78357680 ÷ 790 
We're looking to find how many times 790 goes into 78357680.

Going ahead to step 1:
7 divided by 790 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 790

Step 2:
The number 790 fits into 78 0 times, leaving a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Append the next digit (3) from the dividend to 78 and continue with: 783 / 790

Advancing to step 3:
If we divide 783 by 790, we get 0 and a remainder of 783.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 783 and we're left with 783.
Fetch the next digit (5) from the dividend, attach it to 783 and continue: 7835 / 790

Let's proceed to step 4:
790 can be fit into 7835 9 times, resulting in a remainder of 725.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
The remainder is 725 after subtracting 7110 from 7835.
Take the next digit (7) from the dividend and append it to 725, then repeat: 7257 / 790

Advancing to step 5:
The number 790 fits into 7257 9 times, leaving a remainder of 147.
Write down 9 as next digit of the result. 
Result so far: 99.0
If we take 7110 away from 7257, we end up with 147.
Fetch the next digit (6) from the dividend, attach it to 147 and continue: 1476 / 790

On to step 6:
When dividing 1476 by 790, we get 1 with a remainder of 686.
The next digit of our result is 1. 
Result so far: 991.0
Subtracting 790 from 1476 leaves us with 686.
Fetch the next digit (8) from the dividend, attach it to 686 and continue: 6868 / 790

Step 7:
790 goes into 6868 8 times with a remainder of 548.
The number 8 becomes the next digit in our result. 
Result so far: 9918.0
If we take 6320 away from 6868, we end up with 548.
Fetch the next digit (0) from the dividend, attach it to 548 and continue: 5480 / 790

On to step 8:
5480 divided by 790 is 6 with a remainder of 740.
Use 6 as the next digit of our solution. 
Result so far: 99186.0
The remainder is 740 after subtracting 4740 from 5480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7400, and continue the process.

Advancing to step 9:
790 goes into 7400 9 times with a remainder of 290.
The next digit of our result is 9. 
Result so far: 99186.9
Subtracting 7110 from 7400 leaves us with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Step 10:
2900 divided by 790 is 3 with a remainder of 530.
Use 3 as the next digit of our solution. 
Result so far: 99186.93
Subtracting 2370 from 2900 leaves us with 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

Advancing to step 11:
If we divide 5300 by 790, we get 6 and a remainder of 560.
The number 6 becomes the next digit in our result. 
Result so far: 99186.936
If we subtract 4740 from 5300, we get 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Step 12:
790 goes into 5600 7 times with a remainder of 70.
Use 7 as the next digit of our solution. 
Result so far: 99186.9367
Deduct 5530 from 5600 and we're left 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.

Step 13:
If we divide 700 by 790, we get 0 and a remainder of 700.
Use 0 as the next digit of our solution. 
Result so far: 99186.9367
Subtract 0 from 700 to get 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Advancing to step 14:
790 can be fit into 7000 8 times, resulting in a remainder of 680.
Use 8 as the next digit of our solution. 
Result so far: 99186.936708
Subtracting 6320 from 7000 leaves us with 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Let's proceed to step 15:
790 goes into 6800 8 times with a remainder of 480.
Record the quotient 8 as the next digit in the result. 
Result so far: 99186.9367088
Subtracting 6320 from 6800 leaves us with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

In conclusion, the division gives 99186.9367088 with a balance of 4.8e-06.
