99717259 ÷ 6 
We're looking to find how many times 6 goes into 99717259.

Step 1:
If we divide 9 by 6, we get 1 and a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 6 from 9, we get 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 6

Step 2:
6 goes into 39 6 times with a remainder of 3.
Use 6 as the next digit of our solution. 
Result so far: 16.0
Deduct 36 from 39 and we're left with 3.
Grab the next digit (7) from the dividend, add it to 3, then carry on: 37 / 6

Let's proceed to step 3:
The number 6 fits into 37 6 times, leaving a remainder of 1.
Write down 6 as next digit of the result. 
Result so far: 166.0
The remainder is 1 after subtracting 36 from 37.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 6

Going ahead to step 4:
6 goes into 11 1 times with a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 1661.0
If we take 6 away from 11, we end up with 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 6

Going ahead to step 5:
6 goes into 57 9 times with a remainder of 3.
The next digit of our result is 9. 
Result so far: 16619.0
Subtract 54 from 57 to get 3.
Take the next digit (2) from the dividend and append it to 3, then repeat: 32 / 6

Going ahead to step 6:
If we divide 32 by 6, we get 5 and a remainder of 2.
The next digit of our result is 5. 
Result so far: 166195.0
If we take 30 away from 32, we end up with 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 6

Moving on to step 7:
25 divided by 6 is 4 with a remainder of 1.
The next digit of our result is 4. 
Result so far: 1661954.0
Deduct 24 from 25 and we're left with 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 6

Step 8:
6 can be fit into 19 3 times, resulting in a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 16619543.0
If we take 18 away from 19, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 9:
6 can be fit into 10 1 times, resulting in a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 16619543.1
Subtract 6 from 10 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 10:
The number 6 fits into 40 6 times, leaving a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 16619543.16
If we take 36 away from 40, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 11:
The number 6 fits into 40 6 times, leaving a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 16619543.166
Deduct 36 from 40 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

After the division, we end up with 16619543.166 and a remainder of 0.0004.
