12160 divided by 86 
We want to figure out the number of times 12160 can be divided by 86.

Going ahead to step 1:
86 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 86

Moving on to step 2:
The number 86 fits into 12 0 times, leaving a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Take the next digit (1) from the dividend and append it to 12, then repeat: 121 / 86

On to step 3:
When dividing 121 by 86, we get 1 with a remainder of 35.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 86 away from 121, we end up with 35.
Grab the next digit (6) from the dividend, add it to 35, then carry on: 356 / 86

Going ahead to step 4:
The number 86 fits into 356 4 times, leaving a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Subtract 344 from 356 to get 12.
Fetch the next digit (0) from the dividend, attach it to 12 and continue: 120 / 86

Advancing to step 5:
If we divide 120 by 86, we get 1 and a remainder of 34.
Use 1 as the next digit of our solution. 
Result so far: 141.0
The remainder is 34 after subtracting 86 from 120.
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 6:
340 divided by 86 is 3 with a remainder of 82.
Put 3 as the next digit of the answer. 
Result so far: 141.3
If we take 258 away from 340, we end up with 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 7:
86 can be fit into 820 9 times, resulting in a remainder of 46.
Record the quotient 9 as the next digit in the result. 
Result so far: 141.39
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.

Moving on to step 8:
If we divide 460 by 86, we get 5 and a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 141.395
The remainder is 30 after subtracting 430 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 9:
86 goes into 300 3 times with a remainder of 42.
The next digit of our result is 3. 
Result so far: 141.3953
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.

Advancing to step 10:
The number 86 fits into 420 4 times, leaving a remainder of 76.
The next digit of our result is 4. 
Result so far: 141.39534
If we take 344 away from 420, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 11:
If we divide 760 by 86, we get 8 and a remainder of 72.
The next digit of our result is 8. 
Result so far: 141.395348
Subtracting 688 from 760 leaves us with 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 12:
86 can be fit into 720 8 times, resulting in a remainder of 32.
The number 8 becomes the next digit in our result. 
Result so far: 141.3953488
Subtracting 688 from 720 leaves us 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.

The quotient of the division is 141.3953488, and the remainder is 3.2e-07.
