126404 ÷ 73 
Let's see how many times 73 fits into 126404.

Going ahead to step 1:
73 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 73

Moving on to step 2:
The number 73 fits into 12 0 times, leaving a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Grab the next digit (6) from the dividend, add it to 12, then carry on: 126 / 73

Going ahead to step 3:
When dividing 126 by 73, we get 1 with a remainder of 53.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 73 from 126 leaves us with 53.
Fetch the next digit (4) from the dividend, attach it to 53 and continue: 534 / 73

On to step 4:
73 can be fit into 534 7 times, resulting in a remainder of 23.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
Deduct 511 from 534 and we're left with 23.
Include the next digit (0) from the dividend after 23, then repeat: 230 / 73

Moving on to step 5:
If we divide 230 by 73, we get 3 and a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 173.0
If we take 219 away from 230, we end up with 11.
Bring next digit (4) of the dividend behind the 11 and repeat the process: 114 / 73

Going ahead to step 6:
73 can be fit into 114 1 times, resulting in a remainder of 41.
Use 1 as the next digit of our solution. 
Result so far: 1731.0
Deduct 73 from 114 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

On to step 7:
73 goes into 410 5 times with a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 1731.5
If we take 365 away from 410, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 8:
If we divide 450 by 73, we get 6 and a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 1731.56
If we subtract 438 from 450, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 9:
120 divided by 73 is 1 with a remainder of 47.
Use 1 as the next digit of our solution. 
Result so far: 1731.561
If we take 73 away from 120, we end up with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Going ahead to step 10:
When dividing 470 by 73, we get 6 with a remainder of 32.
Write down 6 as next digit of the result. 
Result so far: 1731.5616
Subtract 438 from 470 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 11:
The number 73 fits into 320 4 times, leaving a remainder of 28.
Put 4 as the next digit of the answer. 
Result so far: 1731.56164
If we subtract 292 from 320, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 12:
280 divided by 73 is 3 with a remainder of 61.
The next digit of our result is 3. 
Result so far: 1731.561643
Subtract 219 from 280 to get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

On to step 13:
73 goes into 610 8 times with a remainder of 26.
Use 8 as the next digit of our solution. 
Result so far: 1731.5616438
If we take 584 away from 610, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 14:
When dividing 260 by 73, we get 3 with a remainder of 41.
Use 3 as the next digit of our solution. 
Result so far: 1731.56164383
Deduct 219 from 260 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

The final outcome is 1731.56164383, with a leftover of 4.1e-08.
