390502 ÷ 73 
Our goal is to divide 390502 by 73.

On to step 1:
If we divide 3 by 73, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 73

Advancing to step 2:
When dividing 39 by 73, we get 0 with a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 39 leaves us with 39.
Take the next digit (0) from the dividend and append it to 39, then repeat: 390 / 73

Going ahead to step 3:
The number 73 fits into 390 5 times, leaving a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we take 365 away from 390, we end up with 25.
Grab the next digit (5) from the dividend, add it to 25, then carry on: 255 / 73

On to step 4:
255 divided by 73 is 3 with a remainder of 36.
The next digit of our result is 3. 
Result so far: 53.0
If we take 219 away from 255, we end up with 36.
Take the next digit (0) from the dividend and append it to 36, then repeat: 360 / 73

Let's proceed to step 5:
The number 73 fits into 360 4 times, leaving a remainder of 68.
Put 4 as the next digit of the answer. 
Result so far: 534.0
If we take 292 away from 360, we end up with 68.
Fetch the next digit (2) from the dividend, attach it to 68 and continue: 682 / 73

Let's proceed to step 6:
73 goes into 682 9 times with a remainder of 25.
Write down 9 as next digit of the result. 
Result so far: 5349.0
If we subtract 657 from 682, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 7:
73 can be fit into 250 3 times, resulting in a remainder of 31.
The next digit of our result is 3. 
Result so far: 5349.3
If we subtract 219 from 250, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 8:
If we divide 310 by 73, we get 4 and a remainder of 18.
Put 4 as the next digit of the answer. 
Result so far: 5349.34
Subtract 292 from 310 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 9:
180 divided by 73 is 2 with a remainder of 34.
Use 2 as the next digit of our solution. 
Result so far: 5349.342
Subtracting 146 from 180 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 10:
If we divide 340 by 73, we get 4 and a remainder of 48.
Put 4 as the next digit of the answer. 
Result so far: 5349.3424
If we subtract 292 from 340, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 11:
73 can be fit into 480 6 times, resulting in a remainder of 42.
Write down 6 as next digit of the result. 
Result so far: 5349.34246
If we take 438 away from 480, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 12:
420 divided by 73 is 5 with a remainder of 55.
Write down 5 as next digit of the result. 
Result so far: 5349.342465
Deduct 365 from 420 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 13:
The number 73 fits into 550 7 times, leaving a remainder of 39.
The number 7 becomes the next digit in our result. 
Result so far: 5349.3424657
Deduct 511 from 550 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 14:
73 can be fit into 390 5 times, resulting in a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 5349.34246575
Subtract 365 from 390 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Our division results in 5349.34246575 with a remaining 2.5e-08.
