We're dividing 213236 by 73 
We want to figure out the number of times 213236 can be divided by 73.

On to step 1:
73 can be fit into 2 0 times, resulting in a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 73

Going ahead to step 2:
If we divide 21 by 73, we get 0 and a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Grab the next digit (3) from the dividend, add it to 21, then carry on: 213 / 73

On to step 3:
73 goes into 213 2 times with a remainder of 67.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 146 from 213, we get 67.
Append the next digit (2) from the dividend to 67 and continue with: 672 / 73

Advancing to step 4:
If we divide 672 by 73, we get 9 and a remainder of 15.
Write down 9 as next digit of the result. 
Result so far: 29.0
Subtract 657 from 672 to get 15.
Bring next digit (3) of the dividend behind the 15 and repeat the process: 153 / 73

On to step 5:
The number 73 fits into 153 2 times, leaving a remainder of 7.
The number 2 becomes the next digit in our result. 
Result so far: 292.0
The remainder is 7 after subtracting 146 from 153.
Include the next digit (6) from the dividend after 7, then repeat: 76 / 73

Going ahead to step 6:
73 goes into 76 1 times with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 2921.0
Deduct 73 from 76 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 7:
73 can be fit into 30 0 times, resulting in a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 2921.0
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 8:
When dividing 300 by 73, we get 4 with a remainder of 8.
The next digit of our result is 4. 
Result so far: 2921.04
Subtracting 292 from 300 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 9:
The number 73 fits into 80 1 times, leaving a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 2921.041
Subtract 73 from 80 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 10:
70 divided by 73 is 0 with a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 2921.041
Subtract 0 from 70 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 11:
73 can be fit into 700 9 times, resulting in a remainder of 43.
Record the quotient 9 as the next digit in the result. 
Result so far: 2921.04109
Subtracting 657 from 700 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Going ahead to step 12:
73 goes into 430 5 times with a remainder of 65.
Record the quotient 5 as the next digit in the result. 
Result so far: 2921.041095
If we take 365 away from 430, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

On to step 13:
73 can be fit into 650 8 times, resulting in a remainder of 66.
Write down 8 as next digit of the result. 
Result so far: 2921.0410958
Subtracting 584 from 650 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 14:
660 divided by 73 is 9 with a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 2921.04109589
Subtract 657 from 660 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

The final result is 2921.04109589 with a remainder of 3e-09.
