72932350 ÷ 520 
The aim is to understand the frequency of 520 in 72932350.

Going ahead to step 1:
When dividing 7 by 520, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 520

Going ahead to step 2:
When dividing 72 by 520, we get 0 with a remainder of 72.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 72 to get 72.
Fetch the next digit (9) from the dividend, attach it to 72 and continue: 729 / 520

Advancing to step 3:
The number 520 fits into 729 1 times, leaving a remainder of 209.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 520 from 729 to get 209.
Take the next digit (3) from the dividend and append it to 209, then repeat: 2093 / 520

Going ahead to step 4:
520 can be fit into 2093 4 times, resulting in a remainder of 13.
Use 4 as the next digit of our solution. 
Result so far: 14.0
Subtracting 2080 from 2093 leaves us with 13.
Bring next digit (2) of the dividend behind the 13 and repeat the process: 132 / 520

Step 5:
The number 520 fits into 132 0 times, leaving a remainder of 132.
Use 0 as the next digit of our solution. 
Result so far: 140.0
Deduct 0 from 132 and we're left with 132.
Fetch the next digit (3) from the dividend, attach it to 132 and continue: 1323 / 520

On to step 6:
520 goes into 1323 2 times with a remainder of 283.
Use 2 as the next digit of our solution. 
Result so far: 1402.0
Subtracting 1040 from 1323 leaves us with 283.
Append the next digit (5) from the dividend to 283 and continue with: 2835 / 520

Let's proceed to step 7:
520 can be fit into 2835 5 times, resulting in a remainder of 235.
The number 5 becomes the next digit in our result. 
Result so far: 14025.0
The remainder is 235 after subtracting 2600 from 2835.
Grab the next digit (0) from the dividend, add it to 235, then carry on: 2350 / 520

Let's proceed to step 8:
520 goes into 2350 4 times with a remainder of 270.
The next digit of our result is 4. 
Result so far: 140254.0
If we subtract 2080 from 2350, we get 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

On to step 9:
520 goes into 2700 5 times with a remainder of 100.
The next digit of our result is 5. 
Result so far: 140254.5
If we take 2600 away from 2700, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 10:
The number 520 fits into 1000 1 times, leaving a remainder of 480.
Use 1 as the next digit of our solution. 
Result so far: 140254.51
Deduct 520 from 1000 and we're left with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Going ahead to step 11:
4800 divided by 520 is 9 with a remainder of 120.
Put 9 as the next digit of the answer. 
Result so far: 140254.519
Subtract 4680 from 4800 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Moving on to step 12:
1200 divided by 520 is 2 with a remainder of 160.
Record the quotient 2 as the next digit in the result. 
Result so far: 140254.5192
Subtract 1040 from 1200 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 13:
If we divide 1600 by 520, we get 3 and a remainder of 40.
Record the quotient 3 as the next digit in the result. 
Result so far: 140254.51923
If we subtract 1560 from 1600, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 14:
When dividing 400 by 520, we get 0 with a remainder of 400.
Write down 0 as next digit of the result. 
Result so far: 140254.51923
If we take 0 away from 400, we end up with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Let's proceed to step 15:
520 goes into 4000 7 times with a remainder of 360.
The next digit of our result is 7. 
Result so far: 140254.5192307
Subtracting 3640 from 4000 leaves us with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Advancing to step 16:
If we divide 3600 by 520, we get 6 and a remainder of 480.
Put 6 as the next digit of the answer. 
Result so far: 140254.51923076
If we subtract 3120 from 3600, we get 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

The quotient of the division is 140254.51923076, and the remainder is 4.8e-07.
