We're dividing 749142 by 78 
We're looking to find how many times 78 goes into 749142.

Advancing to step 1:
When dividing 7 by 78, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 78

On to step 2:
78 can be fit into 74 0 times, resulting in a remainder of 74.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 74 leaves us with 74.
Bring next digit (9) of the dividend behind the 74 and repeat the process: 749 / 78

On to step 3:
749 divided by 78 is 9 with a remainder of 47.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtracting 702 from 749 leaves us with 47.
Bring next digit (1) of the dividend behind the 47 and repeat the process: 471 / 78

On to step 4:
If we divide 471 by 78, we get 6 and a remainder of 3.
Write down 6 as next digit of the result. 
Result so far: 96.0
Deduct 468 from 471 and we're left with 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 78

On to step 5:
If we divide 34 by 78, we get 0 and a remainder of 34.
The number 0 becomes the next digit in our result. 
Result so far: 960.0
Subtracting 0 from 34 leaves us with 34.
Append the next digit (2) from the dividend to 34 and continue with: 342 / 78

Let's proceed to step 6:
When dividing 342 by 78, we get 4 with a remainder of 30.
Write down 4 as next digit of the result. 
Result so far: 9604.0
Subtract 312 from 342 to get 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:
When dividing 300 by 78, we get 3 with a remainder of 66.
Put 3 as the next digit of the answer. 
Result so far: 9604.3
If we subtract 234 from 300, we get 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:
660 divided by 78 is 8 with a remainder of 36.
Write down 8 as next digit of the result. 
Result so far: 9604.38
Subtracting 624 from 660 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 9:
If we divide 360 by 78, we get 4 and a remainder of 48.
Write down 4 as next digit of the result. 
Result so far: 9604.384
Subtracting 312 from 360 leaves us 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:
78 can be fit into 480 6 times, resulting in a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 9604.3846
If we take 468 away from 480, we end up 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.

Step 11:
If we divide 120 by 78, we get 1 and a remainder of 42.
Put 1 as the next digit of the answer. 
Result so far: 9604.38461
If we subtract 78 from 120, we get 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:
When dividing 420 by 78, we get 5 with a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 9604.384615
Deduct 390 from 420 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.

Advancing to step 13:
When dividing 300 by 78, we get 3 with a remainder of 66.
The next digit of our result is 3. 
Result so far: 9604.3846153
If we take 234 away from 300, we end up 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.

On to step 14:
78 can be fit into 660 8 times, resulting in a remainder of 36.
Put 8 as the next digit of the answer. 
Result so far: 9604.38461538
If we subtract 624 from 660, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

The final result is 9604.38461538 with a remainder of 3.6e-08.
