We look at the division of 79070909 by 561 
We want to divide 79070909 by 561.

Going ahead to step 1:
7 divided by 561 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 561

On to step 2:
561 goes into 79 0 times with a remainder of 79.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 79, we end up with 79.
Grab the next digit (0) from the dividend, add it to 79, then carry on: 790 / 561

On to step 3:
790 divided by 561 is 1 with a remainder of 229.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 561 from 790 and we're left with 229.
Grab the next digit (7) from the dividend, add it to 229, then carry on: 2297 / 561

On to step 4:
If we divide 2297 by 561, we get 4 and a remainder of 53.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
If we subtract 2244 from 2297, we get 53.
Bring next digit (0) of the dividend behind the 53 and repeat the process: 530 / 561

Let's proceed to step 5:
The number 561 fits into 530 0 times, leaving a remainder of 530.
Write down 0 as next digit of the result. 
Result so far: 140.0
The remainder is 530 after subtracting 0 from 530.
Grab the next digit (9) from the dividend, add it to 530, then carry on: 5309 / 561

Going ahead to step 6:
561 goes into 5309 9 times with a remainder of 260.
Write down 9 as next digit of the result. 
Result so far: 1409.0
If we subtract 5049 from 5309, we get 260.
Take the next digit (0) from the dividend and append it to 260, then repeat: 2600 / 561

On to step 7:
2600 divided by 561 is 4 with a remainder of 356.
Use 4 as the next digit of our solution. 
Result so far: 14094.0
The remainder is 356 after subtracting 2244 from 2600.
Include the next digit (9) from the dividend after 356, then repeat: 3569 / 561

Let's proceed to step 8:
If we divide 3569 by 561, we get 6 and a remainder of 203.
The next digit of our result is 6. 
Result so far: 140946.0
If we subtract 3366 from 3569, we get 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

Going ahead to step 9:
2030 divided by 561 is 3 with a remainder of 347.
The number 3 becomes the next digit in our result. 
Result so far: 140946.3
The remainder is 347 after subtracting 1683 from 2030.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3470, and continue the process.

Advancing to step 10:
If we divide 3470 by 561, we get 6 and a remainder of 104.
Record the quotient 6 as the next digit in the result. 
Result so far: 140946.36
The remainder is 104 after subtracting 3366 from 3470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Step 11:
561 goes into 1040 1 times with a remainder of 479.
Use 1 as the next digit of our solution. 
Result so far: 140946.361
Subtract 561 from 1040 to get 479.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4790, and continue the process.

Going ahead to step 12:
4790 divided by 561 is 8 with a remainder of 302.
Use 8 as the next digit of our solution. 
Result so far: 140946.3618
Subtracting 4488 from 4790 leaves us with 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

On to step 13:
3020 divided by 561 is 5 with a remainder of 215.
Record the quotient 5 as the next digit in the result. 
Result so far: 140946.36185
Subtract 2805 from 3020 to get 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Let's proceed to step 14:
If we divide 2150 by 561, we get 3 and a remainder of 467.
Use 3 as the next digit of our solution. 
Result so far: 140946.361853
The remainder is 467 after subtracting 1683 from 2150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4670, and continue the process.

On to step 15:
561 can be fit into 4670 8 times, resulting in a remainder of 182.
Write down 8 as next digit of the result. 
Result so far: 140946.3618538
Subtracting 4488 from 4670 leaves us with 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Step 16:
If we divide 1820 by 561, we get 3 and a remainder of 137.
Use 3 as the next digit of our solution. 
Result so far: 140946.36185383
Subtracting 1683 from 1820 leaves us with 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

The quotient of the division is 140946.36185383, and the remainder is 1.37e-07.
