We're dividing 83870915 by 598 
Let's see how many times 598 fits into 83870915.

On to step 1:
598 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (3) from the dividend, attach it to 8 and continue: 83 / 598

On to step 2:
The number 598 fits into 83 0 times, leaving a remainder of 83.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 83 after subtracting 0 from 83.
Bring next digit (8) of the dividend behind the 83 and repeat the process: 838 / 598

Going ahead to step 3:
598 can be fit into 838 1 times, resulting in a remainder of 240.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 598 from 838 leaves us with 240.
Bring next digit (7) of the dividend behind the 240 and repeat the process: 2407 / 598

Going ahead to step 4:
The number 598 fits into 2407 4 times, leaving a remainder of 15.
The next digit of our result is 4. 
Result so far: 14.0
If we subtract 2392 from 2407, we get 15.
Grab the next digit (0) from the dividend, add it to 15, then carry on: 150 / 598

Advancing to step 5:
598 can be fit into 150 0 times, resulting in a remainder of 150.
Use 0 as the next digit of our solution. 
Result so far: 140.0
Deduct 0 from 150 and we're left with 150.
Append the next digit (9) from the dividend to 150 and continue with: 1509 / 598

Step 6:
598 can be fit into 1509 2 times, resulting in a remainder of 313.
Use 2 as the next digit of our solution. 
Result so far: 1402.0
Deduct 1196 from 1509 and we're left with 313.
Bring next digit (1) of the dividend behind the 313 and repeat the process: 3131 / 598

Moving on to step 7:
The number 598 fits into 3131 5 times, leaving a remainder of 141.
Use 5 as the next digit of our solution. 
Result so far: 14025.0
Subtracting 2990 from 3131 leaves us with 141.
Grab the next digit (5) from the dividend, add it to 141, then carry on: 1415 / 598

Moving on to step 8:
1415 divided by 598 is 2 with a remainder of 219.
The number 2 becomes the next digit in our result. 
Result so far: 140252.0
The remainder is 219 after subtracting 1196 from 1415.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2190, and continue the process.

Advancing to step 9:
The number 598 fits into 2190 3 times, leaving a remainder of 396.
Use 3 as the next digit of our solution. 
Result so far: 140252.3
Subtracting 1794 from 2190 leaves us with 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Let's proceed to step 10:
When dividing 3960 by 598, we get 6 with a remainder of 372.
Use 6 as the next digit of our solution. 
Result so far: 140252.36
Subtract 3588 from 3960 to get 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Step 11:
The number 598 fits into 3720 6 times, leaving a remainder of 132.
Put 6 as the next digit of the answer. 
Result so far: 140252.366
Subtract 3588 from 3720 to get 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

The final result is 140252.366 with a remainder of 0.0132.
