We're dividing 684378 by 91 
Let's see how many times 91 fits into 684378.

Going ahead to step 1:
91 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 91

Advancing to step 2:
The number 91 fits into 68 0 times, leaving a remainder of 68.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 68 to get 68.
Include the next digit (4) from the dividend after 68, then repeat: 684 / 91

Advancing to step 3:
The number 91 fits into 684 7 times, leaving a remainder of 47.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we take 637 away from 684, we end up with 47.
Fetch the next digit (3) from the dividend, attach it to 47 and continue: 473 / 91

On to step 4:
If we divide 473 by 91, we get 5 and a remainder of 18.
The next digit of our result is 5. 
Result so far: 75.0
Subtract 455 from 473 to get 18.
Grab the next digit (7) from the dividend, add it to 18, then carry on: 187 / 91

Going ahead to step 5:
If we divide 187 by 91, we get 2 and a remainder of 5.
The number 2 becomes the next digit in our result. 
Result so far: 752.0
The remainder is 5 after subtracting 182 from 187.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 91

On to step 6:
If we divide 58 by 91, we get 0 and a remainder of 58.
Record the quotient 0 as the next digit in the result. 
Result so far: 7520.0
The remainder is 58 after subtracting 0 from 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 7:
The number 91 fits into 580 6 times, leaving a remainder of 34.
Write down 6 as next digit of the result. 
Result so far: 7520.6
The remainder is 34 after subtracting 546 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 8:
When dividing 340 by 91, we get 3 with a remainder of 67.
The next digit of our result is 3. 
Result so far: 7520.63
Subtract 273 from 340 to get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Advancing to step 9:
If we divide 670 by 91, we get 7 and a remainder of 33.
Write down 7 as next digit of the result. 
Result so far: 7520.637
The remainder is 33 after subtracting 637 from 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 10:
The number 91 fits into 330 3 times, leaving a remainder of 57.
Record the quotient 3 as the next digit in the result. 
Result so far: 7520.6373
If we take 273 away from 330, we end up with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

On to step 11:
If we divide 570 by 91, we get 6 and a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 7520.63736
Subtract 546 from 570 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 12:
When dividing 240 by 91, we get 2 with a remainder of 58.
Record the quotient 2 as the next digit in the result. 
Result so far: 7520.637362
Subtracting 182 from 240 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 13:
580 divided by 91 is 6 with a remainder of 34.
Write down 6 as next digit of the result. 
Result so far: 7520.6373626
Subtract 546 from 580 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 14:
91 can be fit into 340 3 times, resulting in a remainder of 67.
Put 3 as the next digit of the answer. 
Result so far: 7520.63736263
Deduct 273 from 340 and we're left with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

The quotient of the division is 7520.63736263, and the remainder is 6.7e-08.
