We're dividing 991171 by 54 
We want to figure out the number of times 991171 can be divided by 54.

Going ahead to step 1:
If we divide 9 by 54, we get 0 and a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 54

Advancing to step 2:
99 divided by 54 is 1 with a remainder of 45.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 54 from 99 to get 45.
Take the next digit (1) from the dividend and append it to 45, then repeat: 451 / 54

Step 3:
If we divide 451 by 54, we get 8 and a remainder of 19.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
Subtract 432 from 451 to get 19.
Fetch the next digit (1) from the dividend, attach it to 19 and continue: 191 / 54

Step 4:
The number 54 fits into 191 3 times, leaving a remainder of 29.
Record the quotient 3 as the next digit in the result. 
Result so far: 183.0
Subtract 162 from 191 to get 29.
Include the next digit (7) from the dividend after 29, then repeat: 297 / 54

Advancing to step 5:
If we divide 297 by 54, we get 5 and a remainder of 27.
Use 5 as the next digit of our solution. 
Result so far: 1835.0
Deduct 270 from 297 and we're left with 27.
Grab the next digit (1) from the dividend, add it to 27, then carry on: 271 / 54

Going ahead to step 6:
When dividing 271 by 54, we get 5 with a remainder of 1.
Write down 5 as next digit of the result. 
Result so far: 18355.0
If we subtract 270 from 271, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 7:
10 divided by 54 is 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 18355.0
If we take 0 away from 10, we end up 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.

Moving on to step 8:
100 divided by 54 is 1 with a remainder of 46.
Put 1 as the next digit of the answer. 
Result so far: 18355.01
Subtracting 54 from 100 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 9:
If we divide 460 by 54, we get 8 and a remainder of 28.
Write down 8 as next digit of the result. 
Result so far: 18355.018
If we subtract 432 from 460, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 10:
The number 54 fits into 280 5 times, leaving a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 18355.0185
Subtract 270 from 280 to 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.

Going ahead to step 11:
If we divide 100 by 54, we get 1 and a remainder of 46.
The number 1 becomes the next digit in our result. 
Result so far: 18355.01851
If we take 54 away from 100, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 12:
The number 54 fits into 460 8 times, leaving a remainder of 28.
Use 8 as the next digit of our solution. 
Result so far: 18355.018518
Subtract 432 from 460 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 13:
When dividing 280 by 54, we get 5 with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 18355.0185185
The remainder is 10 after subtracting 270 from 280.
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 14:
When dividing 100 by 54, we get 1 with a remainder of 46.
Use 1 as the next digit of our solution. 
Result so far: 18355.01851851
Subtracting 54 from 100 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

After the division, we end up with 18355.01851851 and a remainder of 4.6e-08.
