We look at the division of 78569908 by 310 
Let's see how many times 310 fits into 78569908.

Advancing to step 1:
The number 310 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 310

Moving on to step 2:
When dividing 78 by 310, we get 0 with a remainder of 78.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 78, we end up with 78.
Fetch the next digit (5) from the dividend, attach it to 78 and continue: 785 / 310

Step 3:
310 can be fit into 785 2 times, resulting in a remainder of 165.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 620 from 785, we get 165.
Take the next digit (6) from the dividend and append it to 165, then repeat: 1656 / 310

Moving on to step 4:
If we divide 1656 by 310, we get 5 and a remainder of 106.
Put 5 as the next digit of the answer. 
Result so far: 25.0
If we take 1550 away from 1656, we end up with 106.
Include the next digit (9) from the dividend after 106, then repeat: 1069 / 310

Going ahead to step 5:
1069 divided by 310 is 3 with a remainder of 139.
Use 3 as the next digit of our solution. 
Result so far: 253.0
If we subtract 930 from 1069, we get 139.
Grab the next digit (9) from the dividend, add it to 139, then carry on: 1399 / 310

Step 6:
When dividing 1399 by 310, we get 4 with a remainder of 159.
Use 4 as the next digit of our solution. 
Result so far: 2534.0
Subtract 1240 from 1399 to get 159.
Bring next digit (0) of the dividend behind the 159 and repeat the process: 1590 / 310

On to step 7:
The number 310 fits into 1590 5 times, leaving a remainder of 40.
Put 5 as the next digit of the answer. 
Result so far: 25345.0
Subtract 1550 from 1590 to get 40.
Fetch the next digit (8) from the dividend, attach it to 40 and continue: 408 / 310

Advancing to step 8:
When dividing 408 by 310, we get 1 with a remainder of 98.
Record the quotient 1 as the next digit in the result. 
Result so far: 253451.0
Deduct 310 from 408 and we're left with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Moving on to step 9:
310 can be fit into 980 3 times, resulting in a remainder of 50.
Put 3 as the next digit of the answer. 
Result so far: 253451.3
Subtracting 930 from 980 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 10:
The number 310 fits into 500 1 times, leaving a remainder of 190.
The number 1 becomes the next digit in our result. 
Result so far: 253451.31
If we subtract 310 from 500, we get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Moving on to step 11:
The number 310 fits into 1900 6 times, leaving a remainder of 40.
Write down 6 as next digit of the result. 
Result so far: 253451.316
The remainder is 40 after subtracting 1860 from 1900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 12:
If we divide 400 by 310, we get 1 and a remainder of 90.
The next digit of our result is 1. 
Result so far: 253451.3161
The remainder is 90 after subtracting 310 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Step 13:
310 can be fit into 900 2 times, resulting in a remainder of 280.
Write down 2 as next digit of the result. 
Result so far: 253451.31612
If we subtract 620 from 900, we get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Moving on to step 14:
When dividing 2800 by 310, we get 9 with a remainder of 10.
Write down 9 as next digit of the result. 
Result so far: 253451.316129
Subtract 2790 from 2800 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 15:
310 can be fit into 100 0 times, resulting in a remainder of 100.
Record the quotient 0 as the next digit in the result. 
Result so far: 253451.316129
Subtracting 0 from 100 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 16:
310 goes into 1000 3 times with a remainder of 70.
Put 3 as the next digit of the answer. 
Result so far: 253451.31612903
If we take 930 away from 1000, we end up 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.

The quotient of the division is 253451.31612903, and the remainder is 7e-08.
