We divide 172118 by 55
We want to figure out the number of times 172118 can be divided by 55.

Going ahead to step 1:
If we divide 1 by 55, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 55

Let's proceed to step 2:
55 goes into 17 0 times with a remainder of 17.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 17 leaves us with 17.
Include the next digit (2) from the dividend after 17, then repeat: 172 / 55

Let's proceed to step 3:
55 can be fit into 172 3 times, resulting in a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 165 from 172, we get 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 55

Let's proceed to step 4:
55 can be fit into 71 1 times, resulting in a remainder of 16.
Write down 1 as next digit of the result. 
Result so far: 31.0
The remainder is 16 after subtracting 55 from 71.
Fetch the next digit (1) from the dividend, attach it to 16 and continue: 161 / 55

Step 5:
161 divided by 55 is 2 with a remainder of 51.
Write down 2 as next digit of the result. 
Result so far: 312.0
Subtract 110 from 161 to get 51.
Include the next digit (8) from the dividend after 51, then repeat: 518 / 55

On to step 6:
55 can be fit into 518 9 times, resulting in a remainder of 23.
Use 9 as the next digit of our solution. 
Result so far: 3129.0
If we subtract 495 from 518, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 7:
55 can be fit into 230 4 times, resulting in a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 3129.4
If we subtract 220 from 230, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
If we divide 100 by 55, we get 1 and a remainder of 45.
Use 1 as the next digit of our solution. 
Result so far: 3129.41
Subtract 55 from 100 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 9:
55 can be fit into 450 8 times, resulting in a remainder of 10.
Put 8 as the next digit of the answer. 
Result so far: 3129.418
Deduct 440 from 450 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 10:
If we divide 100 by 55, we get 1 and a remainder of 45.
Record the quotient 1 as the next digit in the result. 
Result so far: 3129.4181
Subtract 55 from 100 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 11:
The number 55 fits into 450 8 times, leaving a remainder of 10.
Record the quotient 8 as the next digit in the result. 
Result so far: 3129.41818
The remainder is 10 after subtracting 440 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 12:
If we divide 100 by 55, we get 1 and a remainder of 45.
The next digit of our result is 1. 
Result so far: 3129.418181
Deduct 55 from 100 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 13:
55 can be fit into 450 8 times, resulting in a remainder of 10.
The next digit of our result is 8. 
Result so far: 3129.4181818
Subtracting 440 from 450 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 14:
55 goes into 100 1 times with a remainder of 45.
Use 1 as the next digit of our solution. 
Result so far: 3129.41818181
If we take 55 away from 100, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

The final outcome is 3129.41818181, with a leftover of 4.5e-08.
