We look at the division of 909691 by 78 
We want to divide 909691 by 78.

Advancing to step 1:
78 goes into 9 0 times with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 78

On to step 2:
The number 78 fits into 90 1 times, leaving a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 78 from 90 to get 12.
Append the next digit (9) from the dividend to 12 and continue with: 129 / 78

Step 3:
When dividing 129 by 78, we get 1 with a remainder of 51.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Subtracting 78 from 129 leaves us with 51.
Fetch the next digit (6) from the dividend, attach it to 51 and continue: 516 / 78

Advancing to step 4:
If we divide 516 by 78, we get 6 and a remainder of 48.
Record the quotient 6 as the next digit in the result. 
Result so far: 116.0
If we subtract 468 from 516, we get 48.
Take the next digit (9) from the dividend and append it to 48, then repeat: 489 / 78

On to step 5:
78 can be fit into 489 6 times, resulting in a remainder of 21.
The number 6 becomes the next digit in our result. 
Result so far: 1166.0
If we take 468 away from 489, we end up with 21.
Grab the next digit (1) from the dividend, add it to 21, then carry on: 211 / 78

On to step 6:
If we divide 211 by 78, we get 2 and a remainder of 55.
The number 2 becomes the next digit in our result. 
Result so far: 11662.0
The remainder is 55 after subtracting 156 from 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

On to step 7:
78 goes into 550 7 times with a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 11662.7
If we take 546 away from 550, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 8:
The number 78 fits into 40 0 times, leaving a remainder of 40.
The next digit of our result is 0. 
Result so far: 11662.7
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 9:
If we divide 400 by 78, we get 5 and a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 11662.705
The remainder is 10 after subtracting 390 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 10:
78 goes into 100 1 times with a remainder of 22.
Write down 1 as next digit of the result. 
Result so far: 11662.7051
If we subtract 78 from 100, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 11:
When dividing 220 by 78, we get 2 with a remainder of 64.
Use 2 as the next digit of our solution. 
Result so far: 11662.70512
If we subtract 156 from 220, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 12:
78 can be fit into 640 8 times, resulting in a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 11662.705128
If we subtract 624 from 640, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 13:
78 goes into 160 2 times with a remainder of 4.
The next digit of our result is 2. 
Result so far: 11662.7051282
If we take 156 away from 160, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 14:
78 can be fit into 40 0 times, resulting in a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 11662.7051282
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The quotient of the division is 11662.7051282, and the remainder is 4e-08.
