Let's divide 90193384 by 171
Let's see how many times 171 fits into 90193384.

Step 1:
9 divided by 171 is 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 171

Step 2:
The number 171 fits into 90 0 times, leaving a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 90 leaves us with 90.
Take the next digit (1) from the dividend and append it to 90, then repeat: 901 / 171

Step 3:
If we divide 901 by 171, we get 5 and a remainder of 46.
The next digit of our result is 5. 
Result so far: 5.0
If we subtract 855 from 901, we get 46.
Fetch the next digit (9) from the dividend, attach it to 46 and continue: 469 / 171

Going ahead to step 4:
171 can be fit into 469 2 times, resulting in a remainder of 127.
Write down 2 as next digit of the result. 
Result so far: 52.0
Subtract 342 from 469 to get 127.
Append the next digit (3) from the dividend to 127 and continue with: 1273 / 171

Step 5:
171 goes into 1273 7 times with a remainder of 76.
Write down 7 as next digit of the result. 
Result so far: 527.0
Subtract 1197 from 1273 to get 76.
Fetch the next digit (3) from the dividend, attach it to 76 and continue: 763 / 171

Advancing to step 6:
If we divide 763 by 171, we get 4 and a remainder of 79.
The number 4 becomes the next digit in our result. 
Result so far: 5274.0
The remainder is 79 after subtracting 684 from 763.
Fetch the next digit (8) from the dividend, attach it to 79 and continue: 798 / 171

Advancing to step 7:
The number 171 fits into 798 4 times, leaving a remainder of 114.
The number 4 becomes the next digit in our result. 
Result so far: 52744.0
If we take 684 away from 798, we end up with 114.
Bring next digit (4) of the dividend behind the 114 and repeat the process: 1144 / 171

Step 8:
When dividing 1144 by 171, we get 6 with a remainder of 118.
The next digit of our result is 6. 
Result so far: 527446.0
Deduct 1026 from 1144 and we're left with 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Let's proceed to step 9:
If we divide 1180 by 171, we get 6 and a remainder of 154.
Put 6 as the next digit of the answer. 
Result so far: 527446.6
The remainder is 154 after subtracting 1026 from 1180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

On to step 10:
When dividing 1540 by 171, we get 9 with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 527446.69
If we take 1539 away from 1540, 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.

Moving on to step 11:
171 goes into 10 0 times with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 527446.69
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 12:
100 divided by 171 is 0 with a remainder of 100.
The next digit of our result is 0. 
Result so far: 527446.69
Subtract 0 from 100 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The final result is 527446.69 with a remainder of 0.001.
