Let's divide 242121 by 86
We're looking to find how many times 86 goes into 242121.

Going ahead to step 1:
When dividing 2 by 86, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (4) from the dividend to 2 and continue with: 24 / 86

Let's proceed to step 2:
When dividing 24 by 86, we get 0 with a remainder of 24.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 24 and we're left with 24.
Fetch the next digit (2) from the dividend, attach it to 24 and continue: 242 / 86

Let's proceed to step 3:
The number 86 fits into 242 2 times, leaving a remainder of 70.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 172 from 242 leaves us with 70.
Append the next digit (1) from the dividend to 70 and continue with: 701 / 86

Going ahead to step 4:
86 goes into 701 8 times with a remainder of 13.
The next digit of our result is 8. 
Result so far: 28.0
Subtract 688 from 701 to get 13.
Append the next digit (2) from the dividend to 13 and continue with: 132 / 86

Going ahead to step 5:
The number 86 fits into 132 1 times, leaving a remainder of 46.
The number 1 becomes the next digit in our result. 
Result so far: 281.0
The remainder is 46 after subtracting 86 from 132.
Append the next digit (1) from the dividend to 46 and continue with: 461 / 86

Moving on to step 6:
86 can be fit into 461 5 times, resulting in a remainder of 31.
Use 5 as the next digit of our solution. 
Result so far: 2815.0
Subtracting 430 from 461 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 7:
If we divide 310 by 86, we get 3 and a remainder of 52.
Record the quotient 3 as the next digit in the result. 
Result so far: 2815.3
Subtracting 258 from 310 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 8:
When dividing 520 by 86, we get 6 with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 2815.36
The remainder is 4 after subtracting 516 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 9:
When dividing 40 by 86, we get 0 with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 2815.36
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 10:
400 divided by 86 is 4 with a remainder of 56.
Record the quotient 4 as the next digit in the result. 
Result so far: 2815.3604
If we subtract 344 from 400, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 11:
When dividing 560 by 86, we get 6 with a remainder of 44.
The number 6 becomes the next digit in our result. 
Result so far: 2815.36046
The remainder is 44 after subtracting 516 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 12:
440 divided by 86 is 5 with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 2815.360465
If we take 430 away from 440, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 13:
100 divided by 86 is 1 with a remainder of 14.
Write down 1 as next digit of the result. 
Result so far: 2815.3604651
If we subtract 86 from 100, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 14:
When dividing 140 by 86, we get 1 with a remainder of 54.
The next digit of our result is 1. 
Result so far: 2815.36046511
Deduct 86 from 140 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Our division results in 2815.36046511 with a remaining 5.4e-08.
