We look at the division of 77099679 by 907 
We're looking to find how many times 907 goes into 77099679.

Step 1:
If we divide 7 by 907, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
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 / 907

Advancing to step 2:
If we divide 77 by 907, we get 0 and a remainder of 77.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 77, we end up with 77.
Include the next digit (0) from the dividend after 77, then repeat: 770 / 907

Let's proceed to step 3:
770 divided by 907 is 0 with a remainder of 770.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 770 and we're left with 770.
Fetch the next digit (9) from the dividend, attach it to 770 and continue: 7709 / 907

Advancing to step 4:
7709 divided by 907 is 8 with a remainder of 453.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtract 7256 from 7709 to get 453.
Grab the next digit (9) from the dividend, add it to 453, then carry on: 4539 / 907

Step 5:
4539 divided by 907 is 5 with a remainder of 4.
Use 5 as the next digit of our solution. 
Result so far: 85.0
Subtracting 4535 from 4539 leaves us with 4.
Take the next digit (6) from the dividend and append it to 4, then repeat: 46 / 907

Going ahead to step 6:
When dividing 46 by 907, we get 0 with a remainder of 46.
The next digit of our result is 0. 
Result so far: 850.0
The remainder is 46 after subtracting 0 from 46.
Fetch the next digit (7) from the dividend, attach it to 46 and continue: 467 / 907

On to step 7:
When dividing 467 by 907, we get 0 with a remainder of 467.
The number 0 becomes the next digit in our result. 
Result so far: 8500.0
Deduct 0 from 467 and we're left with 467.
Fetch the next digit (9) from the dividend, attach it to 467 and continue: 4679 / 907

On to step 8:
The number 907 fits into 4679 5 times, leaving a remainder of 144.
The number 5 becomes the next digit in our result. 
Result so far: 85005.0
If we subtract 4535 from 4679, we get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Advancing to step 9:
907 can be fit into 1440 1 times, resulting in a remainder of 533.
Use 1 as the next digit of our solution. 
Result so far: 85005.1
Deduct 907 from 1440 and we're left with 533.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5330, and continue the process.

Moving on to step 10:
The number 907 fits into 5330 5 times, leaving a remainder of 795.
The number 5 becomes the next digit in our result. 
Result so far: 85005.15
Deduct 4535 from 5330 and we're left with 795.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7950, and continue the process.

Let's proceed to step 11:
7950 divided by 907 is 8 with a remainder of 694.
Write down 8 as next digit of the result. 
Result so far: 85005.158
Deduct 7256 from 7950 and we're left with 694.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6940, and continue the process.

Advancing to step 12:
The number 907 fits into 6940 7 times, leaving a remainder of 591.
The number 7 becomes the next digit in our result. 
Result so far: 85005.1587
If we take 6349 away from 6940, we end up with 591.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5910, and continue the process.

Step 13:
5910 divided by 907 is 6 with a remainder of 468.
Put 6 as the next digit of the answer. 
Result so far: 85005.15876
The remainder is 468 after subtracting 5442 from 5910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

Let's proceed to step 14:
907 can be fit into 4680 5 times, resulting in a remainder of 145.
The next digit of our result is 5. 
Result so far: 85005.158765
If we subtract 4535 from 4680, we get 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Going ahead to step 15:
907 goes into 1450 1 times with a remainder of 543.
Record the quotient 1 as the next digit in the result. 
Result so far: 85005.1587651
If we take 907 away from 1450, we end up with 543.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5430, and continue the process.

Going ahead to step 16:
The number 907 fits into 5430 5 times, leaving a remainder of 895.
The next digit of our result is 5. 
Result so far: 85005.15876515
Deduct 4535 from 5430 and we're left with 895.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8950, and continue the process.

The final outcome is 85005.15876515, with a leftover of 8.95e-07.
