the next digit (1) from the dividend, add it to 18, then carry on: 181 / 220

Step 3:
220 goes into 181 0 times with a remainder of 181.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 181 leaves us with 181.
Take the next digit (7) from the dividend and append it to 181, then repeat: 1817 / 220

Let's proceed to step 4:
220 can be fit into 1817 8 times, resulting in a remainder of 57.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we subtract 1760 from 1817, we get 57.
Append the next digit (1) from the dividend to 57 and continue with: 571 / 220

On to step 5:
When dividing 571 by 220, we get 2 with a remainder of 131.
The next digit of our result is 2. 
Result so far: 82.0
If we subtract 440 from 571, we get 131.
Grab the next digit (7) from the dividend, add it to 131, then carry on: 1317 / 220

On to step 6:
The number 220 fits into 1317 5 times, leaving a remainder of 217.
Write down 5 as next digit of the result. 
Result so far: 825.0
Subtracting 1100 from 1317 leaves us with 217.
Append the next digit (4) from the dividend to 217 and continue with: 2174 / 220

Let's proceed to step 7:
When dividing 2174 by 220, we get 9 with a remainder of 194.
The next digit of our result is 9. 
Result so far: 8259.0
Subtract 1980 from 2174 to get 194.
Take the next digit (3) from the dividend and append it to 194, then repeat: 1943 / 220

Advancing to step 8:
220 can be fit into 1943 8 times, resulting in a remainder of 183.
The next digit of our result is 8. 
Result so far: 82598.0
Deduct 1760 from 1943 and we're left with 183.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

Let's proceed to step 9:
1830 divided by 220 is 8 with a remainder of 70.
The number 8 becomes the next digit in our result. 
Result so far: 82598.8
Subtracting 1760 from 1830 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 10:
The number 220 fits into 700 3 times, leaving a remainder of 40.
Use 3 as the next digit of our solution. 
Result so far: 82598.83
If we take 660 away from 700, we end up 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 11:
If we divide 400 by 220, we get 1 and a remainder of 180.
Write down 1 as next digit of the result. 
Result so far: 82598.831
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.

Advancing to step 12:
When dividing 1800 by 220, we get 8 with a remainder of 40.
Put 8 as the next digit of the answer. 
Result so far: 82598.8318
Subtract 1760 from 1800 to 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 13:
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: 82598.83181
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.

Advancing to step 14:
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: 82598.831818
If we take 1760 away from 1800, we end up 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.

Going ahead to step 15:
220 can be fit into 400 1 times, resulting in a remainder of 180.
The number 1 becomes the next digit in our result. 
Result so far: 82598.8318181
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 16:
The number 220 fits into 1800 8 times, leaving a remainder of 40.
Record the quotient 8 as the next digit in the result. 
Result so far: 82598.83181818
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.

The quotient of the division is 82598.83181818, and the remainder is 4e-08.
