90948171 ÷ 10 
We're looking to find how many times 10 goes into 90948171.

Step 1:
When dividing 9 by 10, we get 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 10

Let's proceed to step 2:
10 goes into 90 9 times with a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we take 90 away from 90, we end up with 0.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 10

Let's proceed to step 3:
The number 10 fits into 9 0 times, leaving a remainder of 9.
The next digit of our result is 0. 
Result so far: 90.0
If we take 0 away from 9, we end up with 9.
Bring next digit (4) of the dividend behind the 9 and repeat the process: 94 / 10

On to step 4:
When dividing 94 by 10, we get 9 with a remainder of 4.
Write down 9 as next digit of the result. 
Result so far: 909.0
If we subtract 90 from 94, we get 4.
Grab the next digit (8) from the dividend, add it to 4, then carry on: 48 / 10

Going ahead to step 5:
10 goes into 48 4 times with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 9094.0
Subtract 40 from 48 to get 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 10

Going ahead to step 6:
If we divide 81 by 10, we get 8 and a remainder of 1.
Put 8 as the next digit of the answer. 
Result so far: 90948.0
Subtracting 80 from 81 leaves us with 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 10

Advancing to step 7:
17 divided by 10 is 1 with a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 909481.0
Deduct 10 from 17 and we're left with 7.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 10

Let's proceed to step 8:
10 can be fit into 71 7 times, resulting in a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 9094817.0
If we subtract 70 from 71, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 9:
The number 10 fits into 10 1 times, leaving a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 9094817.1
Subtract 10 from 10 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 10:
10 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 9094817.1
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 11:
10 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 9094817.1
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 9094817.1 with a remainder of 0.0.
