We're dividing 400578 by 73 
Our goal is to divide 400578 by 73.

Going ahead to step 1:
The number 73 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 73

Moving on to step 2:
73 goes into 40 0 times with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 40 to get 40.
Grab the next digit (0) from the dividend, add it to 40, then carry on: 400 / 73

Step 3:
The number 73 fits into 400 5 times, leaving a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we subtract 365 from 400, we get 35.
Bring next digit (5) of the dividend behind the 35 and repeat the process: 355 / 73

Going ahead to step 4:
If we divide 355 by 73, we get 4 and a remainder of 63.
Use 4 as the next digit of our solution. 
Result so far: 54.0
The remainder is 63 after subtracting 292 from 355.
Grab the next digit (7) from the dividend, add it to 63, then carry on: 637 / 73

Going ahead to step 5:
73 goes into 637 8 times with a remainder of 53.
The number 8 becomes the next digit in our result. 
Result so far: 548.0
If we take 584 away from 637, we end up with 53.
Append the next digit (8) from the dividend to 53 and continue with: 538 / 73

Step 6:
The number 73 fits into 538 7 times, leaving a remainder of 27.
Use 7 as the next digit of our solution. 
Result so far: 5487.0
Deduct 511 from 538 and we're left 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.

Going ahead to step 7:
73 goes into 270 3 times with a remainder of 51.
The next digit of our result is 3. 
Result so far: 5487.3
If we take 219 away from 270, we end up 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.

Advancing to step 8:
73 can be fit into 510 6 times, resulting in a remainder of 72.
Write down 6 as next digit of the result. 
Result so far: 5487.36
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.

Let's proceed to step 9:
When dividing 720 by 73, we get 9 with a remainder of 63.
Record the quotient 9 as the next digit in the result. 
Result so far: 5487.369
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.

Moving on to step 10:
73 can be fit into 630 8 times, resulting in a remainder of 46.
Use 8 as the next digit of our solution. 
Result so far: 5487.3698
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.

On to step 11:
The number 73 fits into 460 6 times, leaving a remainder of 22.
The number 6 becomes the next digit in our result. 
Result so far: 5487.36986
If we subtract 438 from 460, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 12:
The number 73 fits into 220 3 times, leaving a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 5487.369863
Deduct 219 from 220 and we're left 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.

Step 13:
73 can be fit into 10 0 times, resulting in a remainder of 10.
The next digit of our result is 0. 
Result so far: 5487.369863
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 14:
The number 73 fits into 100 1 times, leaving a remainder of 27.
Record the quotient 1 as the next digit in the result. 
Result so far: 5487.36986301
If we subtract 73 from 100, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

In conclusion, the division gives 5487.36986301 with a balance of 2.7e-08.
