We're dividing 991172 by 23 
We want to figure out the number of times 991172 can be divided by 23.

Step 1:
23 goes into 9 0 times with 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.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 23

Let's proceed to step 2:
When dividing 99 by 23, we get 4 with a remainder of 7.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Deduct 92 from 99 and we're left with 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 23

Step 3:
When dividing 71 by 23, we get 3 with a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 43.0
Deduct 69 from 71 and we're left with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 23

Let's proceed to step 4:
21 divided by 23 is 0 with a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 430.0
The remainder is 21 after subtracting 0 from 21.
Append the next digit (7) from the dividend to 21 and continue with: 217 / 23

Advancing to step 5:
23 goes into 217 9 times with a remainder of 10.
Use 9 as the next digit of our solution. 
Result so far: 4309.0
Subtracting 207 from 217 leaves us with 10.
Append the next digit (2) from the dividend to 10 and continue with: 102 / 23

On to step 6:
When dividing 102 by 23, we get 4 with a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 43094.0
Subtract 92 from 102 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.

On to step 7:
100 divided by 23 is 4 with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 43094.4
The remainder is 8 after subtracting 92 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 8:
When dividing 80 by 23, we get 3 with a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 43094.43
Deduct 69 from 80 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 9:
23 can be fit into 110 4 times, resulting in a remainder of 18.
The number 4 becomes the next digit in our result. 
Result so far: 43094.434
If we subtract 92 from 110, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 10:
The number 23 fits into 180 7 times, leaving a remainder of 19.
Write down 7 as next digit of the result. 
Result so far: 43094.4347
Deduct 161 from 180 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 11:
The number 23 fits into 190 8 times, leaving a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 43094.43478
Subtracting 184 from 190 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 12:
60 divided by 23 is 2 with a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 43094.434782
Deduct 46 from 60 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 13:
If we divide 140 by 23, we get 6 and a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 43094.4347826
If we subtract 138 from 140, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 14:
23 goes into 20 0 times with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 43094.4347826
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 43094.4347826, with a leftover of 2e-08.
