99691515 ÷ 977 
We want to figure out the number of times 99691515 can be divided by 977.

Let's proceed to step 1:
977 goes into 9 0 times with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 977

On to step 2:
977 can be fit into 99 0 times, resulting in a remainder of 99.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 99 leaves us with 99.
Include the next digit (6) from the dividend after 99, then repeat: 996 / 977

Moving on to step 3:
The number 977 fits into 996 1 times, leaving a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 977 from 996 to get 19.
Include the next digit (9) from the dividend after 19, then repeat: 199 / 977

Going ahead to step 4:
977 can be fit into 199 0 times, resulting in a remainder of 199.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtracting 0 from 199 leaves us with 199.
Grab the next digit (1) from the dividend, add it to 199, then carry on: 1991 / 977

Going ahead to step 5:
If we divide 1991 by 977, we get 2 and a remainder of 37.
Use 2 as the next digit of our solution. 
Result so far: 102.0
Deduct 1954 from 1991 and we're left with 37.
Fetch the next digit (5) from the dividend, attach it to 37 and continue: 375 / 977

Going ahead to step 6:
977 goes into 375 0 times with a remainder of 375.
Put 0 as the next digit of the answer. 
Result so far: 1020.0
The remainder is 375 after subtracting 0 from 375.
Append the next digit (1) from the dividend to 375 and continue with: 3751 / 977

On to step 7:
If we divide 3751 by 977, we get 3 and a remainder of 820.
The number 3 becomes the next digit in our result. 
Result so far: 10203.0
The remainder is 820 after subtracting 2931 from 3751.
Grab the next digit (5) from the dividend, add it to 820, then carry on: 8205 / 977

On to step 8:
977 goes into 8205 8 times with a remainder of 389.
Record the quotient 8 as the next digit in the result. 
Result so far: 102038.0
Subtract 7816 from 8205 to get 389.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3890, and continue the process.

On to step 9:
When dividing 3890 by 977, we get 3 with a remainder of 959.
Put 3 as the next digit of the answer. 
Result so far: 102038.3
If we subtract 2931 from 3890, we get 959.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9590, and continue the process.

Going ahead to step 10:
9590 divided by 977 is 9 with a remainder of 797.
The next digit of our result is 9. 
Result so far: 102038.39
Subtracting 8793 from 9590 leaves us with 797.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7970, and continue the process.

Advancing to step 11:
If we divide 7970 by 977, we get 8 and a remainder of 154.
Use 8 as the next digit of our solution. 
Result so far: 102038.398
Subtracting 7816 from 7970 leaves us with 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Advancing to step 12:
If we divide 1540 by 977, we get 1 and a remainder of 563.
Record the quotient 1 as the next digit in the result. 
Result so far: 102038.3981
If we subtract 977 from 1540, we get 563.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5630, and continue the process.

Let's proceed to step 13:
977 goes into 5630 5 times with a remainder of 745.
Write down 5 as next digit of the result. 
Result so far: 102038.39815
Subtracting 4885 from 5630 leaves us with 745.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7450, and continue the process.

Let's proceed to step 14:
If we divide 7450 by 977, we get 7 and a remainder of 611.
Put 7 as the next digit of the answer. 
Result so far: 102038.398157
Subtract 6839 from 7450 to get 611.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6110, and continue the process.

Going ahead to step 15:
When dividing 6110 by 977, we get 6 with a remainder of 248.
The next digit of our result is 6. 
Result so far: 102038.3981576
If we subtract 5862 from 6110, we get 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Moving on to step 16:
When dividing 2480 by 977, we get 2 with a remainder of 526.
Put 2 as the next digit of the answer. 
Result so far: 102038.39815762
The remainder is 526 after subtracting 1954 from 2480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5260, and continue the process.

The quotient of the division is 102038.39815762, and the remainder is 5.26e-07.
