79661721 ÷ 979 
We're looking to find how many times 979 goes into 79661721.

Going ahead to step 1:
979 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (9) from the dividend after 7, then repeat: 79 / 979

Going ahead to step 2:
The number 979 fits into 79 0 times, leaving a remainder of 79.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 79, we get 79.
Append the next digit (6) from the dividend to 79 and continue with: 796 / 979

Advancing to step 3:
979 goes into 796 0 times with a remainder of 796.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 796 after subtracting 0 from 796.
Include the next digit (6) from the dividend after 796, then repeat: 7966 / 979

Moving on to step 4:
979 goes into 7966 8 times with a remainder of 134.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Deduct 7832 from 7966 and we're left with 134.
Bring next digit (1) of the dividend behind the 134 and repeat the process: 1341 / 979

Moving on to step 5:
When dividing 1341 by 979, we get 1 with a remainder of 362.
Put 1 as the next digit of the answer. 
Result so far: 81.0
Subtracting 979 from 1341 leaves us with 362.
Fetch the next digit (7) from the dividend, attach it to 362 and continue: 3627 / 979

On to step 6:
979 goes into 3627 3 times with a remainder of 690.
Put 3 as the next digit of the answer. 
Result so far: 813.0
Subtracting 2937 from 3627 leaves us with 690.
Take the next digit (2) from the dividend and append it to 690, then repeat: 6902 / 979

Advancing to step 7:
979 can be fit into 6902 7 times, resulting in a remainder of 49.
Record the quotient 7 as the next digit in the result. 
Result so far: 8137.0
Subtracting 6853 from 6902 leaves us with 49.
Append the next digit (1) from the dividend to 49 and continue with: 491 / 979

Moving on to step 8:
979 goes into 491 0 times with a remainder of 491.
Record the quotient 0 as the next digit in the result. 
Result so far: 81370.0
If we subtract 0 from 491, we get 491.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4910, and continue the process.

Step 9:
979 goes into 4910 5 times with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 81370.5
The remainder is 15 after subtracting 4895 from 4910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 10:
150 divided by 979 is 0 with a remainder of 150.
The next digit of our result is 0. 
Result so far: 81370.5
Subtract 0 from 150 to get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Let's proceed to step 11:
979 goes into 1500 1 times with a remainder of 521.
Use 1 as the next digit of our solution. 
Result so far: 81370.501
If we subtract 979 from 1500, we get 521.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5210, and continue the process.

Advancing to step 12:
979 can be fit into 5210 5 times, resulting in a remainder of 315.
The next digit of our result is 5. 
Result so far: 81370.5015
The remainder is 315 after subtracting 4895 from 5210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

Moving on to step 13:
979 can be fit into 3150 3 times, resulting in a remainder of 213.
Put 3 as the next digit of the answer. 
Result so far: 81370.50153
Deduct 2937 from 3150 and we're left with 213.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2130, and continue the process.

Let's proceed to step 14:
979 goes into 2130 2 times with a remainder of 172.
Record the quotient 2 as the next digit in the result. 
Result so far: 81370.501532
Subtracting 1958 from 2130 leaves us with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Let's proceed to step 15:
1720 divided by 979 is 1 with a remainder of 741.
Use 1 as the next digit of our solution. 
Result so far: 81370.5015321
If we take 979 away from 1720, we end up with 741.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7410, and continue the process.

Going ahead to step 16:
7410 divided by 979 is 7 with a remainder of 557.
Put 7 as the next digit of the answer. 
Result so far: 81370.50153217
The remainder is 557 after subtracting 6853 from 7410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5570, and continue the process.

The final outcome is 81370.50153217, with a leftover of 5.57e-07.
