15262073 ÷ 866 
We want to divide 15262073 by 866.

Going ahead to step 1:
866 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 866

Step 2:
866 goes into 15 0 times with a remainder of 15.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Grab the next digit (2) from the dividend, add it to 15, then carry on: 152 / 866

Going ahead to step 3:
The number 866 fits into 152 0 times, leaving a remainder of 152.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 152 and we're left with 152.
Grab the next digit (6) from the dividend, add it to 152, then carry on: 1526 / 866

Advancing to step 4:
866 goes into 1526 1 times with a remainder of 660.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 866 away from 1526, we end up with 660.
Fetch the next digit (2) from the dividend, attach it to 660 and continue: 6602 / 866

Step 5:
If we divide 6602 by 866, we get 7 and a remainder of 540.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
Subtract 6062 from 6602 to get 540.
Fetch the next digit (0) from the dividend, attach it to 540 and continue: 5400 / 866

Step 6:
866 can be fit into 5400 6 times, resulting in a remainder of 204.
The number 6 becomes the next digit in our result. 
Result so far: 176.0
Subtract 5196 from 5400 to get 204.
Take the next digit (7) from the dividend and append it to 204, then repeat: 2047 / 866

Let's proceed to step 7:
If we divide 2047 by 866, we get 2 and a remainder of 315.
Put 2 as the next digit of the answer. 
Result so far: 1762.0
Deduct 1732 from 2047 and we're left with 315.
Append the next digit (3) from the dividend to 315 and continue with: 3153 / 866

Let's proceed to step 8:
866 can be fit into 3153 3 times, resulting in a remainder of 555.
The number 3 becomes the next digit in our result. 
Result so far: 17623.0
Subtracting 2598 from 3153 leaves us with 555.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5550, and continue the process.

Moving on to step 9:
When dividing 5550 by 866, we get 6 with a remainder of 354.
Write down 6 as next digit of the result. 
Result so far: 17623.6
Subtract 5196 from 5550 to get 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

Moving on to step 10:
866 goes into 3540 4 times with a remainder of 76.
Use 4 as the next digit of our solution. 
Result so far: 17623.64
Deduct 3464 from 3540 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 11:
760 divided by 866 is 0 with a remainder of 760.
The number 0 becomes the next digit in our result. 
Result so far: 17623.64
The remainder is 760 after subtracting 0 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

Going ahead to step 12:
The number 866 fits into 7600 8 times, leaving a remainder of 672.
Put 8 as the next digit of the answer. 
Result so far: 17623.6408
Subtract 6928 from 7600 to get 672.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6720, and continue the process.

Advancing to step 13:
When dividing 6720 by 866, we get 7 with a remainder of 658.
The next digit of our result is 7. 
Result so far: 17623.64087
If we take 6062 away from 6720, we end up with 658.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6580, and continue the process.

Step 14:
If we divide 6580 by 866, we get 7 and a remainder of 518.
Write down 7 as next digit of the result. 
Result so far: 17623.640877
Subtract 6062 from 6580 to get 518.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5180, and continue the process.

The final outcome is 17623.640877, with a leftover of 5.18e-05.
