86703570 ÷ 344 
We want to divide 86703570 by 344.

Advancing to step 1:
When dividing 8 by 344, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
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 / 344

On to step 2:
344 goes into 86 0 times with a remainder of 86.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 86, we get 86.
Include the next digit (7) from the dividend after 86, then repeat: 867 / 344

On to step 3:
867 divided by 344 is 2 with a remainder of 179.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 688 from 867 and we're left with 179.
Append the next digit (0) from the dividend to 179 and continue with: 1790 / 344

Step 4:
If we divide 1790 by 344, we get 5 and a remainder of 70.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
Subtract 1720 from 1790 to get 70.
Append the next digit (3) from the dividend to 70 and continue with: 703 / 344

Step 5:
When dividing 703 by 344, we get 2 with a remainder of 15.
Write down 2 as next digit of the result. 
Result so far: 252.0
Subtract 688 from 703 to get 15.
Bring next digit (5) of the dividend behind the 15 and repeat the process: 155 / 344

Moving on to step 6:
344 can be fit into 155 0 times, resulting in a remainder of 155.
Put 0 as the next digit of the answer. 
Result so far: 2520.0
Subtract 0 from 155 to get 155.
Fetch the next digit (7) from the dividend, attach it to 155 and continue: 1557 / 344

On to step 7:
344 goes into 1557 4 times with a remainder of 181.
Write down 4 as next digit of the result. 
Result so far: 25204.0
The remainder is 181 after subtracting 1376 from 1557.
Include the next digit (0) from the dividend after 181, then repeat: 1810 / 344

Let's proceed to step 8:
If we divide 1810 by 344, we get 5 and a remainder of 90.
Use 5 as the next digit of our solution. 
Result so far: 252045.0
If we take 1720 away from 1810, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Let's proceed to step 9:
900 divided by 344 is 2 with a remainder of 212.
The number 2 becomes the next digit in our result. 
Result so far: 252045.2
If we take 688 away from 900, we end up with 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

On to step 10:
2120 divided by 344 is 6 with a remainder of 56.
Use 6 as the next digit of our solution. 
Result so far: 252045.26
Deduct 2064 from 2120 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 11:
344 can be fit into 560 1 times, resulting in a remainder of 216.
Put 1 as the next digit of the answer. 
Result so far: 252045.261
Subtracting 344 from 560 leaves us with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Step 12:
The number 344 fits into 2160 6 times, leaving a remainder of 96.
Put 6 as the next digit of the answer. 
Result so far: 252045.2616
Subtract 2064 from 2160 to get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Advancing to step 13:
344 goes into 960 2 times with a remainder of 272.
Record the quotient 2 as the next digit in the result. 
Result so far: 252045.26162
Deduct 688 from 960 and we're left with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Going ahead to step 14:
When dividing 2720 by 344, we get 7 with a remainder of 312.
Write down 7 as next digit of the result. 
Result so far: 252045.261627
Subtract 2408 from 2720 to get 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Step 15:
If we divide 3120 by 344, we get 9 and a remainder of 24.
The next digit of our result is 9. 
Result so far: 252045.2616279
Deduct 3096 from 3120 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 16:
240 divided by 344 is 0 with a remainder of 240.
The next digit of our result is 0. 
Result so far: 252045.2616279
The remainder is 240 after subtracting 0 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

After the division, we end up with 252045.2616279 and a remainder of 2.4e-07.
