We look at the division of 17866066 by 847 
We're looking to find how many times 847 goes into 17866066.

Going ahead to step 1:
The number 847 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 847

Let's proceed to step 2:
847 can be fit into 17 0 times, resulting in a remainder of 17.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 17 and we're left with 17.
Fetch the next digit (8) from the dividend, attach it to 17 and continue: 178 / 847

Advancing to step 3:
When dividing 178 by 847, we get 0 with a remainder of 178.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 178 to get 178.
Bring next digit (6) of the dividend behind the 178 and repeat the process: 1786 / 847

Step 4:
1786 divided by 847 is 2 with a remainder of 92.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 1694 away from 1786, we end up with 92.
Append the next digit (6) from the dividend to 92 and continue with: 926 / 847

Step 5:
When dividing 926 by 847, we get 1 with a remainder of 79.
Put 1 as the next digit of the answer. 
Result so far: 21.0
The remainder is 79 after subtracting 847 from 926.
Append the next digit (0) from the dividend to 79 and continue with: 790 / 847

Moving on to step 6:
The number 847 fits into 790 0 times, leaving a remainder of 790.
The next digit of our result is 0. 
Result so far: 210.0
Subtracting 0 from 790 leaves us with 790.
Include the next digit (6) from the dividend after 790, then repeat: 7906 / 847

Going ahead to step 7:
If we divide 7906 by 847, we get 9 and a remainder of 283.
Record the quotient 9 as the next digit in the result. 
Result so far: 2109.0
Deduct 7623 from 7906 and we're left with 283.
Grab the next digit (6) from the dividend, add it to 283, then carry on: 2836 / 847

Let's proceed to step 8:
When dividing 2836 by 847, we get 3 with a remainder of 295.
Use 3 as the next digit of our solution. 
Result so far: 21093.0
Subtract 2541 from 2836 to get 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

Moving on to step 9:
The number 847 fits into 2950 3 times, leaving a remainder of 409.
Write down 3 as next digit of the result. 
Result so far: 21093.3
Subtracting 2541 from 2950 leaves us with 409.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4090, and continue the process.

Going ahead to step 10:
When dividing 4090 by 847, we get 4 with a remainder of 702.
Record the quotient 4 as the next digit in the result. 
Result so far: 21093.34
The remainder is 702 after subtracting 3388 from 4090.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7020, and continue the process.

Step 11:
847 goes into 7020 8 times with a remainder of 244.
The number 8 becomes the next digit in our result. 
Result so far: 21093.348
Deduct 6776 from 7020 and we're left with 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Step 12:
847 goes into 2440 2 times with a remainder of 746.
The number 2 becomes the next digit in our result. 
Result so far: 21093.3482
Deduct 1694 from 2440 and we're left with 746.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7460, and continue the process.

Advancing to step 13:
When dividing 7460 by 847, we get 8 with a remainder of 684.
Record the quotient 8 as the next digit in the result. 
Result so far: 21093.34828
If we subtract 6776 from 7460, we get 684.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6840, and continue the process.

Step 14:
If we divide 6840 by 847, we get 8 and a remainder of 64.
Use 8 as the next digit of our solution. 
Result so far: 21093.348288
If we take 6776 away from 6840, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The final outcome is 21093.348288, with a leftover of 6.4e-06.
