120816 divided by 86 
We want to divide 120816 by 86.

Let's proceed to step 1:
1 divided by 86 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 86

Step 2:
If we divide 12 by 86, we get 0 and a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Grab the next digit (0) from the dividend, add it to 12, then carry on: 120 / 86

On to step 3:
The number 86 fits into 120 1 times, leaving a remainder of 34.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 86 from 120 leaves us with 34.
Include the next digit (8) from the dividend after 34, then repeat: 348 / 86

Let's proceed to step 4:
If we divide 348 by 86, we get 4 and a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 14.0
Subtracting 344 from 348 leaves us with 4.
Bring next digit (1) of the dividend behind the 4 and repeat the process: 41 / 86

Step 5:
41 divided by 86 is 0 with a remainder of 41.
The next digit of our result is 0. 
Result so far: 140.0
Subtract 0 from 41 to get 41.
Fetch the next digit (6) from the dividend, attach it to 41 and continue: 416 / 86

Going ahead to step 6:
The number 86 fits into 416 4 times, leaving a remainder of 72.
Record the quotient 4 as the next digit in the result. 
Result so far: 1404.0
Subtract 344 from 416 to 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.

Let's proceed to step 7:
720 divided by 86 is 8 with a remainder of 32.
Write down 8 as next digit of the result. 
Result so far: 1404.8
The remainder is 32 after subtracting 688 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 8:
The number 86 fits into 320 3 times, leaving a remainder of 62.
Record the quotient 3 as the next digit in the result. 
Result so far: 1404.83
If we subtract 258 from 320, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 9:
620 divided by 86 is 7 with a remainder of 18.
Put 7 as the next digit of the answer. 
Result so far: 1404.837
If we take 602 away from 620, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 10:
180 divided by 86 is 2 with a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 1404.8372
Subtract 172 from 180 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 11:
80 divided by 86 is 0 with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 1404.8372
Subtracting 0 from 80 leaves us 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.

Advancing to step 12:
When dividing 800 by 86, we get 9 with a remainder of 26.
Put 9 as the next digit of the answer. 
Result so far: 1404.837209
Subtracting 774 from 800 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 13:
260 divided by 86 is 3 with a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 1404.8372093
Subtract 258 from 260 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 14:
If we divide 20 by 86, we get 0 and a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 1404.8372093
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

After the division, we end up with 1404.8372093 and a remainder of 2e-08.
