We're dividing 73138573 by 217 
We want to figure out the number of times 73138573 can be divided by 217.

On to step 1:
217 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (3) from the dividend, attach it to 7 and continue: 73 / 217

On to step 2:
217 goes into 73 0 times with a remainder of 73.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 73 after subtracting 0 from 73.
Bring next digit (1) of the dividend behind the 73 and repeat the process: 731 / 217

On to step 3:
When dividing 731 by 217, we get 3 with a remainder of 80.
The next digit of our result is 3. 
Result so far: 3.0
If we take 651 away from 731, we end up with 80.
Append the next digit (3) from the dividend to 80 and continue with: 803 / 217

Going ahead to step 4:
217 can be fit into 803 3 times, resulting in a remainder of 152.
Put 3 as the next digit of the answer. 
Result so far: 33.0
Subtracting 651 from 803 leaves us with 152.
Take the next digit (8) from the dividend and append it to 152, then repeat: 1528 / 217

Step 5:
If we divide 1528 by 217, we get 7 and a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 337.0
Subtracting 1519 from 1528 leaves us with 9.
Fetch the next digit (5) from the dividend, attach it to 9 and continue: 95 / 217

Going ahead to step 6:
217 goes into 95 0 times with a remainder of 95.
Put 0 as the next digit of the answer. 
Result so far: 3370.0
If we subtract 0 from 95, we get 95.
Take the next digit (7) from the dividend and append it to 95, then repeat: 957 / 217

Advancing to step 7:
957 divided by 217 is 4 with a remainder of 89.
Write down 4 as next digit of the result. 
Result so far: 33704.0
The remainder is 89 after subtracting 868 from 957.
Append the next digit (3) from the dividend to 89 and continue with: 893 / 217

Step 8:
893 divided by 217 is 4 with a remainder of 25.
Write down 4 as next digit of the result. 
Result so far: 337044.0
The remainder is 25 after subtracting 868 from 893.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 9:
If we divide 250 by 217, we get 1 and a remainder of 33.
Use 1 as the next digit of our solution. 
Result so far: 337044.1
Deduct 217 from 250 and we're left 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.

On to step 10:
330 divided by 217 is 1 with a remainder of 113.
Use 1 as the next digit of our solution. 
Result so far: 337044.11
The remainder is 113 after subtracting 217 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

After the division, we end up with 337044.11 and a remainder of 0.113.
