We're dividing 620688 by 73 
We're looking to find how many times 73 goes into 620688.

On to step 1:
73 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (2) from the dividend, add it to 6, then carry on: 62 / 73

Going ahead to step 2:
62 divided by 73 is 0 with a remainder of 62.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 62 leaves us with 62.
Append the next digit (0) from the dividend to 62 and continue with: 620 / 73

Moving on to step 3:
If we divide 620 by 73, we get 8 and a remainder of 36.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Deduct 584 from 620 and we're left with 36.
Grab the next digit (6) from the dividend, add it to 36, then carry on: 366 / 73

Moving on to step 4:
The number 73 fits into 366 5 times, leaving a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 85.0
If we take 365 away from 366, we end up with 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 73

On to step 5:
73 can be fit into 18 0 times, resulting in a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 850.0
The remainder is 18 after subtracting 0 from 18.
Grab the next digit (8) from the dividend, add it to 18, then carry on: 188 / 73

Advancing to step 6:
The number 73 fits into 188 2 times, leaving a remainder of 42.
The number 2 becomes the next digit in our result. 
Result so far: 8502.0
If we subtract 146 from 188, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 7:
420 divided by 73 is 5 with a remainder of 55.
Use 5 as the next digit of our solution. 
Result so far: 8502.5
The remainder is 55 after subtracting 365 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 8:
When dividing 550 by 73, we get 7 with a remainder of 39.
The next digit of our result is 7. 
Result so far: 8502.57
The remainder is 39 after subtracting 511 from 550.
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 9:
If we divide 390 by 73, we get 5 and a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 8502.575
If we take 365 away from 390, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 10:
73 goes into 250 3 times with a remainder of 31.
Use 3 as the next digit of our solution. 
Result so far: 8502.5753
Deduct 219 from 250 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 11:
73 goes into 310 4 times with a remainder of 18.
Put 4 as the next digit of the answer. 
Result so far: 8502.57534
If we subtract 292 from 310, we 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.

Step 12:
When dividing 180 by 73, we get 2 with a remainder of 34.
Put 2 as the next digit of the answer. 
Result so far: 8502.575342
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.

Advancing to step 13:
If we divide 340 by 73, we get 4 and a remainder of 48.
The next digit of our result is 4. 
Result so far: 8502.5753424
Subtract 292 from 340 to 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.

Moving on to step 14:
73 can be fit into 480 6 times, resulting in a remainder of 42.
The next digit of our result is 6. 
Result so far: 8502.57534246
Subtracting 438 from 480 leaves us 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.

In conclusion, the division gives 8502.57534246 with a balance of 4.2e-08.
