Let's divide 70159874 by 310
We want to divide 70159874 by 310.

On to step 1:
When dividing 7 by 310, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 310

Step 2:
If we divide 70 by 310, we get 0 and a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 70, we get 70.
Bring next digit (1) of the dividend behind the 70 and repeat the process: 701 / 310

Step 3:
701 divided by 310 is 2 with a remainder of 81.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 620 from 701 and we're left with 81.
Append the next digit (5) from the dividend to 81 and continue with: 815 / 310

Going ahead to step 4:
310 can be fit into 815 2 times, resulting in a remainder of 195.
The next digit of our result is 2. 
Result so far: 22.0
Subtract 620 from 815 to get 195.
Include the next digit (9) from the dividend after 195, then repeat: 1959 / 310

Let's proceed to step 5:
310 goes into 1959 6 times with a remainder of 99.
Record the quotient 6 as the next digit in the result. 
Result so far: 226.0
If we subtract 1860 from 1959, we get 99.
Bring next digit (8) of the dividend behind the 99 and repeat the process: 998 / 310

Step 6:
310 can be fit into 998 3 times, resulting in a remainder of 68.
Write down 3 as next digit of the result. 
Result so far: 2263.0
Deduct 930 from 998 and we're left with 68.
Fetch the next digit (7) from the dividend, attach it to 68 and continue: 687 / 310

Let's proceed to step 7:
310 can be fit into 687 2 times, resulting in a remainder of 67.
The number 2 becomes the next digit in our result. 
Result so far: 22632.0
The remainder is 67 after subtracting 620 from 687.
Grab the next digit (4) from the dividend, add it to 67, then carry on: 674 / 310

Advancing to step 8:
310 can be fit into 674 2 times, resulting in a remainder of 54.
The next digit of our result is 2. 
Result so far: 226322.0
If we subtract 620 from 674, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 9:
The number 310 fits into 540 1 times, leaving a remainder of 230.
Record the quotient 1 as the next digit in the result. 
Result so far: 226322.1
If we take 310 away from 540, we end up with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Moving on to step 10:
If we divide 2300 by 310, we get 7 and a remainder of 130.
Record the quotient 7 as the next digit in the result. 
Result so far: 226322.17
If we take 2170 away from 2300, we end up with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Let's proceed to step 11:
310 goes into 1300 4 times with a remainder of 60.
Write down 4 as next digit of the result. 
Result so far: 226322.174
Deduct 1240 from 1300 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 12:
310 goes into 600 1 times with a remainder of 290.
The number 1 becomes the next digit in our result. 
Result so far: 226322.1741
Subtracting 310 from 600 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 13:
310 goes into 2900 9 times with a remainder of 110.
Use 9 as the next digit of our solution. 
Result so far: 226322.17419
Subtracting 2790 from 2900 leaves us with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Going ahead to step 14:
If we divide 1100 by 310, we get 3 and a remainder of 170.
Put 3 as the next digit of the answer. 
Result so far: 226322.174193
Deduct 930 from 1100 and we're left with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Going ahead to step 15:
When dividing 1700 by 310, we get 5 with a remainder of 150.
The next digit of our result is 5. 
Result so far: 226322.1741935
The remainder is 150 after subtracting 1550 from 1700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Going ahead to step 16:
When dividing 1500 by 310, we get 4 with a remainder of 260.
Put 4 as the next digit of the answer. 
Result so far: 226322.17419354
Subtract 1240 from 1500 to get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

The quotient of the division is 226322.17419354, and the remainder is 2.6e-07.
