Let's divide 23138343 by 356
We want to figure out the number of times 23138343 can be divided by 356.

Step 1:
When dividing 2 by 356, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 356

On to step 2:
23 divided by 356 is 0 with a remainder of 23.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 23, we end up with 23.
Take the next digit (1) from the dividend and append it to 23, then repeat: 231 / 356

On to step 3:
The number 356 fits into 231 0 times, leaving a remainder of 231.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 231 after subtracting 0 from 231.
Include the next digit (3) from the dividend after 231, then repeat: 2313 / 356

Moving on to step 4:
When dividing 2313 by 356, we get 6 with a remainder of 177.
The next digit of our result is 6. 
Result so far: 6.0
Subtract 2136 from 2313 to get 177.
Grab the next digit (8) from the dividend, add it to 177, then carry on: 1778 / 356

Advancing to step 5:
The number 356 fits into 1778 4 times, leaving a remainder of 354.
Record the quotient 4 as the next digit in the result. 
Result so far: 64.0
If we take 1424 away from 1778, we end up with 354.
Bring next digit (3) of the dividend behind the 354 and repeat the process: 3543 / 356

Moving on to step 6:
3543 divided by 356 is 9 with a remainder of 339.
Write down 9 as next digit of the result. 
Result so far: 649.0
Subtracting 3204 from 3543 leaves us with 339.
Include the next digit (4) from the dividend after 339, then repeat: 3394 / 356

On to step 7:
If we divide 3394 by 356, we get 9 and a remainder of 190.
Put 9 as the next digit of the answer. 
Result so far: 6499.0
The remainder is 190 after subtracting 3204 from 3394.
Append the next digit (3) from the dividend to 190 and continue with: 1903 / 356

Step 8:
When dividing 1903 by 356, we get 5 with a remainder of 123.
Record the quotient 5 as the next digit in the result. 
Result so far: 64995.0
The remainder is 123 after subtracting 1780 from 1903.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Going ahead to step 9:
The number 356 fits into 1230 3 times, leaving a remainder of 162.
The next digit of our result is 3. 
Result so far: 64995.3
Deduct 1068 from 1230 and we're left with 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

On to step 10:
The number 356 fits into 1620 4 times, leaving a remainder of 196.
Write down 4 as next digit of the result. 
Result so far: 64995.34
If we take 1424 away from 1620, we end up with 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Moving on to step 11:
356 can be fit into 1960 5 times, resulting in a remainder of 180.
Record the quotient 5 as the next digit in the result. 
Result so far: 64995.345
If we subtract 1780 from 1960, we get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Moving on to step 12:
356 goes into 1800 5 times with a remainder of 20.
The next digit of our result is 5. 
Result so far: 64995.3455
Deduct 1780 from 1800 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 64995.3455, with a leftover of 0.0002.
