Let's divide 938723 by 78
We're looking to find how many times 78 goes into 938723.

Step 1:
9 divided by 78 is 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Include the next digit (3) from the dividend after 9, then repeat: 93 / 78

On to step 2:
When dividing 93 by 78, we get 1 with a remainder of 15.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 78 from 93 to get 15.
Grab the next digit (8) from the dividend, add it to 15, then carry on: 158 / 78

On to step 3:
If we divide 158 by 78, we get 2 and a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Deduct 156 from 158 and we're left with 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 78

Going ahead to step 4:
78 goes into 27 0 times with a remainder of 27.
The next digit of our result is 0. 
Result so far: 120.0
Subtracting 0 from 27 leaves us with 27.
Grab the next digit (2) from the dividend, add it to 27, then carry on: 272 / 78

On to step 5:
272 divided by 78 is 3 with a remainder of 38.
Record the quotient 3 as the next digit in the result. 
Result so far: 1203.0
Subtract 234 from 272 to get 38.
Append the next digit (3) from the dividend to 38 and continue with: 383 / 78

Advancing to step 6:
If we divide 383 by 78, we get 4 and a remainder of 71.
Use 4 as the next digit of our solution. 
Result so far: 12034.0
If we subtract 312 from 383, we get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Moving on to step 7:
78 can be fit into 710 9 times, resulting in a remainder of 8.
Put 9 as the next digit of the answer. 
Result so far: 12034.9
Deduct 702 from 710 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 8:
If we divide 80 by 78, we get 1 and a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 12034.91
If we subtract 78 from 80, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 9:
When dividing 20 by 78, we get 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 12034.91
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 10:
78 goes into 200 2 times with a remainder of 44.
Record the quotient 2 as the next digit in the result. 
Result so far: 12034.9102
Deduct 156 from 200 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 11:
78 can be fit into 440 5 times, resulting in a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 12034.91025
The remainder is 50 after subtracting 390 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 12:
The number 78 fits into 500 6 times, leaving a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 12034.910256
The remainder is 32 after subtracting 468 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 13:
When dividing 320 by 78, we get 4 with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 12034.9102564
Deduct 312 from 320 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 14:
When dividing 80 by 78, we get 1 with a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 12034.91025641
Subtract 78 from 80 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

After the division, we end up with 12034.91025641 and a remainder of 2e-09.
