We divide 90668845 by 6
We want to figure out the number of times 90668845 can be divided by 6.

Advancing to step 1:
6 can be fit into 9 1 times, resulting in a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 6 from 9 to get 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 6

Step 2:
6 can be fit into 30 5 times, resulting in a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Subtracting 30 from 30 leaves us with 0.
Fetch the next digit (6) from the dividend, attach it to 0 and continue: 6 / 6

Moving on to step 3:
If we divide 6 by 6, we get 1 and a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 151.0
The remainder is 0 after subtracting 6 from 6.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 6

Moving on to step 4:
When dividing 6 by 6, we get 1 with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1511.0
Subtract 6 from 6 to get 0.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 6

On to step 5:
When dividing 8 by 6, we get 1 with a remainder of 2.
The next digit of our result is 1. 
Result so far: 15111.0
If we subtract 6 from 8, we get 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 6

On to step 6:
6 can be fit into 28 4 times, resulting in a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 151114.0
Subtracting 24 from 28 leaves us with 4.
Grab the next digit (4) from the dividend, add it to 4, then carry on: 44 / 6

Moving on to step 7:
The number 6 fits into 44 7 times, leaving a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 1511147.0
Deduct 42 from 44 and we're left with 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 6

Going ahead to step 8:
When dividing 25 by 6, we get 4 with a remainder of 1.
Use 4 as the next digit of our solution. 
Result so far: 15111474.0
If we take 24 away from 25, 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.

Going ahead to step 9:
The number 6 fits into 10 1 times, leaving a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 15111474.1
If we subtract 6 from 10, we 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.

On to step 10:
If we divide 40 by 6, we get 6 and a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 15111474.16
If we subtract 36 from 40, we 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.

Let's proceed to step 11:
The number 6 fits into 40 6 times, leaving a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 15111474.166
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.

Our division results in 15111474.166 with a remaining 0.0004.
