The number 866 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 866

On to step 2:
866 goes into 45 0 times with a remainder of 45.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 45 and we're left with 45.
Append the next digit (7) from the dividend to 45 and continue with: 457 / 866

Going ahead to step 3:
457 divided by 866 is 0 with a remainder of 457.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 457 and we're left with 457.
Grab the next digit (9) from the dividend, add it to 457, then carry on: 4579 / 866

Moving on to step 4:
4579 divided by 866 is 5 with a remainder of 249.
Write down 5 as next digit of the result. 
Result so far: 5.0
Deduct 4330 from 4579 and we're left with 249.
Take the next digit (9) from the dividend and append it to 249, then repeat: 2499 / 866

Let's proceed to step 5:
The number 866 fits into 2499 2 times, leaving a remainder of 767.
Put 2 as the next digit of the answer. 
Result so far: 52.0
If we subtract 1732 from 2499, we get 767.
Take the next digit (4) from the dividend and append it to 767, then repeat: 7674 / 866

Let's proceed to step 6:
The number 866 fits into 7674 8 times, leaving a remainder of 746.
The next digit of our result is 8. 
Result so far: 528.0
Deduct 6928 from 7674 and we're left with 746.
Fetch the next digit (1) from the dividend, attach it to 746 and continue: 7461 / 866

Let's proceed to step 7:
The number 866 fits into 7461 8 times, leaving a remainder of 533.
Put 8 as the next digit of the answer. 
Result so far: 5288.0
Subtract 6928 from 7461 to get 533.
Fetch the next digit (2) from the dividend, attach it to 533 and continue: 5332 / 866

Going ahead to step 8:
866 can be fit into 5332 6 times, resulting in a remainder of 136.
The number 6 becomes the next digit in our result. 
Result so far: 52886.0
Deduct 5196 from 5332 and we're left 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.

Let's proceed to step 9:
1360 divided by 866 is 1 with a remainder of 494.
Write down 1 as next digit of the result. 
Result so far: 52886.1
Deduct 866 from 1360 and we're left with 494.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4940, and continue the process.

Step 10:
If we divide 4940 by 866, we get 5 and a remainder of 610.
Put 5 as the next digit of the answer. 
Result so far: 52886.15
If we subtract 4330 from 4940, we get 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

On to step 11:
6100 divided by 866 is 7 with a remainder of 38.
Record the quotient 7 as the next digit in the result. 
Result so far: 52886.157
If we take 6062 away from 6100, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 12:
380 divided by 866 is 0 with a remainder of 380.
The next digit of our result is 0. 
Result so far: 52886.157
If we take 0 away from 380, we end up with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Let's proceed to step 13:
3800 divided by 866 is 4 with a remainder of 336.
Record the quotient 4 as the next digit in the result. 
Result so far: 52886.15704
If we subtract 3464 from 3800, we get 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Moving on to step 14:
866 goes into 3360 3 times with a remainder of 762.
Put 3 as the next digit of the answer. 
Result so far: 52886.157043
If we subtract 2598 from 3360, we get 762.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7620, and continue the process.

Let's proceed to step 15:
The number 866 fits into 7620 8 times, leaving a remainder of 692.
Put 8 as the next digit of the answer. 
Result so far: 52886.1570438
Deduct 6928 from 7620 and we're left with 692.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6920, and continue the process.

Advancing to step 16:
The number 866 fits into 6920 7 times, leaving a remainder of 858.
The number 7 becomes the next digit in our result. 
Result so far: 52886.15704387
Subtracting 6062 from 6920 leaves us with 858.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8580, and continue the process.

The final outcome is 52886.15704387, with a leftover of 8.58e-07.
