Let's divide 99170921 by 979
We want to figure out the number of times 99170921 can be divided by 979.

Going ahead to step 1:
When dividing 9 by 979, we get 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 979

Step 2:
979 can be fit into 99 0 times, resulting in a remainder of 99.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 99 to get 99.
Append the next digit (1) from the dividend to 99 and continue with: 991 / 979

Advancing to step 3:
When dividing 991 by 979, we get 1 with a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 979 from 991 to get 12.
Bring next digit (7) of the dividend behind the 12 and repeat the process: 127 / 979

Advancing to step 4:
If we divide 127 by 979, we get 0 and a remainder of 127.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtract 0 from 127 to get 127.
Grab the next digit (0) from the dividend, add it to 127, then carry on: 1270 / 979

Step 5:
1270 divided by 979 is 1 with a remainder of 291.
Record the quotient 1 as the next digit in the result. 
Result so far: 101.0
Subtracting 979 from 1270 leaves us with 291.
Grab the next digit (9) from the dividend, add it to 291, then carry on: 2919 / 979

Let's proceed to step 6:
2919 divided by 979 is 2 with a remainder of 961.
Use 2 as the next digit of our solution. 
Result so far: 1012.0
If we subtract 1958 from 2919, we get 961.
Include the next digit (2) from the dividend after 961, then repeat: 9612 / 979

Let's proceed to step 7:
9612 divided by 979 is 9 with a remainder of 801.
Put 9 as the next digit of the answer. 
Result so far: 10129.0
Deduct 8811 from 9612 and we're left with 801.
Fetch the next digit (1) from the dividend, attach it to 801 and continue: 8011 / 979

Let's proceed to step 8:
979 can be fit into 8011 8 times, resulting in a remainder of 179.
Use 8 as the next digit of our solution. 
Result so far: 101298.0
If we subtract 7832 from 8011, we get 179.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

Moving on to step 9:
If we divide 1790 by 979, we get 1 and a remainder of 811.
Record the quotient 1 as the next digit in the result. 
Result so far: 101298.1
If we take 979 away from 1790, we end up with 811.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8110, and continue the process.

Step 10:
8110 divided by 979 is 8 with a remainder of 278.
Record the quotient 8 as the next digit in the result. 
Result so far: 101298.18
Deduct 7832 from 8110 and we're left with 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

Advancing to step 11:
The number 979 fits into 2780 2 times, leaving a remainder of 822.
Write down 2 as next digit of the result. 
Result so far: 101298.182
Subtract 1958 from 2780 to get 822.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8220, and continue the process.

Step 12:
8220 divided by 979 is 8 with a remainder of 388.
Write down 8 as next digit of the result. 
Result so far: 101298.1828
If we take 7832 away from 8220, we end up with 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Going ahead to step 13:
979 can be fit into 3880 3 times, resulting in a remainder of 943.
Write down 3 as next digit of the result. 
Result so far: 101298.18283
If we subtract 2937 from 3880, we get 943.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9430, and continue the process.

Going ahead to step 14:
9430 divided by 979 is 9 with a remainder of 619.
Put 9 as the next digit of the answer. 
Result so far: 101298.182839
If we take 8811 away from 9430, we end up with 619.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6190, and continue the process.

Let's proceed to step 15:
979 can be fit into 6190 6 times, resulting in a remainder of 316.
The number 6 becomes the next digit in our result. 
Result so far: 101298.1828396
If we take 5874 away from 6190, we end up with 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

Step 16:
3160 divided by 979 is 3 with a remainder of 223.
Record the quotient 3 as the next digit in the result. 
Result so far: 101298.18283963
Subtract 2937 from 3160 to get 223.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2230, and continue the process.

Our division results in 101298.18283963 with a remaining 2.23e-07.
