Let's divide 86531646 by 345
We're looking to find how many times 345 goes into 86531646.

On to step 1:
The number 345 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 345

Step 2:
If we divide 86 by 345, we get 0 and a remainder of 86.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 86 to get 86.
Take the next digit (5) from the dividend and append it to 86, then repeat: 865 / 345

On to step 3:
345 can be fit into 865 2 times, resulting in a remainder of 175.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 175 after subtracting 690 from 865.
Include the next digit (3) from the dividend after 175, then repeat: 1753 / 345

Advancing to step 4:
345 goes into 1753 5 times with a remainder of 28.
Write down 5 as next digit of the result. 
Result so far: 25.0
Subtracting 1725 from 1753 leaves us with 28.
Bring next digit (1) of the dividend behind the 28 and repeat the process: 281 / 345

On to step 5:
345 goes into 281 0 times with a remainder of 281.
The number 0 becomes the next digit in our result. 
Result so far: 250.0
Subtracting 0 from 281 leaves us with 281.
Bring next digit (6) of the dividend behind the 281 and repeat the process: 2816 / 345

Advancing to step 6:
When dividing 2816 by 345, we get 8 with a remainder of 56.
Use 8 as the next digit of our solution. 
Result so far: 2508.0
If we take 2760 away from 2816, we end up with 56.
Include the next digit (4) from the dividend after 56, then repeat: 564 / 345

Moving on to step 7:
564 divided by 345 is 1 with a remainder of 219.
Use 1 as the next digit of our solution. 
Result so far: 25081.0
If we subtract 345 from 564, we get 219.
Take the next digit (6) from the dividend and append it to 219, then repeat: 2196 / 345

Advancing to step 8:
When dividing 2196 by 345, we get 6 with a remainder of 126.
The number 6 becomes the next digit in our result. 
Result so far: 250816.0
Subtracting 2070 from 2196 leaves us with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Step 9:
If we divide 1260 by 345, we get 3 and a remainder of 225.
Record the quotient 3 as the next digit in the result. 
Result so far: 250816.3
The remainder is 225 after subtracting 1035 from 1260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Going ahead to step 10:
The number 345 fits into 2250 6 times, leaving a remainder of 180.
Use 6 as the next digit of our solution. 
Result so far: 250816.36
The remainder is 180 after subtracting 2070 from 2250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Let's proceed to step 11:
If we divide 1800 by 345, we get 5 and a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 250816.365
Deduct 1725 from 1800 and we're left with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 12:
750 divided by 345 is 2 with a remainder of 60.
Write down 2 as next digit of the result. 
Result so far: 250816.3652
If we take 690 away from 750, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 13:
345 goes into 600 1 times with a remainder of 255.
Use 1 as the next digit of our solution. 
Result so far: 250816.36521
Subtracting 345 from 600 leaves us with 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Advancing to step 14:
The number 345 fits into 2550 7 times, leaving a remainder of 135.
Write down 7 as next digit of the result. 
Result so far: 250816.365217
If we take 2415 away from 2550, we end up with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Going ahead to step 15:
If we divide 1350 by 345, we get 3 and a remainder of 315.
Record the quotient 3 as the next digit in the result. 
Result so far: 250816.3652173
If we take 1035 away from 1350, we end up with 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

Advancing to step 16:
If we divide 3150 by 345, we get 9 and a remainder of 45.
Use 9 as the next digit of our solution. 
Result so far: 250816.36521739
Deduct 3105 from 3150 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Our division results in 250816.36521739 with a remaining 4.5e-08.
