We look at the division of 79589986 by 806 
Our goal is to divide 79589986 by 806.

On to step 1:
806 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (9) from the dividend and append it to 7, then repeat: 79 / 806

Let's proceed to step 2:
If we divide 79 by 806, we get 0 and a remainder of 79.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 79, we end up with 79.
Grab the next digit (5) from the dividend, add it to 79, then carry on: 795 / 806

Let's proceed to step 3:
When dividing 795 by 806, we get 0 with a remainder of 795.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 795 to get 795.
Bring next digit (8) of the dividend behind the 795 and repeat the process: 7958 / 806

Advancing to step 4:
7958 divided by 806 is 9 with a remainder of 704.
The next digit of our result is 9. 
Result so far: 9.0
Deduct 7254 from 7958 and we're left with 704.
Take the next digit (9) from the dividend and append it to 704, then repeat: 7049 / 806

Step 5:
When dividing 7049 by 806, we get 8 with a remainder of 601.
Write down 8 as next digit of the result. 
Result so far: 98.0
If we take 6448 away from 7049, we end up with 601.
Grab the next digit (9) from the dividend, add it to 601, then carry on: 6019 / 806

Advancing to step 6:
If we divide 6019 by 806, we get 7 and a remainder of 377.
Write down 7 as next digit of the result. 
Result so far: 987.0
If we take 5642 away from 6019, we end up with 377.
Take the next digit (8) from the dividend and append it to 377, then repeat: 3778 / 806

Moving on to step 7:
The number 806 fits into 3778 4 times, leaving a remainder of 554.
Record the quotient 4 as the next digit in the result. 
Result so far: 9874.0
Subtract 3224 from 3778 to get 554.
Take the next digit (6) from the dividend and append it to 554, then repeat: 5546 / 806

Going ahead to step 8:
When dividing 5546 by 806, we get 6 with a remainder of 710.
Write down 6 as next digit of the result. 
Result so far: 98746.0
The remainder is 710 after subtracting 4836 from 5546.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7100, and continue the process.

Let's proceed to step 9:
The number 806 fits into 7100 8 times, leaving a remainder of 652.
The number 8 becomes the next digit in our result. 
Result so far: 98746.8
If we take 6448 away from 7100, we end up with 652.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6520, and continue the process.

Going ahead to step 10:
806 can be fit into 6520 8 times, resulting in a remainder of 72.
Record the quotient 8 as the next digit in the result. 
Result so far: 98746.88
If we subtract 6448 from 6520, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

After the division, we end up with 98746.88 and a remainder of 0.072.
