We look at the division of 8605253 by 991 
We want to divide 8605253 by 991.

On to step 1:
8 divided by 991 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 991

Going ahead to step 2:
When dividing 86 by 991, we get 0 with a remainder of 86.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 86, we end up with 86.
Append the next digit (0) from the dividend to 86 and continue with: 860 / 991

Step 3:
991 goes into 860 0 times with a remainder of 860.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 860 and we're left with 860.
Bring next digit (5) of the dividend behind the 860 and repeat the process: 8605 / 991

Going ahead to step 4:
When dividing 8605 by 991, we get 8 with a remainder of 677.
The next digit of our result is 8. 
Result so far: 8.0
Deduct 7928 from 8605 and we're left with 677.
Fetch the next digit (2) from the dividend, attach it to 677 and continue: 6772 / 991

Moving on to step 5:
When dividing 6772 by 991, we get 6 with a remainder of 826.
Write down 6 as next digit of the result. 
Result so far: 86.0
Subtracting 5946 from 6772 leaves us with 826.
Bring next digit (5) of the dividend behind the 826 and repeat the process: 8265 / 991

Step 6:
8265 divided by 991 is 8 with a remainder of 337.
The next digit of our result is 8. 
Result so far: 868.0
If we subtract 7928 from 8265, we get 337.
Take the next digit (3) from the dividend and append it to 337, then repeat: 3373 / 991

Let's proceed to step 7:
When dividing 3373 by 991, we get 3 with a remainder of 400.
Record the quotient 3 as the next digit in the result. 
Result so far: 8683.0
The remainder is 400 after subtracting 2973 from 3373.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Step 8:
When dividing 4000 by 991, we get 4 with a remainder of 36.
The next digit of our result is 4. 
Result so far: 8683.4
Subtract 3964 from 4000 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 9:
The number 991 fits into 360 0 times, leaving a remainder of 360.
The number 0 becomes the next digit in our result. 
Result so far: 8683.4
Subtract 0 from 360 to get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Going ahead to step 10:
The number 991 fits into 3600 3 times, leaving a remainder of 627.
The number 3 becomes the next digit in our result. 
Result so far: 8683.403
Deduct 2973 from 3600 and we're left with 627.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6270, and continue the process.

Moving on to step 11:
When dividing 6270 by 991, we get 6 with a remainder of 324.
Put 6 as the next digit of the answer. 
Result so far: 8683.4036
Subtracting 5946 from 6270 leaves us with 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Advancing to step 12:
If we divide 3240 by 991, we get 3 and a remainder of 267.
Record the quotient 3 as the next digit in the result. 
Result so far: 8683.40363
The remainder is 267 after subtracting 2973 from 3240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2670, and continue the process.

Let's proceed to step 13:
991 can be fit into 2670 2 times, resulting in a remainder of 688.
Use 2 as the next digit of our solution. 
Result so far: 8683.403632
If we take 1982 away from 2670, we end up with 688.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6880, and continue the process.

Moving on to step 14:
If we divide 6880 by 991, we get 6 and a remainder of 934.
Put 6 as the next digit of the answer. 
Result so far: 8683.4036326
The remainder is 934 after subtracting 5946 from 6880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9340, and continue the process.

Going ahead to step 15:
The number 991 fits into 9340 9 times, leaving a remainder of 421.
Use 9 as the next digit of our solution. 
Result so far: 8683.40363269
Deduct 8919 from 9340 and we're left with 421.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4210, and continue the process.

The final outcome is 8683.40363269, with a leftover of 4.21e-07.
