We look at the division of 355146 by 73 
We want to figure out the number of times 355146 can be divided by 73.

On to step 1:
The number 73 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 73

On to step 2:
35 divided by 73 is 0 with a remainder of 35.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 35, we end up with 35.
Fetch the next digit (5) from the dividend, attach it to 35 and continue: 355 / 73

Advancing to step 3:
73 can be fit into 355 4 times, resulting in a remainder of 63.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we take 292 away from 355, we end up with 63.
Append the next digit (1) from the dividend to 63 and continue with: 631 / 73

On to step 4:
The number 73 fits into 631 8 times, leaving a remainder of 47.
The number 8 becomes the next digit in our result. 
Result so far: 48.0
Deduct 584 from 631 and we're left with 47.
Take the next digit (4) from the dividend and append it to 47, then repeat: 474 / 73

On to step 5:
474 divided by 73 is 6 with a remainder of 36.
Use 6 as the next digit of our solution. 
Result so far: 486.0
The remainder is 36 after subtracting 438 from 474.
Fetch the next digit (6) from the dividend, attach it to 36 and continue: 366 / 73

Going ahead to step 6:
When dividing 366 by 73, we get 5 with a remainder of 1.
The next digit of our result is 5. 
Result so far: 4865.0
If we subtract 365 from 366, we get 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:
When dividing 10 by 73, we get 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 4865.0
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.

Moving on to step 8:
If we divide 100 by 73, we get 1 and a remainder of 27.
Put 1 as the next digit of the answer. 
Result so far: 4865.01
If we take 73 away from 100, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 9:
The number 73 fits into 270 3 times, leaving a remainder of 51.
The next digit of our result is 3. 
Result so far: 4865.013
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.

Going ahead to step 10:
73 can be fit into 510 6 times, resulting in a remainder of 72.
The next digit of our result is 6. 
Result so far: 4865.0136
Deduct 438 from 510 and we're left 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.

Moving on to step 11:
73 can be fit into 720 9 times, resulting in a remainder of 63.
The number 9 becomes the next digit in our result. 
Result so far: 4865.01369
The remainder is 63 after subtracting 657 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Let's proceed to step 12:
630 divided by 73 is 8 with a remainder of 46.
Use 8 as the next digit of our solution. 
Result so far: 4865.013698
Deduct 584 from 630 and we're left 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.

Going ahead to step 13:
460 divided by 73 is 6 with a remainder of 22.
Write down 6 as next digit of the result. 
Result so far: 4865.0136986
If we take 438 away from 460, 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.

Let's proceed to step 14:
If we divide 220 by 73, we get 3 and a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 4865.01369863
Subtract 219 from 220 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The final outcome is 4865.01369863, with a leftover of 1e-09.
