We look at the division of 90139933 by 598 
Let's see how many times 598 fits into 90139933.

Step 1:
When dividing 9 by 598, we get 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 598

On to step 2:
598 can be fit into 90 0 times, resulting in a remainder of 90.
The next digit of our result is 0. 
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 / 598

Advancing to step 3:
598 goes into 901 1 times with a remainder of 303.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 598 from 901, we get 303.
Take the next digit (3) from the dividend and append it to 303, then repeat: 3033 / 598

Let's proceed to step 4:
598 can be fit into 3033 5 times, resulting in a remainder of 43.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Subtracting 2990 from 3033 leaves us with 43.
Append the next digit (9) from the dividend to 43 and continue with: 439 / 598

Let's proceed to step 5:
598 goes into 439 0 times with a remainder of 439.
The number 0 becomes the next digit in our result. 
Result so far: 150.0
The remainder is 439 after subtracting 0 from 439.
Take the next digit (9) from the dividend and append it to 439, then repeat: 4399 / 598

On to step 6:
The number 598 fits into 4399 7 times, leaving a remainder of 213.
The next digit of our result is 7. 
Result so far: 1507.0
If we take 4186 away from 4399, we end up with 213.
Fetch the next digit (3) from the dividend, attach it to 213 and continue: 2133 / 598

Moving on to step 7:
If we divide 2133 by 598, we get 3 and a remainder of 339.
Put 3 as the next digit of the answer. 
Result so far: 15073.0
If we take 1794 away from 2133, we end up with 339.
Bring next digit (3) of the dividend behind the 339 and repeat the process: 3393 / 598

On to step 8:
The number 598 fits into 3393 5 times, leaving a remainder of 403.
Record the quotient 5 as the next digit in the result. 
Result so far: 150735.0
Subtracting 2990 from 3393 leaves us with 403.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4030, and continue the process.

On to step 9:
598 can be fit into 4030 6 times, resulting in a remainder of 442.
Put 6 as the next digit of the answer. 
Result so far: 150735.6
Subtract 3588 from 4030 to get 442.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4420, and continue the process.

On to step 10:
598 goes into 4420 7 times with a remainder of 234.
Write down 7 as next digit of the result. 
Result so far: 150735.67
If we subtract 4186 from 4420, we get 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Moving on to step 11:
The number 598 fits into 2340 3 times, leaving a remainder of 546.
The next digit of our result is 3. 
Result so far: 150735.673
The remainder is 546 after subtracting 1794 from 2340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5460, and continue the process.

Going ahead to step 12:
598 can be fit into 5460 9 times, resulting in a remainder of 78.
The next digit of our result is 9. 
Result so far: 150735.6739
The remainder is 78 after subtracting 5382 from 5460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Step 13:
780 divided by 598 is 1 with a remainder of 182.
The number 1 becomes the next digit in our result. 
Result so far: 150735.67391
Deduct 598 from 780 and we're left with 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

On to step 14:
598 can be fit into 1820 3 times, resulting in a remainder of 26.
The number 3 becomes the next digit in our result. 
Result so far: 150735.673913
Subtract 1794 from 1820 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 15:
598 goes into 260 0 times with a remainder of 260.
Use 0 as the next digit of our solution. 
Result so far: 150735.673913
If we subtract 0 from 260, we get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Let's proceed to step 16:
2600 divided by 598 is 4 with a remainder of 208.
The number 4 becomes the next digit in our result. 
Result so far: 150735.67391304
The remainder is 208 after subtracting 2392 from 2600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

The final outcome is 150735.67391304, with a leftover of 2.08e-07.
