We divide 91208164 by 217
Let's see how many times 217 fits into 91208164.

On to step 1:
217 can be fit into 9 0 times, resulting in a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 217

On to step 2:
If we divide 91 by 217, we get 0 and a remainder of 91.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 91 and we're left with 91.
Grab the next digit (2) from the dividend, add it to 91, then carry on: 912 / 217

Going ahead to step 3:
If we divide 912 by 217, we get 4 and a remainder of 44.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 868 from 912 leaves us with 44.
Grab the next digit (0) from the dividend, add it to 44, then carry on: 440 / 217

Going ahead to step 4:
The number 217 fits into 440 2 times, leaving a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 42.0
The remainder is 6 after subtracting 434 from 440.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 217

Let's proceed to step 5:
The number 217 fits into 68 0 times, leaving a remainder of 68.
Record the quotient 0 as the next digit in the result. 
Result so far: 420.0
Subtract 0 from 68 to get 68.
Grab the next digit (1) from the dividend, add it to 68, then carry on: 681 / 217

Going ahead to step 6:
When dividing 681 by 217, we get 3 with a remainder of 30.
Put 3 as the next digit of the answer. 
Result so far: 4203.0
The remainder is 30 after subtracting 651 from 681.
Bring next digit (6) of the dividend behind the 30 and repeat the process: 306 / 217

Step 7:
The number 217 fits into 306 1 times, leaving a remainder of 89.
Use 1 as the next digit of our solution. 
Result so far: 42031.0
If we subtract 217 from 306, we get 89.
Fetch the next digit (4) from the dividend, attach it to 89 and continue: 894 / 217

Let's proceed to step 8:
When dividing 894 by 217, we get 4 with a remainder of 26.
Put 4 as the next digit of the answer. 
Result so far: 420314.0
Subtract 868 from 894 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 9:
217 goes into 260 1 times with a remainder of 43.
Put 1 as the next digit of the answer. 
Result so far: 420314.1
The remainder is 43 after subtracting 217 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 10:
If we divide 430 by 217, we get 1 and a remainder of 213.
The next digit of our result is 1. 
Result so far: 420314.11
Deduct 217 from 430 and we're left with 213.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2130, and continue the process.

The final outcome is 420314.11, with a leftover of 0.213.
