40174 ÷ 90 
We're looking to find how many times 90 goes into 40174.

Moving on to step 1:
90 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 90

Moving on to step 2:
When dividing 40 by 90, we get 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 40 and we're left with 40.
Grab the next digit (1) from the dividend, add it to 40, then carry on: 401 / 90

Going ahead to step 3:
When dividing 401 by 90, we get 4 with a remainder of 41.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 41 after subtracting 360 from 401.
Grab the next digit (7) from the dividend, add it to 41, then carry on: 417 / 90

Moving on to step 4:
The number 90 fits into 417 4 times, leaving a remainder of 57.
Record the quotient 4 as the next digit in the result. 
Result so far: 44.0
If we subtract 360 from 417, we get 57.
Take the next digit (4) from the dividend and append it to 57, then repeat: 574 / 90

Advancing to step 5:
574 divided by 90 is 6 with a remainder of 34.
Record the quotient 6 as the next digit in the result. 
Result so far: 446.0
Deduct 540 from 574 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 6:
If we divide 340 by 90, we get 3 and a remainder of 70.
Record the quotient 3 as the next digit in the result. 
Result so far: 446.3
Subtract 270 from 340 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 7:
90 can be fit into 700 7 times, resulting in a remainder of 70.
Put 7 as the next digit of the answer. 
Result so far: 446.37
If we take 630 away from 700, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 8:
If we divide 700 by 90, we get 7 and a remainder of 70.
The next digit of our result is 7. 
Result so far: 446.377
Subtract 630 from 700 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

After the division, we end up with 446.377 and a remainder of 0.007.
