99960408 ÷ 107 
We want to divide 99960408 by 107.

Let's proceed to step 1:
107 goes into 9 0 times with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 107

Advancing to step 2:
107 goes into 99 0 times with a remainder of 99.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 99, we get 99.
Append the next digit (9) from the dividend to 99 and continue with: 999 / 107

On to step 3:
107 can be fit into 999 9 times, resulting in a remainder of 36.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtract 963 from 999 to get 36.
Append the next digit (6) from the dividend to 36 and continue with: 366 / 107

Advancing to step 4:
107 goes into 366 3 times with a remainder of 45.
The number 3 becomes the next digit in our result. 
Result so far: 93.0
Deduct 321 from 366 and we're left with 45.
Append the next digit (0) from the dividend to 45 and continue with: 450 / 107

Going ahead to step 5:
If we divide 450 by 107, we get 4 and a remainder of 22.
The next digit of our result is 4. 
Result so far: 934.0
If we take 428 away from 450, we end up with 22.
Include the next digit (4) from the dividend after 22, then repeat: 224 / 107

On to step 6:
The number 107 fits into 224 2 times, leaving a remainder of 10.
Use 2 as the next digit of our solution. 
Result so far: 9342.0
Subtracting 214 from 224 leaves us with 10.
Take the next digit (0) from the dividend and append it to 10, then repeat: 100 / 107

Moving on to step 7:
The number 107 fits into 100 0 times, leaving a remainder of 100.
Write down 0 as next digit of the result. 
Result so far: 93420.0
If we subtract 0 from 100, we get 100.
Take the next digit (8) from the dividend and append it to 100, then repeat: 1008 / 107

Let's proceed to step 8:
If we divide 1008 by 107, we get 9 and a remainder of 45.
The next digit of our result is 9. 
Result so far: 934209.0
Deduct 963 from 1008 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 9:
When dividing 450 by 107, we get 4 with a remainder of 22.
Write down 4 as next digit of the result. 
Result so far: 934209.4
Deduct 428 from 450 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 10:
The number 107 fits into 220 2 times, leaving a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 934209.42
If we take 214 away from 220, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 11:
The number 107 fits into 60 0 times, leaving a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 934209.42
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 12:
When dividing 600 by 107, we get 5 with a remainder of 65.
Use 5 as the next digit of our solution. 
Result so far: 934209.4205
Deduct 535 from 600 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Going ahead to step 13:
107 goes into 650 6 times with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 934209.42056
Deduct 642 from 650 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 14:
If we divide 80 by 107, we get 0 and a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 934209.42056
Subtract 0 from 80 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 15:
The number 107 fits into 800 7 times, leaving a remainder of 51.
Use 7 as the next digit of our solution. 
Result so far: 934209.4205607
If we take 749 away from 800, we end up with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Moving on to step 16:
When dividing 510 by 107, we get 4 with a remainder of 82.
Use 4 as the next digit of our solution. 
Result so far: 934209.42056074
If we take 428 away from 510, we end up with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

After the division, we end up with 934209.42056074 and a remainder of 8.2e-08.
