We look at the division of 86860255 by 608 
We want to divide 86860255 by 608.

Going ahead to step 1:
The number 608 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 608

Let's proceed to step 2:
When dividing 86 by 608, we get 0 with a remainder of 86.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 86, we get 86.
Include the next digit (8) from the dividend after 86, then repeat: 868 / 608

Step 3:
The number 608 fits into 868 1 times, leaving a remainder of 260.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 608 from 868 and we're left with 260.
Fetch the next digit (6) from the dividend, attach it to 260 and continue: 2606 / 608

On to step 4:
The number 608 fits into 2606 4 times, leaving a remainder of 174.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Subtract 2432 from 2606 to get 174.
Take the next digit (0) from the dividend and append it to 174, then repeat: 1740 / 608

Let's proceed to step 5:
The number 608 fits into 1740 2 times, leaving a remainder of 524.
The next digit of our result is 2. 
Result so far: 142.0
If we subtract 1216 from 1740, we get 524.
Fetch the next digit (2) from the dividend, attach it to 524 and continue: 5242 / 608

Moving on to step 6:
When dividing 5242 by 608, we get 8 with a remainder of 378.
Use 8 as the next digit of our solution. 
Result so far: 1428.0
The remainder is 378 after subtracting 4864 from 5242.
Append the next digit (5) from the dividend to 378 and continue with: 3785 / 608

Moving on to step 7:
608 goes into 3785 6 times with a remainder of 137.
Record the quotient 6 as the next digit in the result. 
Result so far: 14286.0
Subtract 3648 from 3785 to get 137.
Append the next digit (5) from the dividend to 137 and continue with: 1375 / 608

Let's proceed to step 8:
If we divide 1375 by 608, we get 2 and a remainder of 159.
Use 2 as the next digit of our solution. 
Result so far: 142862.0
If we subtract 1216 from 1375, we get 159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

Step 9:
1590 divided by 608 is 2 with a remainder of 374.
Use 2 as the next digit of our solution. 
Result so far: 142862.2
If we subtract 1216 from 1590, we get 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

Let's proceed to step 10:
608 can be fit into 3740 6 times, resulting in a remainder of 92.
Write down 6 as next digit of the result. 
Result so far: 142862.26
If we subtract 3648 from 3740, we get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Going ahead to step 11:
920 divided by 608 is 1 with a remainder of 312.
Write down 1 as next digit of the result. 
Result so far: 142862.261
Deduct 608 from 920 and we're left with 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Let's proceed to step 12:
If we divide 3120 by 608, we get 5 and a remainder of 80.
Write down 5 as next digit of the result. 
Result so far: 142862.2615
If we take 3040 away from 3120, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 13:
The number 608 fits into 800 1 times, leaving a remainder of 192.
Use 1 as the next digit of our solution. 
Result so far: 142862.26151
Deduct 608 from 800 and we're left with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

On to step 14:
If we divide 1920 by 608, we get 3 and a remainder of 96.
Record the quotient 3 as the next digit in the result. 
Result so far: 142862.261513
Deduct 1824 from 1920 and we're left with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

On to step 15:
608 goes into 960 1 times with a remainder of 352.
Put 1 as the next digit of the answer. 
Result so far: 142862.2615131
If we subtract 608 from 960, we get 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Advancing to step 16:
608 can be fit into 3520 5 times, resulting in a remainder of 480.
The number 5 becomes the next digit in our result. 
Result so far: 142862.26151315
If we subtract 3040 from 3520, we get 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

The final outcome is 142862.26151315, with a leftover of 4.8e-07.
