Let's divide 86584891 by 342
We want to divide 86584891 by 342.

Let's proceed to step 1:
342 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 342

Step 2:
The number 342 fits into 86 0 times, leaving a remainder of 86.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 86 and we're left with 86.
Take the next digit (5) from the dividend and append it to 86, then repeat: 865 / 342

Let's proceed to step 3:
If we divide 865 by 342, we get 2 and a remainder of 181.
The next digit of our result is 2. 
Result so far: 2.0
If we take 684 away from 865, we end up with 181.
Fetch the next digit (8) from the dividend, attach it to 181 and continue: 1818 / 342

On to step 4:
If we divide 1818 by 342, we get 5 and a remainder of 108.
Write down 5 as next digit of the result. 
Result so far: 25.0
If we subtract 1710 from 1818, we get 108.
Grab the next digit (4) from the dividend, add it to 108, then carry on: 1084 / 342

On to step 5:
The number 342 fits into 1084 3 times, leaving a remainder of 58.
Put 3 as the next digit of the answer. 
Result so far: 253.0
Deduct 1026 from 1084 and we're left with 58.
Grab the next digit (8) from the dividend, add it to 58, then carry on: 588 / 342

Going ahead to step 6:
The number 342 fits into 588 1 times, leaving a remainder of 246.
The next digit of our result is 1. 
Result so far: 2531.0
Subtracting 342 from 588 leaves us with 246.
Fetch the next digit (9) from the dividend, attach it to 246 and continue: 2469 / 342

Step 7:
When dividing 2469 by 342, we get 7 with a remainder of 75.
Put 7 as the next digit of the answer. 
Result so far: 25317.0
Deduct 2394 from 2469 and we're left with 75.
Append the next digit (1) from the dividend to 75 and continue with: 751 / 342

Step 8:
342 goes into 751 2 times with a remainder of 67.
Write down 2 as next digit of the result. 
Result so far: 253172.0
Subtract 684 from 751 to get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Step 9:
If we divide 670 by 342, we get 1 and a remainder of 328.
Put 1 as the next digit of the answer. 
Result so far: 253172.1
If we subtract 342 from 670, we get 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Moving on to step 10:
The number 342 fits into 3280 9 times, leaving a remainder of 202.
Put 9 as the next digit of the answer. 
Result so far: 253172.19
Deduct 3078 from 3280 and we're left with 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Moving on to step 11:
If we divide 2020 by 342, we get 5 and a remainder of 310.
Write down 5 as next digit of the result. 
Result so far: 253172.195
Subtract 1710 from 2020 to get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Step 12:
342 goes into 3100 9 times with a remainder of 22.
Write down 9 as next digit of the result. 
Result so far: 253172.1959
If we subtract 3078 from 3100, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 13:
220 divided by 342 is 0 with a remainder of 220.
Put 0 as the next digit of the answer. 
Result so far: 253172.1959
If we take 0 away from 220, we end up with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Going ahead to step 14:
The number 342 fits into 2200 6 times, leaving a remainder of 148.
Record the quotient 6 as the next digit in the result. 
Result so far: 253172.195906
Subtract 2052 from 2200 to get 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

On to step 15:
The number 342 fits into 1480 4 times, leaving a remainder of 112.
The number 4 becomes the next digit in our result. 
Result so far: 253172.1959064
If we take 1368 away from 1480, we end up with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

On to step 16:
When dividing 1120 by 342, we get 3 with a remainder of 94.
Put 3 as the next digit of the answer. 
Result so far: 253172.19590643
Subtract 1026 from 1120 to get 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

In conclusion, the division gives 253172.19590643 with a balance of 9.4e-08.
