Let's divide 15909752 by 806
We're looking to find how many times 806 goes into 15909752.

On to step 1:
If we divide 1 by 806, we get 0 and 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.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 806

Moving on to step 2:
806 can be fit into 15 0 times, resulting in a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Fetch the next digit (9) from the dividend, attach it to 15 and continue: 159 / 806

Step 3:
806 can be fit into 159 0 times, resulting in a remainder of 159.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 159 leaves us with 159.
Append the next digit (0) from the dividend to 159 and continue with: 1590 / 806

Going ahead to step 4:
806 goes into 1590 1 times with a remainder of 784.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 806 from 1590 and we're left with 784.
Fetch the next digit (9) from the dividend, attach it to 784 and continue: 7849 / 806

Let's proceed to step 5:
806 goes into 7849 9 times with a remainder of 595.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
Subtract 7254 from 7849 to get 595.
Bring next digit (7) of the dividend behind the 595 and repeat the process: 5957 / 806

Going ahead to step 6:
The number 806 fits into 5957 7 times, leaving a remainder of 315.
Put 7 as the next digit of the answer. 
Result so far: 197.0
If we subtract 5642 from 5957, we get 315.
Grab the next digit (5) from the dividend, add it to 315, then carry on: 3155 / 806

Advancing to step 7:
806 goes into 3155 3 times with a remainder of 737.
The number 3 becomes the next digit in our result. 
Result so far: 1973.0
Deduct 2418 from 3155 and we're left with 737.
Include the next digit (2) from the dividend after 737, then repeat: 7372 / 806

Advancing to step 8:
If we divide 7372 by 806, we get 9 and a remainder of 118.
Write down 9 as next digit of the result. 
Result so far: 19739.0
If we subtract 7254 from 7372, we get 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Advancing to step 9:
When dividing 1180 by 806, we get 1 with a remainder of 374.
Use 1 as the next digit of our solution. 
Result so far: 19739.1
Subtracting 806 from 1180 leaves us with 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

On to step 10:
When dividing 3740 by 806, we get 4 with a remainder of 516.
Record the quotient 4 as the next digit in the result. 
Result so far: 19739.14
The remainder is 516 after subtracting 3224 from 3740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

Let's proceed to step 11:
When dividing 5160 by 806, we get 6 with a remainder of 324.
Record the quotient 6 as the next digit in the result. 
Result so far: 19739.146
If we subtract 4836 from 5160, we get 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Moving on to step 12:
The number 806 fits into 3240 4 times, leaving a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 19739.1464
Deduct 3224 from 3240 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 13:
When dividing 160 by 806, we get 0 with a remainder of 160.
The number 0 becomes the next digit in our result. 
Result so far: 19739.1464
Deduct 0 from 160 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 14:
1600 divided by 806 is 1 with a remainder of 794.
Use 1 as the next digit of our solution. 
Result so far: 19739.146401
If we take 806 away from 1600, we end up with 794.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7940, and continue the process.

Going ahead to step 15:
The number 806 fits into 7940 9 times, leaving a remainder of 686.
The next digit of our result is 9. 
Result so far: 19739.1464019
The remainder is 686 after subtracting 7254 from 7940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6860, and continue the process.

Advancing to step 16:
806 can be fit into 6860 8 times, resulting in a remainder of 412.
Record the quotient 8 as the next digit in the result. 
Result so far: 19739.14640198
Subtract 6448 from 6860 to get 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

After the division, we end up with 19739.14640198 and a remainder of 4.12e-07.
