We're dividing 521355 by 73 
We want to divide 521355 by 73.

Step 1:
73 can be fit into 5 0 times, resulting in a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 73

On to step 2:
If we divide 52 by 73, we get 0 and a remainder of 52.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 52 to get 52.
Bring next digit (1) of the dividend behind the 52 and repeat the process: 521 / 73

Going ahead to step 3:
If we divide 521 by 73, we get 7 and a remainder of 10.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Deduct 511 from 521 and we're left with 10.
Bring next digit (3) of the dividend behind the 10 and repeat the process: 103 / 73

On to step 4:
When dividing 103 by 73, we get 1 with a remainder of 30.
Put 1 as the next digit of the answer. 
Result so far: 71.0
The remainder is 30 after subtracting 73 from 103.
Grab the next digit (5) from the dividend, add it to 30, then carry on: 305 / 73

On to step 5:
73 goes into 305 4 times with a remainder of 13.
The number 4 becomes the next digit in our result. 
Result so far: 714.0
If we take 292 away from 305, we end up with 13.
Bring next digit (5) of the dividend behind the 13 and repeat the process: 135 / 73

Let's proceed to step 6:
73 goes into 135 1 times with a remainder of 62.
Put 1 as the next digit of the answer. 
Result so far: 7141.0
The remainder is 62 after subtracting 73 from 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 7:
The number 73 fits into 620 8 times, leaving a remainder of 36.
Use 8 as the next digit of our solution. 
Result so far: 7141.8
Deduct 584 from 620 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 8:
73 can be fit into 360 4 times, resulting in a remainder of 68.
Use 4 as the next digit of our solution. 
Result so far: 7141.84
If we subtract 292 from 360, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 9:
680 divided by 73 is 9 with a remainder of 23.
Put 9 as the next digit of the answer. 
Result so far: 7141.849
Subtracting 657 from 680 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 10:
230 divided by 73 is 3 with a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 7141.8493
Deduct 219 from 230 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 11:
73 goes into 110 1 times with a remainder of 37.
The next digit of our result is 1. 
Result so far: 7141.84931
Subtract 73 from 110 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 12:
370 divided by 73 is 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 7141.849315
Subtracting 365 from 370 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 13:
If we divide 50 by 73, we get 0 and a remainder of 50.
The next digit of our result is 0. 
Result so far: 7141.849315
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 14:
If we divide 500 by 73, we get 6 and a remainder of 62.
Put 6 as the next digit of the answer. 
Result so far: 7141.84931506
Deduct 438 from 500 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

In conclusion, the division gives 7141.84931506 with a balance of 6.2e-08.
