We look at the division of 99887159 by 538 
Our goal is to divide 99887159 by 538.

On to step 1:
If we divide 9 by 538, we get 0 and a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 538

Advancing to step 2:
When dividing 99 by 538, we get 0 with a remainder of 99.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 99 to get 99.
Append the next digit (8) from the dividend to 99 and continue with: 998 / 538

Moving on to step 3:
If we divide 998 by 538, we get 1 and a remainder of 460.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 460 after subtracting 538 from 998.
Include the next digit (8) from the dividend after 460, then repeat: 4608 / 538

On to step 4:
538 can be fit into 4608 8 times, resulting in a remainder of 304.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
Deduct 4304 from 4608 and we're left with 304.
Fetch the next digit (7) from the dividend, attach it to 304 and continue: 3047 / 538

Advancing to step 5:
538 goes into 3047 5 times with a remainder of 357.
Use 5 as the next digit of our solution. 
Result so far: 185.0
Subtracting 2690 from 3047 leaves us with 357.
Grab the next digit (1) from the dividend, add it to 357, then carry on: 3571 / 538

Let's proceed to step 6:
When dividing 3571 by 538, we get 6 with a remainder of 343.
Use 6 as the next digit of our solution. 
Result so far: 1856.0
Subtracting 3228 from 3571 leaves us with 343.
Fetch the next digit (5) from the dividend, attach it to 343 and continue: 3435 / 538

On to step 7:
The number 538 fits into 3435 6 times, leaving a remainder of 207.
Record the quotient 6 as the next digit in the result. 
Result so far: 18566.0
Subtracting 3228 from 3435 leaves us with 207.
Fetch the next digit (9) from the dividend, attach it to 207 and continue: 2079 / 538

On to step 8:
If we divide 2079 by 538, we get 3 and a remainder of 465.
The number 3 becomes the next digit in our result. 
Result so far: 185663.0
If we subtract 1614 from 2079, we get 465.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4650, and continue the process.

Advancing to step 9:
The number 538 fits into 4650 8 times, leaving a remainder of 346.
Put 8 as the next digit of the answer. 
Result so far: 185663.8
The remainder is 346 after subtracting 4304 from 4650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

Let's proceed to step 10:
When dividing 3460 by 538, we get 6 with a remainder of 232.
Use 6 as the next digit of our solution. 
Result so far: 185663.86
The remainder is 232 after subtracting 3228 from 3460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Going ahead to step 11:
When dividing 2320 by 538, we get 4 with a remainder of 168.
Write down 4 as next digit of the result. 
Result so far: 185663.864
The remainder is 168 after subtracting 2152 from 2320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Moving on to step 12:
The number 538 fits into 1680 3 times, leaving a remainder of 66.
The next digit of our result is 3. 
Result so far: 185663.8643
If we take 1614 away from 1680, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 13:
538 goes into 660 1 times with a remainder of 122.
Use 1 as the next digit of our solution. 
Result so far: 185663.86431
If we subtract 538 from 660, we get 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Going ahead to step 14:
1220 divided by 538 is 2 with a remainder of 144.
Put 2 as the next digit of the answer. 
Result so far: 185663.864312
If we subtract 1076 from 1220, we get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Moving on to step 15:
1440 divided by 538 is 2 with a remainder of 364.
Put 2 as the next digit of the answer. 
Result so far: 185663.8643122
Deduct 1076 from 1440 and we're left with 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

The final outcome is 185663.8643122, with a leftover of 3.64e-06.
