87024510 ÷ 343 
We want to divide 87024510 by 343.

Moving on to step 1:
When dividing 8 by 343, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 343

Moving on to step 2:
343 can be fit into 87 0 times, resulting in 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 (0) from the dividend, add it to 87, then carry on: 870 / 343

Step 3:
870 divided by 343 is 2 with a remainder of 184.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 686 from 870 leaves us with 184.
Take the next digit (2) from the dividend and append it to 184, then repeat: 1842 / 343

Step 4:
If we divide 1842 by 343, we get 5 and a remainder of 127.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
If we subtract 1715 from 1842, we get 127.
Bring next digit (4) of the dividend behind the 127 and repeat the process: 1274 / 343

Going ahead to step 5:
The number 343 fits into 1274 3 times, leaving a remainder of 245.
The number 3 becomes the next digit in our result. 
Result so far: 253.0
If we subtract 1029 from 1274, we get 245.
Append the next digit (5) from the dividend to 245 and continue with: 2455 / 343

Step 6:
When dividing 2455 by 343, we get 7 with a remainder of 54.
Use 7 as the next digit of our solution. 
Result so far: 2537.0
Subtracting 2401 from 2455 leaves us with 54.
Append the next digit (1) from the dividend to 54 and continue with: 541 / 343

On to step 7:
The number 343 fits into 541 1 times, leaving a remainder of 198.
Record the quotient 1 as the next digit in the result. 
Result so far: 25371.0
If we subtract 343 from 541, we get 198.
Fetch the next digit (0) from the dividend, attach it to 198 and continue: 1980 / 343

Step 8:
1980 divided by 343 is 5 with a remainder of 265.
Use 5 as the next digit of our solution. 
Result so far: 253715.0
If we take 1715 away from 1980, we end up with 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

On to step 9:
If we divide 2650 by 343, we get 7 and a remainder of 249.
Use 7 as the next digit of our solution. 
Result so far: 253715.7
If we take 2401 away from 2650, we end up with 249.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2490, and continue the process.

On to step 10:
The number 343 fits into 2490 7 times, leaving a remainder of 89.
Put 7 as the next digit of the answer. 
Result so far: 253715.77
Deduct 2401 from 2490 and we're left with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

After the division, we end up with 253715.77 and a remainder of 0.089.
