Let's divide 77901609 by 107
We want to divide 77901609 by 107.

Going ahead to step 1:
7 divided by 107 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 107

On to step 2:
If we divide 77 by 107, we get 0 and a remainder of 77.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 77 and we're left with 77.
Grab the next digit (9) from the dividend, add it to 77, then carry on: 779 / 107

Going ahead to step 3:
107 goes into 779 7 times with a remainder of 30.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we take 749 away from 779, we end up with 30.
Grab the next digit (0) from the dividend, add it to 30, then carry on: 300 / 107

Advancing to step 4:
107 can be fit into 300 2 times, resulting in a remainder of 86.
The next digit of our result is 2. 
Result so far: 72.0
Subtracting 214 from 300 leaves us with 86.
Append the next digit (1) from the dividend to 86 and continue with: 861 / 107

On to step 5:
107 can be fit into 861 8 times, resulting in a remainder of 5.
The next digit of our result is 8. 
Result so far: 728.0
If we take 856 away from 861, we end up with 5.
Bring next digit (6) of the dividend behind the 5 and repeat the process: 56 / 107

Advancing to step 6:
When dividing 56 by 107, we get 0 with a remainder of 56.
Write down 0 as next digit of the result. 
Result so far: 7280.0
If we subtract 0 from 56, we get 56.
Grab the next digit (0) from the dividend, add it to 56, then carry on: 560 / 107

Going ahead to step 7:
If we divide 560 by 107, we get 5 and a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 72805.0
Deduct 535 from 560 and we're left with 25.
Take the next digit (9) from the dividend and append it to 25, then repeat: 259 / 107

On to step 8:
When dividing 259 by 107, we get 2 with a remainder of 45.
Write down 2 as next digit of the result. 
Result so far: 728052.0
Subtracting 214 from 259 leaves us 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.

Moving on to step 9:
107 goes into 450 4 times with a remainder of 22.
Write down 4 as next digit of the result. 
Result so far: 728052.4
Subtracting 428 from 450 leaves us 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.

Advancing to step 10:
107 goes into 220 2 times with a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 728052.42
If we subtract 214 from 220, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 11:
The number 107 fits into 60 0 times, leaving a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 728052.42
Subtract 0 from 60 to 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.

Going ahead to step 12:
The number 107 fits into 600 5 times, leaving a remainder of 65.
Put 5 as the next digit of the answer. 
Result so far: 728052.4205
The remainder is 65 after subtracting 535 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Step 13:
The number 107 fits into 650 6 times, leaving a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 728052.42056
Subtracting 642 from 650 leaves us 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:
When dividing 80 by 107, we get 0 with a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 728052.42056
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 15:
107 can be fit into 800 7 times, resulting in a remainder of 51.
Use 7 as the next digit of our solution. 
Result so far: 728052.4205607
Subtract 749 from 800 to get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Advancing to step 16:
When dividing 510 by 107, we get 4 with a remainder of 82.
The number 4 becomes the next digit in our result. 
Result so far: 728052.42056074
Subtracting 428 from 510 leaves us 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.

The final outcome is 728052.42056074, with a leftover of 8.2e-08.
