We're dividing 74057951 by 78 
We want to figure out the number of times 74057951 can be divided by 78.

Step 1:
When dividing 7 by 78, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (4) of the dividend behind the 7 and repeat the process: 74 / 78

Going ahead to step 2:
The number 78 fits into 74 0 times, leaving a remainder of 74.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 74, we get 74.
Bring next digit (0) of the dividend behind the 74 and repeat the process: 740 / 78

Advancing to step 3:
When dividing 740 by 78, we get 9 with a remainder of 38.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we subtract 702 from 740, we get 38.
Fetch the next digit (5) from the dividend, attach it to 38 and continue: 385 / 78

On to step 4:
78 can be fit into 385 4 times, resulting in a remainder of 73.
Write down 4 as next digit of the result. 
Result so far: 94.0
Deduct 312 from 385 and we're left with 73.
Include the next digit (7) from the dividend after 73, then repeat: 737 / 78

Advancing to step 5:
If we divide 737 by 78, we get 9 and a remainder of 35.
Write down 9 as next digit of the result. 
Result so far: 949.0
If we subtract 702 from 737, we get 35.
Include the next digit (9) from the dividend after 35, then repeat: 359 / 78

Let's proceed to step 6:
The number 78 fits into 359 4 times, leaving a remainder of 47.
Use 4 as the next digit of our solution. 
Result so far: 9494.0
If we take 312 away from 359, we end up with 47.
Append the next digit (5) from the dividend to 47 and continue with: 475 / 78

Going ahead to step 7:
If we divide 475 by 78, we get 6 and a remainder of 7.
Write down 6 as next digit of the result. 
Result so far: 94946.0
Subtracting 468 from 475 leaves us with 7.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 78

Advancing to step 8:
The number 78 fits into 71 0 times, leaving a remainder of 71.
The number 0 becomes the next digit in our result. 
Result so far: 949460.0
Subtract 0 from 71 to 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 9:
The number 78 fits into 710 9 times, leaving a remainder of 8.
Write down 9 as next digit of the result. 
Result so far: 949460.9
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.

Going ahead to step 10:
If we divide 80 by 78, we get 1 and a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 949460.91
Subtracting 78 from 80 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 11:
78 can be fit into 20 0 times, resulting in a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 949460.91
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 12:
If we divide 200 by 78, we get 2 and a remainder of 44.
The number 2 becomes the next digit in our result. 
Result so far: 949460.9102
If we subtract 156 from 200, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 13:
78 can be fit into 440 5 times, resulting in a remainder of 50.
The next digit of our result is 5. 
Result so far: 949460.91025
Subtract 390 from 440 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 14:
The number 78 fits into 500 6 times, leaving a remainder of 32.
The number 6 becomes the next digit in our result. 
Result so far: 949460.910256
If we subtract 468 from 500, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 15:
320 divided by 78 is 4 with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 949460.9102564
Subtract 312 from 320 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 16:
80 divided by 78 is 1 with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 949460.91025641
If we take 78 away from 80, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final result is 949460.91025641 with a remainder of 2e-09.
