We're dividing 15466739 by 806 
We want to divide 15466739 by 806.

Step 1:
The number 806 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 806

Moving on to step 2:
The number 806 fits into 15 0 times, leaving a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Append the next digit (4) from the dividend to 15 and continue with: 154 / 806

Going ahead to step 3:
The number 806 fits into 154 0 times, leaving a remainder of 154.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 154 after subtracting 0 from 154.
Take the next digit (6) from the dividend and append it to 154, then repeat: 1546 / 806

On to step 4:
1546 divided by 806 is 1 with a remainder of 740.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 806 from 1546, we get 740.
Append the next digit (6) from the dividend to 740 and continue with: 7406 / 806

On to step 5:
7406 divided by 806 is 9 with a remainder of 152.
Put 9 as the next digit of the answer. 
Result so far: 19.0
If we subtract 7254 from 7406, we get 152.
Include the next digit (7) from the dividend after 152, then repeat: 1527 / 806

On to step 6:
If we divide 1527 by 806, we get 1 and a remainder of 721.
The number 1 becomes the next digit in our result. 
Result so far: 191.0
If we take 806 away from 1527, we end up with 721.
Take the next digit (3) from the dividend and append it to 721, then repeat: 7213 / 806

Let's proceed to step 7:
If we divide 7213 by 806, we get 8 and a remainder of 765.
Use 8 as the next digit of our solution. 
Result so far: 1918.0
Subtracting 6448 from 7213 leaves us with 765.
Append the next digit (9) from the dividend to 765 and continue with: 7659 / 806

Step 8:
When dividing 7659 by 806, we get 9 with a remainder of 405.
Record the quotient 9 as the next digit in the result. 
Result so far: 19189.0
Subtracting 7254 from 7659 leaves us with 405.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

Going ahead to step 9:
806 can be fit into 4050 5 times, resulting in a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 19189.5
If we take 4030 away from 4050, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 10:
806 goes into 200 0 times with a remainder of 200.
Write down 0 as next digit of the result. 
Result so far: 19189.5
If we take 0 away from 200, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

On to step 11:
806 goes into 2000 2 times with a remainder of 388.
Write down 2 as next digit of the result. 
Result so far: 19189.502
If we subtract 1612 from 2000, we get 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Advancing to step 12:
806 can be fit into 3880 4 times, resulting in a remainder of 656.
The next digit of our result is 4. 
Result so far: 19189.5024
Subtract 3224 from 3880 to get 656.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6560, and continue the process.

Let's proceed to step 13:
6560 divided by 806 is 8 with a remainder of 112.
The number 8 becomes the next digit in our result. 
Result so far: 19189.50248
If we subtract 6448 from 6560, we get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Advancing to step 14:
When dividing 1120 by 806, we get 1 with a remainder of 314.
Use 1 as the next digit of our solution. 
Result so far: 19189.502481
The remainder is 314 after subtracting 806 from 1120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Let's proceed to step 15:
806 goes into 3140 3 times with a remainder of 722.
Record the quotient 3 as the next digit in the result. 
Result so far: 19189.5024813
If we take 2418 away from 3140, we end up with 722.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7220, and continue the process.

On to step 16:
When dividing 7220 by 806, we get 8 with a remainder of 772.
Write down 8 as next digit of the result. 
Result so far: 19189.50248138
If we subtract 6448 from 7220, we get 772.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7720, and continue the process.

The final outcome is 19189.50248138, with a leftover of 7.72e-07.
