We're dividing 118639 by 86 
Our goal is to divide 118639 by 86.

Let's proceed to step 1:
The number 86 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (1) from the dividend, add it to 1, then carry on: 11 / 86

Advancing to step 2:
If we divide 11 by 86, we get 0 and a remainder of 11.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 11, we get 11.
Include the next digit (8) from the dividend after 11, then repeat: 118 / 86

On to step 3:
86 can be fit into 118 1 times, resulting in a remainder of 32.
The next digit of our result is 1. 
Result so far: 1.0
If we take 86 away from 118, we end up with 32.
Bring next digit (6) of the dividend behind the 32 and repeat the process: 326 / 86

Going ahead to step 4:
When dividing 326 by 86, we get 3 with a remainder of 68.
The next digit of our result is 3. 
Result so far: 13.0
Deduct 258 from 326 and we're left with 68.
Include the next digit (3) from the dividend after 68, then repeat: 683 / 86

Moving on to step 5:
When dividing 683 by 86, we get 7 with a remainder of 81.
Record the quotient 7 as the next digit in the result. 
Result so far: 137.0
Deduct 602 from 683 and we're left with 81.
Append the next digit (9) from the dividend to 81 and continue with: 819 / 86

Let's proceed to step 6:
86 can be fit into 819 9 times, resulting in a remainder of 45.
Write down 9 as next digit of the result. 
Result so far: 1379.0
The remainder is 45 after subtracting 774 from 819.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 7:
450 divided by 86 is 5 with a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 1379.5
The remainder is 20 after subtracting 430 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 8:
86 goes into 200 2 times with a remainder of 28.
The next digit of our result is 2. 
Result so far: 1379.52
If we subtract 172 from 200, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 9:
86 goes into 280 3 times with a remainder of 22.
Write down 3 as next digit of the result. 
Result so far: 1379.523
If we subtract 258 from 280, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 10:
86 goes into 220 2 times with a remainder of 48.
The next digit of our result is 2. 
Result so far: 1379.5232
If we subtract 172 from 220, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 11:
480 divided by 86 is 5 with a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 1379.52325
Deduct 430 from 480 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 12:
If we divide 500 by 86, we get 5 and a remainder of 70.
Record the quotient 5 as the next digit in the result. 
Result so far: 1379.523255
Subtract 430 from 500 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

After the division, we end up with 1379.523255 and a remainder of 7e-06.
