We divide 15310305 by 856
Our goal is to divide 15310305 by 856.

On to step 1:
The number 856 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 856

Going ahead to step 2:
15 divided by 856 is 0 with a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 15 after subtracting 0 from 15.
Fetch the next digit (3) from the dividend, attach it to 15 and continue: 153 / 856

Moving on to step 3:
The number 856 fits into 153 0 times, leaving a remainder of 153.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 153 to get 153.
Append the next digit (1) from the dividend to 153 and continue with: 1531 / 856

Let's proceed to step 4:
856 can be fit into 1531 1 times, resulting in a remainder of 675.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 675 after subtracting 856 from 1531.
Take the next digit (0) from the dividend and append it to 675, then repeat: 6750 / 856

Moving on to step 5:
856 goes into 6750 7 times with a remainder of 758.
Write down 7 as next digit of the result. 
Result so far: 17.0
The remainder is 758 after subtracting 5992 from 6750.
Take the next digit (3) from the dividend and append it to 758, then repeat: 7583 / 856

Step 6:
The number 856 fits into 7583 8 times, leaving a remainder of 735.
Put 8 as the next digit of the answer. 
Result so far: 178.0
The remainder is 735 after subtracting 6848 from 7583.
Fetch the next digit (0) from the dividend, attach it to 735 and continue: 7350 / 856

Going ahead to step 7:
856 goes into 7350 8 times with a remainder of 502.
Record the quotient 8 as the next digit in the result. 
Result so far: 1788.0
The remainder is 502 after subtracting 6848 from 7350.
Take the next digit (5) from the dividend and append it to 502, then repeat: 5025 / 856

On to step 8:
If we divide 5025 by 856, we get 5 and a remainder of 745.
The next digit of our result is 5. 
Result so far: 17885.0
Subtracting 4280 from 5025 leaves us with 745.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7450, and continue the process.

Let's proceed to step 9:
The number 856 fits into 7450 8 times, leaving a remainder of 602.
Record the quotient 8 as the next digit in the result. 
Result so far: 17885.8
If we take 6848 away from 7450, we end up with 602.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6020, and continue the process.

Advancing to step 10:
856 goes into 6020 7 times with a remainder of 28.
Use 7 as the next digit of our solution. 
Result so far: 17885.87
If we take 5992 away from 6020, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 11:
280 divided by 856 is 0 with a remainder of 280.
Record the quotient 0 as the next digit in the result. 
Result so far: 17885.87
Subtracting 0 from 280 leaves us with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Let's proceed to step 12:
The number 856 fits into 2800 3 times, leaving a remainder of 232.
Use 3 as the next digit of our solution. 
Result so far: 17885.8703
If we subtract 2568 from 2800, we get 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

On to step 13:
856 can be fit into 2320 2 times, resulting in a remainder of 608.
Put 2 as the next digit of the answer. 
Result so far: 17885.87032
Subtract 1712 from 2320 to get 608.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

Step 14:
When dividing 6080 by 856, we get 7 with a remainder of 88.
Record the quotient 7 as the next digit in the result. 
Result so far: 17885.870327
Deduct 5992 from 6080 and we're left with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Advancing to step 15:
856 goes into 880 1 times with a remainder of 24.
The number 1 becomes the next digit in our result. 
Result so far: 17885.8703271
If we take 856 away from 880, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 16:
The number 856 fits into 240 0 times, leaving a remainder of 240.
Record the quotient 0 as the next digit in the result. 
Result so far: 17885.8703271
Subtract 0 from 240 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

The final outcome is 17885.8703271, with a leftover of 2.4e-07.
