Let's divide 70513531 by 279
We want to figure out the number of times 70513531 can be divided by 279.

Advancing to step 1:
When dividing 7 by 279, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 279

On to step 2:
The number 279 fits into 70 0 times, leaving a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 70, we end up with 70.
Grab the next digit (5) from the dividend, add it to 70, then carry on: 705 / 279

Let's proceed to step 3:
279 can be fit into 705 2 times, resulting in a remainder of 147.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 558 from 705 to get 147.
Grab the next digit (1) from the dividend, add it to 147, then carry on: 1471 / 279

Moving on to step 4:
If we divide 1471 by 279, we get 5 and a remainder of 76.
Use 5 as the next digit of our solution. 
Result so far: 25.0
The remainder is 76 after subtracting 1395 from 1471.
Append the next digit (3) from the dividend to 76 and continue with: 763 / 279

Going ahead to step 5:
The number 279 fits into 763 2 times, leaving a remainder of 205.
Put 2 as the next digit of the answer. 
Result so far: 252.0
Subtracting 558 from 763 leaves us with 205.
Bring next digit (5) of the dividend behind the 205 and repeat the process: 2055 / 279

Going ahead to step 6:
When dividing 2055 by 279, we get 7 with a remainder of 102.
The number 7 becomes the next digit in our result. 
Result so far: 2527.0
If we take 1953 away from 2055, we end up with 102.
Bring next digit (3) of the dividend behind the 102 and repeat the process: 1023 / 279

Step 7:
When dividing 1023 by 279, we get 3 with a remainder of 186.
Write down 3 as next digit of the result. 
Result so far: 25273.0
The remainder is 186 after subtracting 837 from 1023.
Take the next digit (1) from the dividend and append it to 186, then repeat: 1861 / 279

Moving on to step 8:
1861 divided by 279 is 6 with a remainder of 187.
Use 6 as the next digit of our solution. 
Result so far: 252736.0
Deduct 1674 from 1861 and we're left with 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

On to step 9:
When dividing 1870 by 279, we get 6 with a remainder of 196.
Use 6 as the next digit of our solution. 
Result so far: 252736.6
If we subtract 1674 from 1870, we get 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

On to step 10:
279 can be fit into 1960 7 times, resulting in a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 252736.67
Deduct 1953 from 1960 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 11:
If we divide 70 by 279, we get 0 and a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 252736.67
If we take 0 away from 70, 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.

Step 12:
When dividing 700 by 279, we get 2 with a remainder of 142.
The number 2 becomes the next digit in our result. 
Result so far: 252736.6702
Subtracting 558 from 700 leaves us with 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Step 13:
1420 divided by 279 is 5 with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 252736.67025
Deduct 1395 from 1420 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 14:
If we divide 250 by 279, we get 0 and a remainder of 250.
The number 0 becomes the next digit in our result. 
Result so far: 252736.67025
Subtract 0 from 250 to get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Let's proceed to step 15:
279 can be fit into 2500 8 times, resulting in a remainder of 268.
The next digit of our result is 8. 
Result so far: 252736.6702508
If we take 2232 away from 2500, we end up with 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

On to step 16:
279 goes into 2680 9 times with a remainder of 169.
The next digit of our result is 9. 
Result so far: 252736.67025089
If we subtract 2511 from 2680, we get 169.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1690, and continue the process.

After the division, we end up with 252736.67025089 and a remainder of 1.69e-07.
