7944678 ÷ 91 
We're looking to find how many times 91 goes into 7944678.

On to step 1:
If we divide 7 by 91, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (9) from the dividend after 7, then repeat: 79 / 91

On to step 2:
91 can be fit into 79 0 times, resulting in a remainder of 79.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 79, we end up with 79.
Include the next digit (4) from the dividend after 79, then repeat: 794 / 91

Advancing to step 3:
If we divide 794 by 91, we get 8 and a remainder of 66.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtracting 728 from 794 leaves us with 66.
Fetch the next digit (4) from the dividend, attach it to 66 and continue: 664 / 91

Moving on to step 4:
The number 91 fits into 664 7 times, leaving a remainder of 27.
Record the quotient 7 as the next digit in the result. 
Result so far: 87.0
If we subtract 637 from 664, we get 27.
Append the next digit (6) from the dividend to 27 and continue with: 276 / 91

Advancing to step 5:
The number 91 fits into 276 3 times, leaving a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 873.0
The remainder is 3 after subtracting 273 from 276.
Grab the next digit (7) from the dividend, add it to 3, then carry on: 37 / 91

Moving on to step 6:
37 divided by 91 is 0 with a remainder of 37.
The next digit of our result is 0. 
Result so far: 8730.0
If we take 0 away from 37, we end up with 37.
Take the next digit (8) from the dividend and append it to 37, then repeat: 378 / 91

On to step 7:
91 goes into 378 4 times with a remainder of 14.
The number 4 becomes the next digit in our result. 
Result so far: 87304.0
Deduct 364 from 378 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 8:
91 goes into 140 1 times with a remainder of 49.
The next digit of our result is 1. 
Result so far: 87304.1
Deduct 91 from 140 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 9:
91 goes into 490 5 times with a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 87304.15
The remainder is 35 after subtracting 455 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 10:
350 divided by 91 is 3 with a remainder of 77.
The next digit of our result is 3. 
Result so far: 87304.153
If we subtract 273 from 350, we get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

On to step 11:
91 can be fit into 770 8 times, resulting in a remainder of 42.
The number 8 becomes the next digit in our result. 
Result so far: 87304.1538
The remainder is 42 after subtracting 728 from 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 12:
The number 91 fits into 420 4 times, leaving a remainder of 56.
The next digit of our result is 4. 
Result so far: 87304.15384
Subtracting 364 from 420 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 13:
When dividing 560 by 91, we get 6 with a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 87304.153846
The remainder is 14 after subtracting 546 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 14:
If we divide 140 by 91, we get 1 and a remainder of 49.
Put 1 as the next digit of the answer. 
Result so far: 87304.1538461
Subtract 91 from 140 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Moving on to step 15:
When dividing 490 by 91, we get 5 with a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 87304.15384615
Subtract 455 from 490 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The final outcome is 87304.15384615, with a leftover of 3.5e-08.
