90239997 divided by 155 
Let's see how many times 155 fits into 90239997.

Moving on to step 1:
The number 155 fits into 9 0 times, leaving a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 155

Step 2:
155 goes into 90 0 times with a remainder of 90.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 90 after subtracting 0 from 90.
Append the next digit (2) from the dividend to 90 and continue with: 902 / 155

Step 3:
155 goes into 902 5 times with a remainder of 127.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
The remainder is 127 after subtracting 775 from 902.
Include the next digit (3) from the dividend after 127, then repeat: 1273 / 155

Let's proceed to step 4:
If we divide 1273 by 155, we get 8 and a remainder of 33.
Put 8 as the next digit of the answer. 
Result so far: 58.0
If we take 1240 away from 1273, we end up with 33.
Bring next digit (9) of the dividend behind the 33 and repeat the process: 339 / 155

On to step 5:
339 divided by 155 is 2 with a remainder of 29.
Write down 2 as next digit of the result. 
Result so far: 582.0
If we subtract 310 from 339, we get 29.
Grab the next digit (9) from the dividend, add it to 29, then carry on: 299 / 155

Advancing to step 6:
155 goes into 299 1 times with a remainder of 144.
Write down 1 as next digit of the result. 
Result so far: 5821.0
If we take 155 away from 299, we end up with 144.
Include the next digit (9) from the dividend after 144, then repeat: 1449 / 155

Moving on to step 7:
If we divide 1449 by 155, we get 9 and a remainder of 54.
Write down 9 as next digit of the result. 
Result so far: 58219.0
The remainder is 54 after subtracting 1395 from 1449.
Grab the next digit (7) from the dividend, add it to 54, then carry on: 547 / 155

Step 8:
The number 155 fits into 547 3 times, leaving a remainder of 82.
Record the quotient 3 as the next digit in the result. 
Result so far: 582193.0
Deduct 465 from 547 and we're left with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

On to step 9:
155 goes into 820 5 times with a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 582193.5
Deduct 775 from 820 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 10:
155 goes into 450 2 times with a remainder of 140.
Put 2 as the next digit of the answer. 
Result so far: 582193.52
If we subtract 310 from 450, we get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Moving on to step 11:
155 goes into 1400 9 times with a remainder of 5.
Record the quotient 9 as the next digit in the result. 
Result so far: 582193.529
Subtracting 1395 from 1400 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 12:
50 divided by 155 is 0 with a remainder of 50.
The next digit of our result is 0. 
Result so far: 582193.529
If we take 0 away from 50, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 13:
The number 155 fits into 500 3 times, leaving a remainder of 35.
Write down 3 as next digit of the result. 
Result so far: 582193.52903
The remainder is 35 after subtracting 465 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 14:
When dividing 350 by 155, we get 2 with a remainder of 40.
Write down 2 as next digit of the result. 
Result so far: 582193.529032
Deduct 310 from 350 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 15:
400 divided by 155 is 2 with a remainder of 90.
Write down 2 as next digit of the result. 
Result so far: 582193.5290322
If we take 310 away from 400, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

The final result is 582193.5290322 with a remainder of 9e-07.
