Let's divide 745438 by 78
We want to figure out the number of times 745438 can be divided by 78.

Moving on to step 1:
If we divide 7 by 78, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 78

Going ahead to step 2:
The number 78 fits into 74 0 times, leaving a remainder of 74.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 74 and we're left with 74.
Include the next digit (5) from the dividend after 74, then repeat: 745 / 78

Going ahead to step 3:
When dividing 745 by 78, we get 9 with a remainder of 43.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we take 702 away from 745, we end up with 43.
Take the next digit (4) from the dividend and append it to 43, then repeat: 434 / 78

Step 4:
If we divide 434 by 78, we get 5 and a remainder of 44.
The number 5 becomes the next digit in our result. 
Result so far: 95.0
Deduct 390 from 434 and we're left with 44.
Grab the next digit (3) from the dividend, add it to 44, then carry on: 443 / 78

Step 5:
78 can be fit into 443 5 times, resulting in a remainder of 53.
The number 5 becomes the next digit in our result. 
Result so far: 955.0
If we subtract 390 from 443, we get 53.
Fetch the next digit (8) from the dividend, attach it to 53 and continue: 538 / 78

Step 6:
If we divide 538 by 78, we get 6 and a remainder of 70.
Put 6 as the next digit of the answer. 
Result so far: 9556.0
Subtracting 468 from 538 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 7:
The number 78 fits into 700 8 times, leaving a remainder of 76.
Record the quotient 8 as the next digit in the result. 
Result so far: 9556.8
Subtract 624 from 700 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 8:
When dividing 760 by 78, we get 9 with a remainder of 58.
The next digit of our result is 9. 
Result so far: 9556.89
If we take 702 away from 760, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 9:
580 divided by 78 is 7 with a remainder of 34.
Write down 7 as next digit of the result. 
Result so far: 9556.897
Subtracting 546 from 580 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 10:
340 divided by 78 is 4 with a remainder of 28.
The number 4 becomes the next digit in our result. 
Result so far: 9556.8974
Subtracting 312 from 340 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 11:
78 can be fit into 280 3 times, resulting in a remainder of 46.
Put 3 as the next digit of the answer. 
Result so far: 9556.89743
The remainder is 46 after subtracting 234 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 12:
78 goes into 460 5 times with a remainder of 70.
Put 5 as the next digit of the answer. 
Result so far: 9556.897435
Subtract 390 from 460 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 13:
When dividing 700 by 78, we get 8 with a remainder of 76.
Record the quotient 8 as the next digit in the result. 
Result so far: 9556.8974358
If we subtract 624 from 700, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 14:
78 goes into 760 9 times with a remainder of 58.
The number 9 becomes the next digit in our result. 
Result so far: 9556.89743589
If we take 702 away from 760, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

After the division, we end up with 9556.89743589 and a remainder of 5.8e-08.
