78353060 ÷ 771 
We want to figure out the number of times 78353060 can be divided by 771.

On to step 1:
When dividing 7 by 771, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 771

On to step 2:
78 divided by 771 is 0 with a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Grab the next digit (3) from the dividend, add it to 78, then carry on: 783 / 771

Moving on to step 3:
771 goes into 783 1 times with a remainder of 12.
The next digit of our result is 1. 
Result so far: 1.0
If we take 771 away from 783, we end up with 12.
Include the next digit (5) from the dividend after 12, then repeat: 125 / 771

Step 4:
When dividing 125 by 771, we get 0 with a remainder of 125.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Deduct 0 from 125 and we're left with 125.
Grab the next digit (3) from the dividend, add it to 125, then carry on: 1253 / 771

Advancing to step 5:
1253 divided by 771 is 1 with a remainder of 482.
Record the quotient 1 as the next digit in the result. 
Result so far: 101.0
If we take 771 away from 1253, we end up with 482.
Take the next digit (0) from the dividend and append it to 482, then repeat: 4820 / 771

Advancing to step 6:
If we divide 4820 by 771, we get 6 and a remainder of 194.
Put 6 as the next digit of the answer. 
Result so far: 1016.0
If we subtract 4626 from 4820, we get 194.
Grab the next digit (6) from the dividend, add it to 194, then carry on: 1946 / 771

Moving on to step 7:
The number 771 fits into 1946 2 times, leaving a remainder of 404.
The next digit of our result is 2. 
Result so far: 10162.0
Deduct 1542 from 1946 and we're left with 404.
Append the next digit (0) from the dividend to 404 and continue with: 4040 / 771

Going ahead to step 8:
4040 divided by 771 is 5 with a remainder of 185.
The number 5 becomes the next digit in our result. 
Result so far: 101625.0
If we take 3855 away from 4040, we end up with 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Advancing to step 9:
771 can be fit into 1850 2 times, resulting in a remainder of 308.
Write down 2 as next digit of the result. 
Result so far: 101625.2
If we take 1542 away from 1850, we end up with 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Going ahead to step 10:
771 goes into 3080 3 times with a remainder of 767.
The next digit of our result is 3. 
Result so far: 101625.23
The remainder is 767 after subtracting 2313 from 3080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7670, and continue the process.

Step 11:
When dividing 7670 by 771, we get 9 with a remainder of 731.
The number 9 becomes the next digit in our result. 
Result so far: 101625.239
If we subtract 6939 from 7670, we get 731.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7310, and continue the process.

Step 12:
7310 divided by 771 is 9 with a remainder of 371.
Put 9 as the next digit of the answer. 
Result so far: 101625.2399
If we subtract 6939 from 7310, we get 371.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3710, and continue the process.

In conclusion, the division gives 101625.2399 with a balance of 0.00371.
