120434 divided by 86 
Let's see how many times 86 fits into 120434.

Advancing to step 1:
86 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 86

Let's proceed to step 2:
If we divide 12 by 86, we get 0 and a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Grab the next digit (0) from the dividend, add it to 12, then carry on: 120 / 86

Advancing to step 3:
120 divided by 86 is 1 with a remainder of 34.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 86 from 120 to get 34.
Append the next digit (4) from the dividend to 34 and continue with: 344 / 86

Moving on to step 4:
The number 86 fits into 344 4 times, leaving a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
If we subtract 344 from 344, we get 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 86

Going ahead to step 5:
The number 86 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 140.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (4) from the dividend, attach it to 3 and continue: 34 / 86

Going ahead to step 6:
The number 86 fits into 34 0 times, leaving a remainder of 34.
The next digit of our result is 0. 
Result so far: 1400.0
Subtract 0 from 34 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 7:
86 can be fit into 340 3 times, resulting in a remainder of 82.
Record the quotient 3 as the next digit in the result. 
Result so far: 1400.3
Subtract 258 from 340 to get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Step 8:
86 can be fit into 820 9 times, resulting in a remainder of 46.
The number 9 becomes the next digit in our result. 
Result so far: 1400.39
Deduct 774 from 820 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 9:
86 can be fit into 460 5 times, resulting in a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 1400.395
If we subtract 430 from 460, we 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 10:
When dividing 300 by 86, we get 3 with a remainder of 42.
Record the quotient 3 as the next digit in the result. 
Result so far: 1400.3953
Deduct 258 from 300 and we're left 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.

Moving on to step 11:
420 divided by 86 is 4 with a remainder of 76.
Use 4 as the next digit of our solution. 
Result so far: 1400.39534
Subtract 344 from 420 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

On to step 12:
The number 86 fits into 760 8 times, leaving a remainder of 72.
The next digit of our result is 8. 
Result so far: 1400.395348
Subtract 688 from 760 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.

Moving on to step 13:
When dividing 720 by 86, we get 8 with a remainder of 32.
Write down 8 as next digit of the result. 
Result so far: 1400.3953488
Deduct 688 from 720 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Our division results in 1400.3953488 with a remaining 3.2e-07.
