79571791 ÷ 678 
We're looking to find how many times 678 goes into 79571791.

Step 1:
7 divided by 678 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (9) from the dividend and append it to 7, then repeat: 79 / 678

Let's proceed to step 2:
678 can be fit into 79 0 times, resulting in a remainder of 79.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 79 to get 79.
Grab the next digit (5) from the dividend, add it to 79, then carry on: 795 / 678

Step 3:
The number 678 fits into 795 1 times, leaving a remainder of 117.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 678 from 795, we get 117.
Bring next digit (7) of the dividend behind the 117 and repeat the process: 1177 / 678

Advancing to step 4:
1177 divided by 678 is 1 with a remainder of 499.
Put 1 as the next digit of the answer. 
Result so far: 11.0
If we subtract 678 from 1177, we get 499.
Fetch the next digit (1) from the dividend, attach it to 499 and continue: 4991 / 678

Step 5:
678 can be fit into 4991 7 times, resulting in a remainder of 245.
The next digit of our result is 7. 
Result so far: 117.0
If we subtract 4746 from 4991, we get 245.
Grab the next digit (7) from the dividend, add it to 245, then carry on: 2457 / 678

Advancing to step 6:
The number 678 fits into 2457 3 times, leaving a remainder of 423.
The next digit of our result is 3. 
Result so far: 1173.0
Deduct 2034 from 2457 and we're left with 423.
Take the next digit (9) from the dividend and append it to 423, then repeat: 4239 / 678

Moving on to step 7:
4239 divided by 678 is 6 with a remainder of 171.
The next digit of our result is 6. 
Result so far: 11736.0
If we take 4068 away from 4239, we end up with 171.
Take the next digit (1) from the dividend and append it to 171, then repeat: 1711 / 678

Moving on to step 8:
When dividing 1711 by 678, we get 2 with a remainder of 355.
The number 2 becomes the next digit in our result. 
Result so far: 117362.0
If we take 1356 away from 1711, we end up with 355.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

Going ahead to step 9:
If we divide 3550 by 678, we get 5 and a remainder of 160.
Write down 5 as next digit of the result. 
Result so far: 117362.5
Subtract 3390 from 3550 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 10:
The number 678 fits into 1600 2 times, leaving a remainder of 244.
Use 2 as the next digit of our solution. 
Result so far: 117362.52
If we subtract 1356 from 1600, we get 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Step 11:
The number 678 fits into 2440 3 times, leaving a remainder of 406.
Use 3 as the next digit of our solution. 
Result so far: 117362.523
If we take 2034 away from 2440, we end up with 406.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

Going ahead to step 12:
The number 678 fits into 4060 5 times, leaving a remainder of 670.
The number 5 becomes the next digit in our result. 
Result so far: 117362.5235
If we take 3390 away from 4060, we end up with 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6700, and continue the process.

Step 13:
678 can be fit into 6700 9 times, resulting in a remainder of 598.
Use 9 as the next digit of our solution. 
Result so far: 117362.52359
The remainder is 598 after subtracting 6102 from 6700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5980, and continue the process.

Let's proceed to step 14:
When dividing 5980 by 678, we get 8 with a remainder of 556.
Record the quotient 8 as the next digit in the result. 
Result so far: 117362.523598
Subtracting 5424 from 5980 leaves us with 556.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5560, and continue the process.

Going ahead to step 15:
If we divide 5560 by 678, we get 8 and a remainder of 136.
The next digit of our result is 8. 
Result so far: 117362.5235988
Subtract 5424 from 5560 to get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

The final outcome is 117362.5235988, with a leftover of 1.36e-06.
