We're dividing 28103643 by 217 
Our goal is to divide 28103643 by 217.

Going ahead to step 1:
When dividing 2 by 217, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 217

Step 2:
28 divided by 217 is 0 with a remainder of 28.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 28 to get 28.
Fetch the next digit (1) from the dividend, attach it to 28 and continue: 281 / 217

Moving on to step 3:
The number 217 fits into 281 1 times, leaving a remainder of 64.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 217 from 281 to get 64.
Fetch the next digit (0) from the dividend, attach it to 64 and continue: 640 / 217

Let's proceed to step 4:
217 can be fit into 640 2 times, resulting in a remainder of 206.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we subtract 434 from 640, we get 206.
Grab the next digit (3) from the dividend, add it to 206, then carry on: 2063 / 217

On to step 5:
217 goes into 2063 9 times with a remainder of 110.
Put 9 as the next digit of the answer. 
Result so far: 129.0
Subtract 1953 from 2063 to get 110.
Append the next digit (6) from the dividend to 110 and continue with: 1106 / 217

Moving on to step 6:
1106 divided by 217 is 5 with a remainder of 21.
Record the quotient 5 as the next digit in the result. 
Result so far: 1295.0
Subtract 1085 from 1106 to get 21.
Fetch the next digit (4) from the dividend, attach it to 21 and continue: 214 / 217

On to step 7:
217 goes into 214 0 times with a remainder of 214.
Write down 0 as next digit of the result. 
Result so far: 12950.0
Subtract 0 from 214 to get 214.
Append the next digit (3) from the dividend to 214 and continue with: 2143 / 217

Step 8:
If we divide 2143 by 217, we get 9 and a remainder of 190.
Write down 9 as next digit of the result. 
Result so far: 129509.0
Subtracting 1953 from 2143 leaves us with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Going ahead to step 9:
If we divide 1900 by 217, we get 8 and a remainder of 164.
Write down 8 as next digit of the result. 
Result so far: 129509.8
Subtracting 1736 from 1900 leaves us with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

On to step 10:
217 goes into 1640 7 times with a remainder of 121.
Write down 7 as next digit of the result. 
Result so far: 129509.87
If we take 1519 away from 1640, we end up with 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Moving on to step 11:
1210 divided by 217 is 5 with a remainder of 125.
Write down 5 as next digit of the result. 
Result so far: 129509.875
Deduct 1085 from 1210 and we're left with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Let's proceed to step 12:
If we divide 1250 by 217, we get 5 and a remainder of 165.
Record the quotient 5 as the next digit in the result. 
Result so far: 129509.8755
The remainder is 165 after subtracting 1085 from 1250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

The quotient of the division is 129509.8755, and the remainder is 0.00165.
