78556374 divided by 91 
Let's see how many times 91 fits into 78556374.

Let's proceed to step 1:
The number 91 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 91

On to step 2:
When dividing 78 by 91, we get 0 with a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 78 and we're left with 78.
Bring next digit (5) of the dividend behind the 78 and repeat the process: 785 / 91

Advancing to step 3:
When dividing 785 by 91, we get 8 with a remainder of 57.
Write down 8 as next digit of the result. 
Result so far: 8.0
Deduct 728 from 785 and we're left with 57.
Bring next digit (5) of the dividend behind the 57 and repeat the process: 575 / 91

Moving on to step 4:
91 goes into 575 6 times with a remainder of 29.
Write down 6 as next digit of the result. 
Result so far: 86.0
Subtracting 546 from 575 leaves us with 29.
Grab the next digit (6) from the dividend, add it to 29, then carry on: 296 / 91

Step 5:
When dividing 296 by 91, we get 3 with a remainder of 23.
The next digit of our result is 3. 
Result so far: 863.0
The remainder is 23 after subtracting 273 from 296.
Include the next digit (3) from the dividend after 23, then repeat: 233 / 91

Let's proceed to step 6:
91 goes into 233 2 times with a remainder of 51.
The next digit of our result is 2. 
Result so far: 8632.0
Subtracting 182 from 233 leaves us with 51.
Fetch the next digit (7) from the dividend, attach it to 51 and continue: 517 / 91

Advancing to step 7:
91 goes into 517 5 times with a remainder of 62.
The number 5 becomes the next digit in our result. 
Result so far: 86325.0
The remainder is 62 after subtracting 455 from 517.
Append the next digit (4) from the dividend to 62 and continue with: 624 / 91

On to step 8:
91 can be fit into 624 6 times, resulting in a remainder of 78.
Write down 6 as next digit of the result. 
Result so far: 863256.0
If we take 546 away from 624, we end up with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

On to step 9:
If we divide 780 by 91, we get 8 and a remainder of 52.
The number 8 becomes the next digit in our result. 
Result so far: 863256.8
If we subtract 728 from 780, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 10:
When dividing 520 by 91, we get 5 with a remainder of 65.
Record the quotient 5 as the next digit in the result. 
Result so far: 863256.85
If we take 455 away from 520, we end up 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.

On to step 11:
When dividing 650 by 91, we get 7 with a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 863256.857
The remainder is 13 after subtracting 637 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 12:
91 goes into 130 1 times with a remainder of 39.
Use 1 as the next digit of our solution. 
Result so far: 863256.8571
Deduct 91 from 130 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 13:
390 divided by 91 is 4 with a remainder of 26.
Record the quotient 4 as the next digit in the result. 
Result so far: 863256.85714
If we take 364 away from 390, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 14:
91 goes into 260 2 times with a remainder of 78.
The next digit of our result is 2. 
Result so far: 863256.857142
The remainder is 78 after subtracting 182 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

On to step 15:
91 goes into 780 8 times with a remainder of 52.
Put 8 as the next digit of the answer. 
Result so far: 863256.8571428
The remainder is 52 after subtracting 728 from 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 16:
520 divided by 91 is 5 with a remainder of 65.
Put 5 as the next digit of the answer. 
Result so far: 863256.85714285
Subtract 455 from 520 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

After the division, we end up with 863256.85714285 and a remainder of 6.5e-08.
