We look at the division of 168339 by 87 
We want to divide 168339 by 87.

Step 1:
The number 87 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 87

Advancing to step 2:
87 can be fit into 16 0 times, resulting in a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 16 and we're left with 16.
Fetch the next digit (8) from the dividend, attach it to 16 and continue: 168 / 87

Advancing to step 3:
When dividing 168 by 87, we get 1 with a remainder of 81.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 87 from 168 leaves us with 81.
Grab the next digit (3) from the dividend, add it to 81, then carry on: 813 / 87

On to step 4:
If we divide 813 by 87, we get 9 and a remainder of 30.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
The remainder is 30 after subtracting 783 from 813.
Take the next digit (3) from the dividend and append it to 30, then repeat: 303 / 87

On to step 5:
87 goes into 303 3 times with a remainder of 42.
The number 3 becomes the next digit in our result. 
Result so far: 193.0
Deduct 261 from 303 and we're left with 42.
Grab the next digit (9) from the dividend, add it to 42, then carry on: 429 / 87

Step 6:
87 can be fit into 429 4 times, resulting in a remainder of 81.
Put 4 as the next digit of the answer. 
Result so far: 1934.0
Deduct 348 from 429 and we're left with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Going ahead to step 7:
87 goes into 810 9 times with a remainder of 27.
Record the quotient 9 as the next digit in the result. 
Result so far: 1934.9
Deduct 783 from 810 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 8:
The number 87 fits into 270 3 times, leaving a remainder of 9.
Record the quotient 3 as the next digit in the result. 
Result so far: 1934.93
Subtract 261 from 270 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 9:
When dividing 90 by 87, we get 1 with a remainder of 3.
The next digit of our result is 1. 
Result so far: 1934.931
Subtract 87 from 90 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 10:
30 divided by 87 is 0 with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 1934.931
Subtract 0 from 30 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.

Moving on to step 11:
If we divide 300 by 87, we get 3 and a remainder of 39.
Use 3 as the next digit of our solution. 
Result so far: 1934.93103
If we subtract 261 from 300, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 12:
87 can be fit into 390 4 times, resulting in a remainder of 42.
Use 4 as the next digit of our solution. 
Result so far: 1934.931034
Subtracting 348 from 390 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 13:
The number 87 fits into 420 4 times, leaving a remainder of 72.
Record the quotient 4 as the next digit in the result. 
Result so far: 1934.9310344
If we subtract 348 from 420, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

The final outcome is 1934.9310344, with a leftover of 7.2e-07.
