83739 ÷ 78 
We want to divide 83739 by 78.

On to step 1:
The number 78 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 78

Step 2:
The number 78 fits into 83 1 times, leaving a remainder of 5.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 78 from 83, we get 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 78

Let's proceed to step 3:
The number 78 fits into 57 0 times, leaving a remainder of 57.
The next digit of our result is 0. 
Result so far: 10.0
Deduct 0 from 57 and we're left with 57.
Bring next digit (3) of the dividend behind the 57 and repeat the process: 573 / 78

On to step 4:
78 goes into 573 7 times with a remainder of 27.
The next digit of our result is 7. 
Result so far: 107.0
Subtract 546 from 573 to get 27.
Take the next digit (9) from the dividend and append it to 27, then repeat: 279 / 78

Advancing to step 5:
78 can be fit into 279 3 times, resulting in a remainder of 45.
The number 3 becomes the next digit in our result. 
Result so far: 1073.0
The remainder is 45 after subtracting 234 from 279.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 6:
When dividing 450 by 78, we get 5 with a remainder of 60.
Use 5 as the next digit of our solution. 
Result so far: 1073.5
If we take 390 away from 450, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 7:
78 can be fit into 600 7 times, resulting in a remainder of 54.
The number 7 becomes the next digit in our result. 
Result so far: 1073.57
Deduct 546 from 600 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 8:
78 goes into 540 6 times with a remainder of 72.
The next digit of our result is 6. 
Result so far: 1073.576
The remainder is 72 after subtracting 468 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 9:
78 goes into 720 9 times with a remainder of 18.
Record the quotient 9 as the next digit in the result. 
Result so far: 1073.5769
The remainder is 18 after subtracting 702 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 10:
78 goes into 180 2 times with a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 1073.57692
If we take 156 away from 180, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 11:
If we divide 240 by 78, we get 3 and a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 1073.576923
If we subtract 234 from 240, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 12:
60 divided by 78 is 0 with a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 1073.576923
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 13:
When dividing 600 by 78, we get 7 with a remainder of 54.
The number 7 becomes the next digit in our result. 
Result so far: 1073.57692307
Subtracting 546 from 600 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

The final result is 1073.57692307 with a remainder of 5.4e-08.
