We look at the division of 15179113 by 561 
We want to figure out the number of times 15179113 can be divided by 561.

Let's proceed to step 1:
When dividing 1 by 561, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 561

On to step 2:
If we divide 15 by 561, we get 0 and a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 15 after subtracting 0 from 15.
Append the next digit (1) from the dividend to 15 and continue with: 151 / 561

On to step 3:
When dividing 151 by 561, we get 0 with a remainder of 151.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 151, we end up with 151.
Append the next digit (7) from the dividend to 151 and continue with: 1517 / 561

Moving on to step 4:
The number 561 fits into 1517 2 times, leaving a remainder of 395.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 1122 from 1517 and we're left with 395.
Grab the next digit (9) from the dividend, add it to 395, then carry on: 3959 / 561

Let's proceed to step 5:
561 goes into 3959 7 times with a remainder of 32.
The number 7 becomes the next digit in our result. 
Result so far: 27.0
The remainder is 32 after subtracting 3927 from 3959.
Take the next digit (1) from the dividend and append it to 32, then repeat: 321 / 561

On to step 6:
561 goes into 321 0 times with a remainder of 321.
Use 0 as the next digit of our solution. 
Result so far: 270.0
Deduct 0 from 321 and we're left with 321.
Include the next digit (1) from the dividend after 321, then repeat: 3211 / 561

Going ahead to step 7:
3211 divided by 561 is 5 with a remainder of 406.
The next digit of our result is 5. 
Result so far: 2705.0
Subtract 2805 from 3211 to get 406.
Fetch the next digit (3) from the dividend, attach it to 406 and continue: 4063 / 561

Moving on to step 8:
The number 561 fits into 4063 7 times, leaving a remainder of 136.
The number 7 becomes the next digit in our result. 
Result so far: 27057.0
If we take 3927 away from 4063, we end up with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Step 9:
When dividing 1360 by 561, we get 2 with a remainder of 238.
The number 2 becomes the next digit in our result. 
Result so far: 27057.2
If we subtract 1122 from 1360, we get 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Step 10:
When dividing 2380 by 561, we get 4 with a remainder of 136.
Use 4 as the next digit of our solution. 
Result so far: 27057.24
If we subtract 2244 from 2380, we get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

On to step 11:
561 can be fit into 1360 2 times, resulting in a remainder of 238.
Use 2 as the next digit of our solution. 
Result so far: 27057.242
Subtract 1122 from 1360 to get 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Moving on to step 12:
2380 divided by 561 is 4 with a remainder of 136.
Use 4 as the next digit of our solution. 
Result so far: 27057.2424
If we subtract 2244 from 2380, we get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Step 13:
If we divide 1360 by 561, we get 2 and a remainder of 238.
Write down 2 as next digit of the result. 
Result so far: 27057.24242
Subtract 1122 from 1360 to get 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Moving on to step 14:
If we divide 2380 by 561, we get 4 and a remainder of 136.
Record the quotient 4 as the next digit in the result. 
Result so far: 27057.242424
Subtracting 2244 from 2380 leaves us with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Moving on to step 15:
561 goes into 1360 2 times with a remainder of 238.
Put 2 as the next digit of the answer. 
Result so far: 27057.2424242
Subtracting 1122 from 1360 leaves us with 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Step 16:
When dividing 2380 by 561, we get 4 with a remainder of 136.
The number 4 becomes the next digit in our result. 
Result so far: 27057.24242424
If we subtract 2244 from 2380, we get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

After the division, we end up with 27057.24242424 and a remainder of 1.36e-07.
