We look at the division of 975398 by 91 
We're looking to find how many times 91 goes into 975398.

Moving on to step 1:
91 goes into 9 0 times with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Bring next digit (7) of the dividend behind the 9 and repeat the process: 97 / 91

Moving on to step 2:
97 divided by 91 is 1 with a remainder of 6.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 91 from 97 leaves us with 6.
Fetch the next digit (5) from the dividend, attach it to 6 and continue: 65 / 91

Moving on to step 3:
65 divided by 91 is 0 with a remainder of 65.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtract 0 from 65 to get 65.
Append the next digit (3) from the dividend to 65 and continue with: 653 / 91

Advancing to step 4:
653 divided by 91 is 7 with a remainder of 16.
Use 7 as the next digit of our solution. 
Result so far: 107.0
The remainder is 16 after subtracting 637 from 653.
Take the next digit (9) from the dividend and append it to 16, then repeat: 169 / 91

Let's proceed to step 5:
169 divided by 91 is 1 with a remainder of 78.
Write down 1 as next digit of the result. 
Result so far: 1071.0
Deduct 91 from 169 and we're left with 78.
Grab the next digit (8) from the dividend, add it to 78, then carry on: 788 / 91

Let's proceed to step 6:
When dividing 788 by 91, we get 8 with a remainder of 60.
Use 8 as the next digit of our solution. 
Result so far: 10718.0
Subtract 728 from 788 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 7:
When dividing 600 by 91, we get 6 with a remainder of 54.
Put 6 as the next digit of the answer. 
Result so far: 10718.6
If we subtract 546 from 600, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 8:
If we divide 540 by 91, we get 5 and a remainder of 85.
Write down 5 as next digit of the result. 
Result so far: 10718.65
Deduct 455 from 540 and we're left with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

On to step 9:
91 can be fit into 850 9 times, resulting in a remainder of 31.
The number 9 becomes the next digit in our result. 
Result so far: 10718.659
Deduct 819 from 850 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 10:
310 divided by 91 is 3 with a remainder of 37.
Use 3 as the next digit of our solution. 
Result so far: 10718.6593
If we subtract 273 from 310, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 11:
91 goes into 370 4 times with a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 10718.65934
If we subtract 364 from 370, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 12:
91 goes into 60 0 times with a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 10718.65934
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 13:
When dividing 600 by 91, we get 6 with a remainder of 54.
The number 6 becomes the next digit in our result. 
Result so far: 10718.6593406
If we subtract 546 from 600, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 14:
The number 91 fits into 540 5 times, leaving a remainder of 85.
Put 5 as the next digit of the answer. 
Result so far: 10718.65934065
Deduct 455 from 540 and we're left with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

The final outcome is 10718.65934065, with a leftover of 8.5e-08.
