745991 divided by 78 
Let's see how many times 78 fits into 745991.

Step 1:
If we divide 7 by 78, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 78

Moving on to step 2:
74 divided by 78 is 0 with a remainder of 74.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 74 leaves us with 74.
Bring next digit (5) of the dividend behind the 74 and repeat the process: 745 / 78

Going ahead to step 3:
78 can be fit into 745 9 times, resulting in 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.
Include the next digit (9) from the dividend after 43, then repeat: 439 / 78

Going ahead to step 4:
439 divided by 78 is 5 with a remainder of 49.
The number 5 becomes the next digit in our result. 
Result so far: 95.0
Deduct 390 from 439 and we're left with 49.
Grab the next digit (9) from the dividend, add it to 49, then carry on: 499 / 78

Going ahead to step 5:
78 goes into 499 6 times with a remainder of 31.
Put 6 as the next digit of the answer. 
Result so far: 956.0
Subtract 468 from 499 to get 31.
Include the next digit (1) from the dividend after 31, then repeat: 311 / 78

On to step 6:
78 can be fit into 311 3 times, resulting in a remainder of 77.
The next digit of our result is 3. 
Result so far: 9563.0
If we take 234 away from 311, we end up with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Moving on to step 7:
The number 78 fits into 770 9 times, leaving a remainder of 68.
Use 9 as the next digit of our solution. 
Result so far: 9563.9
Subtract 702 from 770 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 8:
680 divided by 78 is 8 with a remainder of 56.
Record the quotient 8 as the next digit in the result. 
Result so far: 9563.98
If we take 624 away from 680, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 9:
When dividing 560 by 78, we get 7 with a remainder of 14.
Write down 7 as next digit of the result. 
Result so far: 9563.987
Deduct 546 from 560 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 10:
If we divide 140 by 78, we get 1 and a remainder of 62.
Write down 1 as next digit of the result. 
Result so far: 9563.9871
Deduct 78 from 140 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 11:
78 goes into 620 7 times with a remainder of 74.
Put 7 as the next digit of the answer. 
Result so far: 9563.98717
Subtracting 546 from 620 leaves us with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Moving on to step 12:
When dividing 740 by 78, we get 9 with a remainder of 38.
The next digit of our result is 9. 
Result so far: 9563.987179
Subtract 702 from 740 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 13:
78 goes into 380 4 times with a remainder of 68.
Write down 4 as next digit of the result. 
Result so far: 9563.9871794
If we take 312 away from 380, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 14:
If we divide 680 by 78, we get 8 and a remainder of 56.
Write down 8 as next digit of the result. 
Result so far: 9563.98717948
The remainder is 56 after subtracting 624 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

After the division, we end up with 9563.98717948 and a remainder of 5.6e-08.
