83563140 ÷ 215 
Our goal is to divide 83563140 by 215.

Advancing to step 1:
When dividing 8 by 215, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 215

Moving on to step 2:
If we divide 83 by 215, we get 0 and a remainder of 83.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 83, we get 83.
Fetch the next digit (5) from the dividend, attach it to 83 and continue: 835 / 215

On to step 3:
835 divided by 215 is 3 with a remainder of 190.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 645 from 835 and we're left with 190.
Take the next digit (6) from the dividend and append it to 190, then repeat: 1906 / 215

Moving on to step 4:
The number 215 fits into 1906 8 times, leaving a remainder of 186.
The number 8 becomes the next digit in our result. 
Result so far: 38.0
Subtracting 1720 from 1906 leaves us with 186.
Fetch the next digit (3) from the dividend, attach it to 186 and continue: 1863 / 215

Let's proceed to step 5:
If we divide 1863 by 215, we get 8 and a remainder of 143.
The next digit of our result is 8. 
Result so far: 388.0
Deduct 1720 from 1863 and we're left with 143.
Append the next digit (1) from the dividend to 143 and continue with: 1431 / 215

Moving on to step 6:
215 goes into 1431 6 times with a remainder of 141.
Use 6 as the next digit of our solution. 
Result so far: 3886.0
Subtracting 1290 from 1431 leaves us with 141.
Fetch the next digit (4) from the dividend, attach it to 141 and continue: 1414 / 215

Let's proceed to step 7:
If we divide 1414 by 215, we get 6 and a remainder of 124.
Put 6 as the next digit of the answer. 
Result so far: 38866.0
Subtracting 1290 from 1414 leaves us with 124.
Include the next digit (0) from the dividend after 124, then repeat: 1240 / 215

Moving on to step 8:
When dividing 1240 by 215, we get 5 with a remainder of 165.
Record the quotient 5 as the next digit in the result. 
Result so far: 388665.0
If we take 1075 away from 1240, we end up with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Moving on to step 9:
215 goes into 1650 7 times with a remainder of 145.
The next digit of our result is 7. 
Result so far: 388665.7
The remainder is 145 after subtracting 1505 from 1650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

On to step 10:
1450 divided by 215 is 6 with a remainder of 160.
Write down 6 as next digit of the result. 
Result so far: 388665.76
The remainder is 160 after subtracting 1290 from 1450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 11:
215 can be fit into 1600 7 times, resulting in a remainder of 95.
The number 7 becomes the next digit in our result. 
Result so far: 388665.767
Subtract 1505 from 1600 to get 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

On to step 12:
If we divide 950 by 215, we get 4 and a remainder of 90.
Record the quotient 4 as the next digit in the result. 
Result so far: 388665.7674
Subtract 860 from 950 to get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

On to step 13:
900 divided by 215 is 4 with a remainder of 40.
The next digit of our result is 4. 
Result so far: 388665.76744
If we subtract 860 from 900, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final outcome is 388665.76744, with a leftover of 4e-05.
