We look at the division of 42923 by 91 
We want to figure out the number of times 42923 can be divided by 91.

Step 1:
When dividing 4 by 91, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 91

Let's proceed to step 2:
The number 91 fits into 42 0 times, leaving a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Grab the next digit (9) from the dividend, add it to 42, then carry on: 429 / 91

Step 3:
If we divide 429 by 91, we get 4 and a remainder of 65.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 364 away from 429, we end up with 65.
Grab the next digit (2) from the dividend, add it to 65, then carry on: 652 / 91

Going ahead to step 4:
If we divide 652 by 91, we get 7 and a remainder of 15.
The next digit of our result is 7. 
Result so far: 47.0
The remainder is 15 after subtracting 637 from 652.
Append the next digit (3) from the dividend to 15 and continue with: 153 / 91

Advancing to step 5:
If we divide 153 by 91, we get 1 and a remainder of 62.
Record the quotient 1 as the next digit in the result. 
Result so far: 471.0
Subtracting 91 from 153 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 6:
91 can be fit into 620 6 times, resulting in a remainder of 74.
The number 6 becomes the next digit in our result. 
Result so far: 471.6
Subtracting 546 from 620 leaves us with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Going ahead to step 7:
The number 91 fits into 740 8 times, leaving a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 471.68
Deduct 728 from 740 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 8:
120 divided by 91 is 1 with a remainder of 29.
Put 1 as the next digit of the answer. 
Result so far: 471.681
If we subtract 91 from 120, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 9:
91 can be fit into 290 3 times, resulting in a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 471.6813
Subtract 273 from 290 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 10:
If we divide 170 by 91, we get 1 and a remainder of 79.
Put 1 as the next digit of the answer. 
Result so far: 471.68131
Subtract 91 from 170 to get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Moving on to step 11:
91 goes into 790 8 times with a remainder of 62.
Put 8 as the next digit of the answer. 
Result so far: 471.681318
Subtracting 728 from 790 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 12:
If we divide 620 by 91, we get 6 and a remainder of 74.
Record the quotient 6 as the next digit in the result. 
Result so far: 471.6813186
Subtract 546 from 620 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

On to step 13:
If we divide 740 by 91, we get 8 and a remainder of 12.
The next digit of our result is 8. 
Result so far: 471.68131868
If we subtract 728 from 740, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final outcome is 471.68131868, with a leftover of 1.2e-08.
