We look at the division of 90400868 by 217 
Our goal is to divide 90400868 by 217.

Going ahead to step 1:
The number 217 fits into 9 0 times, leaving a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 217

Step 2:
If we divide 90 by 217, we get 0 and a remainder of 90.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 90 to get 90.
Include the next digit (4) from the dividend after 90, then repeat: 904 / 217

Going ahead to step 3:
When dividing 904 by 217, we get 4 with a remainder of 36.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 868 from 904 to get 36.
Include the next digit (0) from the dividend after 36, then repeat: 360 / 217

Advancing to step 4:
If we divide 360 by 217, we get 1 and a remainder of 143.
Use 1 as the next digit of our solution. 
Result so far: 41.0
The remainder is 143 after subtracting 217 from 360.
Append the next digit (0) from the dividend to 143 and continue with: 1430 / 217

Moving on to step 5:
The number 217 fits into 1430 6 times, leaving a remainder of 128.
The number 6 becomes the next digit in our result. 
Result so far: 416.0
If we subtract 1302 from 1430, we get 128.
Include the next digit (8) from the dividend after 128, then repeat: 1288 / 217

Let's proceed to step 6:
The number 217 fits into 1288 5 times, leaving a remainder of 203.
Put 5 as the next digit of the answer. 
Result so far: 4165.0
The remainder is 203 after subtracting 1085 from 1288.
Grab the next digit (6) from the dividend, add it to 203, then carry on: 2036 / 217

Step 7:
The number 217 fits into 2036 9 times, leaving a remainder of 83.
Record the quotient 9 as the next digit in the result. 
Result so far: 41659.0
The remainder is 83 after subtracting 1953 from 2036.
Take the next digit (8) from the dividend and append it to 83, then repeat: 838 / 217

On to step 8:
838 divided by 217 is 3 with a remainder of 187.
Write down 3 as next digit of the result. 
Result so far: 416593.0
Subtracting 651 from 838 leaves us with 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

Advancing to step 9:
When dividing 1870 by 217, we get 8 with a remainder of 134.
Record the quotient 8 as the next digit in the result. 
Result so far: 416593.8
Subtracting 1736 from 1870 leaves us with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

On to step 10:
The number 217 fits into 1340 6 times, leaving a remainder of 38.
Write down 6 as next digit of the result. 
Result so far: 416593.86
The remainder is 38 after subtracting 1302 from 1340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 11:
The number 217 fits into 380 1 times, leaving a remainder of 163.
The next digit of our result is 1. 
Result so far: 416593.861
If we take 217 away from 380, we end up with 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

Advancing to step 12:
217 can be fit into 1630 7 times, resulting in a remainder of 111.
Put 7 as the next digit of the answer. 
Result so far: 416593.8617
If we take 1519 away from 1630, we end up with 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Going ahead to step 13:
217 can be fit into 1110 5 times, resulting in a remainder of 25.
The next digit of our result is 5. 
Result so far: 416593.86175
If we subtract 1085 from 1110, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 14:
If we divide 250 by 217, we get 1 and a remainder of 33.
Write down 1 as next digit of the result. 
Result so far: 416593.861751
Subtracting 217 from 250 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 15:
When dividing 330 by 217, we get 1 with a remainder of 113.
Use 1 as the next digit of our solution. 
Result so far: 416593.8617511
Deduct 217 from 330 and we're left with 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Our division results in 416593.8617511 with a remaining 1.13e-06.
