Let's divide 86710921 by 953
We want to divide 86710921 by 953.

Step 1:
If we divide 8 by 953, we get 0 and 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.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 953

Step 2:
86 divided by 953 is 0 with a remainder of 86.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 86 leaves us with 86.
Bring next digit (7) of the dividend behind the 86 and repeat the process: 867 / 953

Going ahead to step 3:
The number 953 fits into 867 0 times, leaving a remainder of 867.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 867, we get 867.
Fetch the next digit (1) from the dividend, attach it to 867 and continue: 8671 / 953

Advancing to step 4:
8671 divided by 953 is 9 with a remainder of 94.
The next digit of our result is 9. 
Result so far: 9.0
Subtracting 8577 from 8671 leaves us with 94.
Append the next digit (0) from the dividend to 94 and continue with: 940 / 953

Moving on to step 5:
The number 953 fits into 940 0 times, leaving a remainder of 940.
Use 0 as the next digit of our solution. 
Result so far: 90.0
If we take 0 away from 940, we end up with 940.
Grab the next digit (9) from the dividend, add it to 940, then carry on: 9409 / 953

Moving on to step 6:
953 can be fit into 9409 9 times, resulting in a remainder of 832.
The number 9 becomes the next digit in our result. 
Result so far: 909.0
Deduct 8577 from 9409 and we're left with 832.
Append the next digit (2) from the dividend to 832 and continue with: 8322 / 953

Step 7:
The number 953 fits into 8322 8 times, leaving a remainder of 698.
The number 8 becomes the next digit in our result. 
Result so far: 9098.0
Subtract 7624 from 8322 to get 698.
Grab the next digit (1) from the dividend, add it to 698, then carry on: 6981 / 953

On to step 8:
The number 953 fits into 6981 7 times, leaving a remainder of 310.
Use 7 as the next digit of our solution. 
Result so far: 90987.0
Subtracting 6671 from 6981 leaves us with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Going ahead to step 9:
953 goes into 3100 3 times with a remainder of 241.
Record the quotient 3 as the next digit in the result. 
Result so far: 90987.3
If we subtract 2859 from 3100, we get 241.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2410, and continue the process.

Advancing to step 10:
If we divide 2410 by 953, we get 2 and a remainder of 504.
The number 2 becomes the next digit in our result. 
Result so far: 90987.32
Subtracting 1906 from 2410 leaves us with 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

Step 11:
The number 953 fits into 5040 5 times, leaving a remainder of 275.
Record the quotient 5 as the next digit in the result. 
Result so far: 90987.325
Subtract 4765 from 5040 to get 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Let's proceed to step 12:
The number 953 fits into 2750 2 times, leaving a remainder of 844.
Write down 2 as next digit of the result. 
Result so far: 90987.3252
If we subtract 1906 from 2750, we get 844.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8440, and continue the process.

Advancing to step 13:
The number 953 fits into 8440 8 times, leaving a remainder of 816.
Put 8 as the next digit of the answer. 
Result so far: 90987.32528
If we take 7624 away from 8440, we end up with 816.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8160, and continue the process.

Moving on to step 14:
The number 953 fits into 8160 8 times, leaving a remainder of 536.
Put 8 as the next digit of the answer. 
Result so far: 90987.325288
If we subtract 7624 from 8160, we get 536.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5360, and continue the process.

The final outcome is 90987.325288, with a leftover of 5.36e-05.
