We divide 12687357 by 806
We want to divide 12687357 by 806.

Advancing to step 1:
806 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 806

Step 2:
If we divide 12 by 806, we get 0 and a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Grab the next digit (6) from the dividend, add it to 12, then carry on: 126 / 806

Moving on to step 3:
If we divide 126 by 806, we get 0 and a remainder of 126.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 126 to get 126.
Take the next digit (8) from the dividend and append it to 126, then repeat: 1268 / 806

Advancing to step 4:
1268 divided by 806 is 1 with a remainder of 462.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 462 after subtracting 806 from 1268.
Fetch the next digit (7) from the dividend, attach it to 462 and continue: 4627 / 806

Let's proceed to step 5:
If we divide 4627 by 806, we get 5 and a remainder of 597.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
If we subtract 4030 from 4627, we get 597.
Grab the next digit (3) from the dividend, add it to 597, then carry on: 5973 / 806

Step 6:
When dividing 5973 by 806, we get 7 with a remainder of 331.
Use 7 as the next digit of our solution. 
Result so far: 157.0
If we subtract 5642 from 5973, we get 331.
Append the next digit (5) from the dividend to 331 and continue with: 3315 / 806

Moving on to step 7:
3315 divided by 806 is 4 with a remainder of 91.
Record the quotient 4 as the next digit in the result. 
Result so far: 1574.0
The remainder is 91 after subtracting 3224 from 3315.
Grab the next digit (7) from the dividend, add it to 91, then carry on: 917 / 806

On to step 8:
If we divide 917 by 806, we get 1 and a remainder of 111.
Use 1 as the next digit of our solution. 
Result so far: 15741.0
If we take 806 away from 917, we end up with 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Step 9:
1110 divided by 806 is 1 with a remainder of 304.
Use 1 as the next digit of our solution. 
Result so far: 15741.1
Subtracting 806 from 1110 leaves us with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Advancing to step 10:
The number 806 fits into 3040 3 times, leaving a remainder of 622.
Write down 3 as next digit of the result. 
Result so far: 15741.13
Subtracting 2418 from 3040 leaves us with 622.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6220, and continue the process.

Moving on to step 11:
806 goes into 6220 7 times with a remainder of 578.
The number 7 becomes the next digit in our result. 
Result so far: 15741.137
Subtract 5642 from 6220 to get 578.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5780, and continue the process.

Advancing to step 12:
When dividing 5780 by 806, we get 7 with a remainder of 138.
Write down 7 as next digit of the result. 
Result so far: 15741.1377
Subtracting 5642 from 5780 leaves us with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

The final result is 15741.1377 with a remainder of 0.00138.
