99831584 divided by 170 
We want to divide 99831584 by 170.

Let's proceed to step 1:
170 goes into 9 0 times with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 170

Let's proceed to step 2:
170 goes into 99 0 times with a remainder of 99.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 99 after subtracting 0 from 99.
Bring next digit (8) of the dividend behind the 99 and repeat the process: 998 / 170

Step 3:
170 goes into 998 5 times with a remainder of 148.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we take 850 away from 998, we end up with 148.
Grab the next digit (3) from the dividend, add it to 148, then carry on: 1483 / 170

Moving on to step 4:
If we divide 1483 by 170, we get 8 and a remainder of 123.
Record the quotient 8 as the next digit in the result. 
Result so far: 58.0
Subtracting 1360 from 1483 leaves us with 123.
Append the next digit (1) from the dividend to 123 and continue with: 1231 / 170

Step 5:
If we divide 1231 by 170, we get 7 and a remainder of 41.
Use 7 as the next digit of our solution. 
Result so far: 587.0
If we subtract 1190 from 1231, we get 41.
Bring next digit (5) of the dividend behind the 41 and repeat the process: 415 / 170

On to step 6:
If we divide 415 by 170, we get 2 and a remainder of 75.
The next digit of our result is 2. 
Result so far: 5872.0
If we take 340 away from 415, we end up with 75.
Take the next digit (8) from the dividend and append it to 75, then repeat: 758 / 170

Step 7:
When dividing 758 by 170, we get 4 with a remainder of 78.
Put 4 as the next digit of the answer. 
Result so far: 58724.0
Subtracting 680 from 758 leaves us with 78.
Grab the next digit (4) from the dividend, add it to 78, then carry on: 784 / 170

Moving on to step 8:
784 divided by 170 is 4 with a remainder of 104.
Put 4 as the next digit of the answer. 
Result so far: 587244.0
If we take 680 away from 784, we end up with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Step 9:
170 can be fit into 1040 6 times, resulting in a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 587244.6
If we subtract 1020 from 1040, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 10:
If we divide 200 by 170, we get 1 and a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 587244.61
Subtract 170 from 200 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 11:
170 can be fit into 300 1 times, resulting in a remainder of 130.
Put 1 as the next digit of the answer. 
Result so far: 587244.611
Deduct 170 from 300 and we're left with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

The final outcome is 587244.611, with a leftover of 0.013.
