Let's divide 212139 by 73
We're looking to find how many times 73 goes into 212139.

Step 1:
The number 73 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 73

On to step 2:
The number 73 fits into 21 0 times, leaving a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Bring next digit (2) of the dividend behind the 21 and repeat the process: 212 / 73

Going ahead to step 3:
73 can be fit into 212 2 times, resulting in a remainder of 66.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 146 from 212 leaves us with 66.
Take the next digit (1) from the dividend and append it to 66, then repeat: 661 / 73

Moving on to step 4:
When dividing 661 by 73, we get 9 with a remainder of 4.
The next digit of our result is 9. 
Result so far: 29.0
If we take 657 away from 661, we end up with 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 73

Advancing to step 5:
When dividing 43 by 73, we get 0 with a remainder of 43.
The next digit of our result is 0. 
Result so far: 290.0
If we take 0 away from 43, we end up with 43.
Grab the next digit (9) from the dividend, add it to 43, then carry on: 439 / 73

Going ahead to step 6:
The number 73 fits into 439 6 times, leaving a remainder of 1.
Write down 6 as next digit of the result. 
Result so far: 2906.0
If we take 438 away from 439, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
If we divide 10 by 73, we get 0 and a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 2906.0
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
73 goes into 100 1 times with a remainder of 27.
The number 1 becomes the next digit in our result. 
Result so far: 2906.01
The remainder is 27 after subtracting 73 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 9:
If we divide 270 by 73, we get 3 and a remainder of 51.
Use 3 as the next digit of our solution. 
Result so far: 2906.013
Subtract 219 from 270 to get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Going ahead to step 10:
73 goes into 510 6 times with a remainder of 72.
The next digit of our result is 6. 
Result so far: 2906.0136
Subtract 438 from 510 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 11:
720 divided by 73 is 9 with a remainder of 63.
Write down 9 as next digit of the result. 
Result so far: 2906.01369
If we subtract 657 from 720, we get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

On to step 12:
The number 73 fits into 630 8 times, leaving a remainder of 46.
Record the quotient 8 as the next digit in the result. 
Result so far: 2906.013698
Subtracting 584 from 630 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 13:
73 goes into 460 6 times with a remainder of 22.
Use 6 as the next digit of our solution. 
Result so far: 2906.0136986
The remainder is 22 after subtracting 438 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 14:
220 divided by 73 is 3 with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 2906.01369863
If we take 219 away from 220, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

After the division, we end up with 2906.01369863 and a remainder of 1e-09.
