Let's divide 939021 by 73
We want to figure out the number of times 939021 can be divided by 73.

On to step 1:
When dividing 9 by 73, we get 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Take the next digit (3) from the dividend and append it to 9, then repeat: 93 / 73

Let's proceed to step 2:
If we divide 93 by 73, we get 1 and a remainder of 20.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 73 away from 93, we end up with 20.
Append the next digit (9) from the dividend to 20 and continue with: 209 / 73

Let's proceed to step 3:
When dividing 209 by 73, we get 2 with a remainder of 63.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtracting 146 from 209 leaves us with 63.
Append the next digit (0) from the dividend to 63 and continue with: 630 / 73

Moving on to step 4:
630 divided by 73 is 8 with a remainder of 46.
Record the quotient 8 as the next digit in the result. 
Result so far: 128.0
The remainder is 46 after subtracting 584 from 630.
Grab the next digit (2) from the dividend, add it to 46, then carry on: 462 / 73

Moving on to step 5:
If we divide 462 by 73, we get 6 and a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 1286.0
The remainder is 24 after subtracting 438 from 462.
Bring next digit (1) of the dividend behind the 24 and repeat the process: 241 / 73

Moving on to step 6:
73 goes into 241 3 times with a remainder of 22.
The next digit of our result is 3. 
Result so far: 12863.0
If we take 219 away from 241, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 7:
73 can be fit into 220 3 times, resulting in a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 12863.3
Subtracting 219 from 220 leaves us 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.

Moving on to step 8:
73 can be fit into 10 0 times, resulting in a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 12863.3
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 9:
100 divided by 73 is 1 with a remainder of 27.
Put 1 as the next digit of the answer. 
Result so far: 12863.301
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 10:
73 goes into 270 3 times with a remainder of 51.
Put 3 as the next digit of the answer. 
Result so far: 12863.3013
Deduct 219 from 270 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 11:
If we divide 510 by 73, we get 6 and a remainder of 72.
Put 6 as the next digit of the answer. 
Result so far: 12863.30136
If we take 438 away from 510, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 12:
If we divide 720 by 73, we get 9 and a remainder of 63.
Use 9 as the next digit of our solution. 
Result so far: 12863.301369
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.

Advancing to step 13:
73 can be fit into 630 8 times, resulting in a remainder of 46.
Write down 8 as next digit of the result. 
Result so far: 12863.3013698
Subtract 584 from 630 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 14:
When dividing 460 by 73, we get 6 with a remainder of 22.
Write down 6 as next digit of the result. 
Result so far: 12863.30136986
Deduct 438 from 460 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The final result is 12863.30136986 with a remainder of 2.2e-08.
