We look at the division of 842157 by 91 
Let's see how many times 91 fits into 842157.

Advancing to step 1:
91 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 91

Step 2:
When dividing 84 by 91, we get 0 with a remainder of 84.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 84 to get 84.
Take the next digit (2) from the dividend and append it to 84, then repeat: 842 / 91

Moving on to step 3:
If we divide 842 by 91, we get 9 and a remainder of 23.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Deduct 819 from 842 and we're left with 23.
Take the next digit (1) from the dividend and append it to 23, then repeat: 231 / 91

Advancing to step 4:
231 divided by 91 is 2 with a remainder of 49.
Record the quotient 2 as the next digit in the result. 
Result so far: 92.0
If we take 182 away from 231, we end up with 49.
Bring next digit (5) of the dividend behind the 49 and repeat the process: 495 / 91

On to step 5:
495 divided by 91 is 5 with a remainder of 40.
Write down 5 as next digit of the result. 
Result so far: 925.0
The remainder is 40 after subtracting 455 from 495.
Include the next digit (7) from the dividend after 40, then repeat: 407 / 91

On to step 6:
If we divide 407 by 91, we get 4 and a remainder of 43.
Write down 4 as next digit of the result. 
Result so far: 9254.0
If we subtract 364 from 407, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Going ahead to step 7:
The number 91 fits into 430 4 times, leaving a remainder of 66.
Put 4 as the next digit of the answer. 
Result so far: 9254.4
Deduct 364 from 430 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 8:
The number 91 fits into 660 7 times, leaving a remainder of 23.
Use 7 as the next digit of our solution. 
Result so far: 9254.47
If we take 637 away from 660, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 9:
The number 91 fits into 230 2 times, leaving a remainder of 48.
The next digit of our result is 2. 
Result so far: 9254.472
Deduct 182 from 230 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 10:
480 divided by 91 is 5 with a remainder of 25.
The next digit of our result is 5. 
Result so far: 9254.4725
Subtract 455 from 480 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 11:
91 goes into 250 2 times with a remainder of 68.
Write down 2 as next digit of the result. 
Result so far: 9254.47252
If we take 182 away from 250, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 12:
91 goes into 680 7 times with a remainder of 43.
Use 7 as the next digit of our solution. 
Result so far: 9254.472527
Subtract 637 from 680 to get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 13:
The number 91 fits into 430 4 times, leaving a remainder of 66.
Record the quotient 4 as the next digit in the result. 
Result so far: 9254.4725274
If we take 364 away from 430, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 14:
91 can be fit into 660 7 times, resulting in a remainder of 23.
Record the quotient 7 as the next digit in the result. 
Result so far: 9254.47252747
Subtract 637 from 660 to 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.

The final outcome is 9254.47252747, with a leftover of 2.3e-08.
