79997432 ÷ 977 
We want to divide 79997432 by 977.

On to step 1:
7 divided by 977 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 977

Advancing to step 2:
If we divide 79 by 977, we get 0 and a remainder of 79.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 79 and we're left with 79.
Append the next digit (9) from the dividend to 79 and continue with: 799 / 977

Let's proceed to step 3:
When dividing 799 by 977, we get 0 with a remainder of 799.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 799, we end up with 799.
Grab the next digit (9) from the dividend, add it to 799, then carry on: 7999 / 977

Moving on to step 4:
When dividing 7999 by 977, we get 8 with a remainder of 183.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we take 7816 away from 7999, we end up with 183.
Include the next digit (7) from the dividend after 183, then repeat: 1837 / 977

Step 5:
When dividing 1837 by 977, we get 1 with a remainder of 860.
The number 1 becomes the next digit in our result. 
Result so far: 81.0
If we take 977 away from 1837, we end up with 860.
Bring next digit (4) of the dividend behind the 860 and repeat the process: 8604 / 977

On to step 6:
977 goes into 8604 8 times with a remainder of 788.
The number 8 becomes the next digit in our result. 
Result so far: 818.0
If we take 7816 away from 8604, we end up with 788.
Grab the next digit (3) from the dividend, add it to 788, then carry on: 7883 / 977

Advancing to step 7:
The number 977 fits into 7883 8 times, leaving a remainder of 67.
Write down 8 as next digit of the result. 
Result so far: 8188.0
Deduct 7816 from 7883 and we're left with 67.
Fetch the next digit (2) from the dividend, attach it to 67 and continue: 672 / 977

Advancing to step 8:
977 goes into 672 0 times with a remainder of 672.
The next digit of our result is 0. 
Result so far: 81880.0
Deduct 0 from 672 and we're left with 672.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6720, and continue the process.

Let's proceed to step 9:
When dividing 6720 by 977, we get 6 with a remainder of 858.
The next digit of our result is 6. 
Result so far: 81880.6
If we take 5862 away from 6720, we end up with 858.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8580, and continue the process.

Step 10:
The number 977 fits into 8580 8 times, leaving a remainder of 764.
Put 8 as the next digit of the answer. 
Result so far: 81880.68
If we subtract 7816 from 8580, we get 764.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7640, and continue the process.

Going ahead to step 11:
7640 divided by 977 is 7 with a remainder of 801.
The next digit of our result is 7. 
Result so far: 81880.687
Deduct 6839 from 7640 and we're left with 801.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8010, and continue the process.

Moving on to step 12:
The number 977 fits into 8010 8 times, leaving a remainder of 194.
Put 8 as the next digit of the answer. 
Result so far: 81880.6878
The remainder is 194 after subtracting 7816 from 8010.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Let's proceed to step 13:
1940 divided by 977 is 1 with a remainder of 963.
Put 1 as the next digit of the answer. 
Result so far: 81880.68781
Subtract 977 from 1940 to get 963.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9630, and continue the process.

Step 14:
If we divide 9630 by 977, we get 9 and a remainder of 837.
Use 9 as the next digit of our solution. 
Result so far: 81880.687819
Subtracting 8793 from 9630 leaves us with 837.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8370, and continue the process.

Going ahead to step 15:
8370 divided by 977 is 8 with a remainder of 554.
Use 8 as the next digit of our solution. 
Result so far: 81880.6878198
If we subtract 7816 from 8370, we get 554.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5540, and continue the process.

Moving on to step 16:
If we divide 5540 by 977, we get 5 and a remainder of 655.
The next digit of our result is 5. 
Result so far: 81880.68781985
Subtract 4885 from 5540 to get 655.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6550, and continue the process.

The final outcome is 81880.68781985, with a leftover of 6.55e-07.
