87300109 ÷ 348 
Our goal is to divide 87300109 by 348.

On to step 1:
8 divided by 348 is 0 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.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 348

Going ahead to step 2:
348 goes into 87 0 times with a remainder of 87.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 87 and we're left with 87.
Grab the next digit (3) from the dividend, add it to 87, then carry on: 873 / 348

On to step 3:
348 goes into 873 2 times with a remainder of 177.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 696 away from 873, we end up with 177.
Grab the next digit (0) from the dividend, add it to 177, then carry on: 1770 / 348

Step 4:
348 can be fit into 1770 5 times, resulting in a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
The remainder is 30 after subtracting 1740 from 1770.
Grab the next digit (0) from the dividend, add it to 30, then carry on: 300 / 348

Moving on to step 5:
The number 348 fits into 300 0 times, leaving a remainder of 300.
Put 0 as the next digit of the answer. 
Result so far: 250.0
Subtract 0 from 300 to get 300.
Append the next digit (1) from the dividend to 300 and continue with: 3001 / 348

Advancing to step 6:
When dividing 3001 by 348, we get 8 with a remainder of 217.
The number 8 becomes the next digit in our result. 
Result so far: 2508.0
Subtracting 2784 from 3001 leaves us with 217.
Grab the next digit (0) from the dividend, add it to 217, then carry on: 2170 / 348

Advancing to step 7:
348 goes into 2170 6 times with a remainder of 82.
Put 6 as the next digit of the answer. 
Result so far: 25086.0
If we take 2088 away from 2170, we end up with 82.
Grab the next digit (9) from the dividend, add it to 82, then carry on: 829 / 348

Moving on to step 8:
348 can be fit into 829 2 times, resulting in a remainder of 133.
Write down 2 as next digit of the result. 
Result so far: 250862.0
The remainder is 133 after subtracting 696 from 829.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Going ahead to step 9:
1330 divided by 348 is 3 with a remainder of 286.
Use 3 as the next digit of our solution. 
Result so far: 250862.3
Subtract 1044 from 1330 to get 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Advancing to step 10:
348 goes into 2860 8 times with a remainder of 76.
The next digit of our result is 8. 
Result so far: 250862.38
The remainder is 76 after subtracting 2784 from 2860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 11:
The number 348 fits into 760 2 times, leaving a remainder of 64.
Write down 2 as next digit of the result. 
Result so far: 250862.382
If we subtract 696 from 760, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 12:
If we divide 640 by 348, we get 1 and a remainder of 292.
Write down 1 as next digit of the result. 
Result so far: 250862.3821
If we subtract 348 from 640, we get 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Moving on to step 13:
When dividing 2920 by 348, we get 8 with a remainder of 136.
The next digit of our result is 8. 
Result so far: 250862.38218
Subtracting 2784 from 2920 leaves us with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Advancing to step 14:
348 goes into 1360 3 times with a remainder of 316.
Write down 3 as next digit of the result. 
Result so far: 250862.382183
If we subtract 1044 from 1360, we get 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

Moving on to step 15:
348 goes into 3160 9 times with a remainder of 28.
Write down 9 as next digit of the result. 
Result so far: 250862.3821839
Subtract 3132 from 3160 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 16:
348 goes into 280 0 times with a remainder of 280.
The next digit of our result is 0. 
Result so far: 250862.3821839
If we subtract 0 from 280, we get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

The quotient of the division is 250862.3821839, and the remainder is 2.8e-07.
