Let's divide 86427 by 78
We're looking to find how many times 78 goes into 86427.

On to step 1:
The number 78 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 78

Going ahead to step 2:
When dividing 86 by 78, we get 1 with a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 78 from 86 and we're left with 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 78

Advancing to step 3:
78 goes into 84 1 times with a remainder of 6.
The next digit of our result is 1. 
Result so far: 11.0
The remainder is 6 after subtracting 78 from 84.
Grab the next digit (2) from the dividend, add it to 6, then carry on: 62 / 78

Advancing to step 4:
If we divide 62 by 78, we get 0 and a remainder of 62.
Put 0 as the next digit of the answer. 
Result so far: 110.0
Subtract 0 from 62 to get 62.
Take the next digit (7) from the dividend and append it to 62, then repeat: 627 / 78

Step 5:
78 goes into 627 8 times with a remainder of 3.
Record the quotient 8 as the next digit in the result. 
Result so far: 1108.0
Deduct 624 from 627 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 6:
When dividing 30 by 78, we get 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 1108.0
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 7:
78 can be fit into 300 3 times, resulting in a remainder of 66.
Write down 3 as next digit of the result. 
Result so far: 1108.03
Subtracting 234 from 300 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Let's proceed to step 8:
The number 78 fits into 660 8 times, leaving a remainder of 36.
The number 8 becomes the next digit in our result. 
Result so far: 1108.038
The remainder is 36 after subtracting 624 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 9:
The number 78 fits into 360 4 times, leaving a remainder of 48.
Record the quotient 4 as the next digit in the result. 
Result so far: 1108.0384
Deduct 312 from 360 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 10:
The number 78 fits into 480 6 times, leaving a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 1108.03846
Subtracting 468 from 480 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 11:
78 goes into 120 1 times with a remainder of 42.
Write down 1 as next digit of the result. 
Result so far: 1108.038461
Subtracting 78 from 120 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 12:
78 goes into 420 5 times with a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 1108.0384615
Subtracting 390 from 420 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 13:
78 can be fit into 300 3 times, resulting in a remainder of 66.
Put 3 as the next digit of the answer. 
Result so far: 1108.03846153
Subtracting 234 from 300 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Our division results in 1108.03846153 with a remaining 6.6e-08.
