We're dividing 17090787 by 945 
Let's see how many times 945 fits into 17090787.

Going ahead to step 1:
The number 945 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 945

Moving on to step 2:
945 goes into 17 0 times with a remainder of 17.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 17 and we're left with 17.
Include the next digit (0) from the dividend after 17, then repeat: 170 / 945

Advancing to step 3:
When dividing 170 by 945, we get 0 with a remainder of 170.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 170 and we're left with 170.
Bring next digit (9) of the dividend behind the 170 and repeat the process: 1709 / 945

On to step 4:
945 goes into 1709 1 times with a remainder of 764.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 945 from 1709 leaves us with 764.
Bring next digit (0) of the dividend behind the 764 and repeat the process: 7640 / 945

Step 5:
7640 divided by 945 is 8 with a remainder of 80.
Write down 8 as next digit of the result. 
Result so far: 18.0
Subtract 7560 from 7640 to get 80.
Include the next digit (7) from the dividend after 80, then repeat: 807 / 945

Going ahead to step 6:
945 goes into 807 0 times with a remainder of 807.
Put 0 as the next digit of the answer. 
Result so far: 180.0
Deduct 0 from 807 and we're left with 807.
Fetch the next digit (8) from the dividend, attach it to 807 and continue: 8078 / 945

Moving on to step 7:
When dividing 8078 by 945, we get 8 with a remainder of 518.
The next digit of our result is 8. 
Result so far: 1808.0
Deduct 7560 from 8078 and we're left with 518.
Take the next digit (7) from the dividend and append it to 518, then repeat: 5187 / 945

Let's proceed to step 8:
5187 divided by 945 is 5 with a remainder of 462.
The next digit of our result is 5. 
Result so far: 18085.0
Deduct 4725 from 5187 and we're left with 462.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4620, and continue the process.

Step 9:
If we divide 4620 by 945, we get 4 and a remainder of 840.
The next digit of our result is 4. 
Result so far: 18085.4
If we subtract 3780 from 4620, we get 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8400, and continue the process.

On to step 10:
8400 divided by 945 is 8 with a remainder of 840.
Put 8 as the next digit of the answer. 
Result so far: 18085.48
If we take 7560 away from 8400, we end up with 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8400, and continue the process.

Step 11:
945 goes into 8400 8 times with a remainder of 840.
The next digit of our result is 8. 
Result so far: 18085.488
The remainder is 840 after subtracting 7560 from 8400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8400, and continue the process.

The final outcome is 18085.488, with a leftover of 0.084.
