Let's divide 121039 by 86
We're looking to find how many times 86 goes into 121039.

On 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
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 86

Going ahead to step 2:
12 divided by 86 is 0 with a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Include the next digit (1) from the dividend after 12, then repeat: 121 / 86

Let's proceed to step 3:
If we divide 121 by 86, we get 1 and a remainder of 35.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 86 from 121 to get 35.
Take the next digit (0) from the dividend and append it to 35, then repeat: 350 / 86

Moving on to step 4:
86 can be fit into 350 4 times, resulting in a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 14.0
If we take 344 away from 350, we end up with 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 86

On to step 5:
86 goes into 63 0 times with a remainder of 63.
Put 0 as the next digit of the answer. 
Result so far: 140.0
Subtracting 0 from 63 leaves us with 63.
Take the next digit (9) from the dividend and append it to 63, then repeat: 639 / 86

Step 6:
86 goes into 639 7 times with a remainder of 37.
Use 7 as the next digit of our solution. 
Result so far: 1407.0
Subtract 602 from 639 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 7:
86 can be fit into 370 4 times, resulting in a remainder of 26.
Put 4 as the next digit of the answer. 
Result so far: 1407.4
Subtract 344 from 370 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 8:
When dividing 260 by 86, we get 3 with a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 1407.43
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.

Let's proceed to step 9:
20 divided by 86 is 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 1407.43
If we take 0 away from 20, we end up 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.

Advancing to step 10:
200 divided by 86 is 2 with a remainder of 28.
Use 2 as the next digit of our solution. 
Result so far: 1407.4302
The remainder is 28 after subtracting 172 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 11:
The number 86 fits into 280 3 times, leaving a remainder of 22.
Record the quotient 3 as the next digit in the result. 
Result so far: 1407.43023
Deduct 258 from 280 and we're left with 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 12:
When dividing 220 by 86, we get 2 with a remainder of 48.
Use 2 as the next digit of our solution. 
Result so far: 1407.430232
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.

Moving on to step 13:
480 divided by 86 is 5 with a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 1407.4302325
The remainder is 50 after subtracting 430 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 14:
When dividing 500 by 86, we get 5 with a remainder of 70.
The next digit of our result is 5. 
Result so far: 1407.43023255
If we subtract 430 from 500, we 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.

In conclusion, the division gives 1407.43023255 with a balance of 7e-08.
