We're dividing 73424362 by 520 
The aim is to understand the frequency of 520 in 73424362.

On to step 1:
If we divide 7 by 520, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (3) from the dividend, add it to 7, then carry on: 73 / 520

Let's proceed to step 2:
When dividing 73 by 520, we get 0 with a remainder of 73.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 73 and we're left with 73.
Take the next digit (4) from the dividend and append it to 73, then repeat: 734 / 520

Advancing to step 3:
The number 520 fits into 734 1 times, leaving a remainder of 214.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 520 from 734, we get 214.
Include the next digit (2) from the dividend after 214, then repeat: 2142 / 520

Let's proceed to step 4:
2142 divided by 520 is 4 with a remainder of 62.
Put 4 as the next digit of the answer. 
Result so far: 14.0
Subtracting 2080 from 2142 leaves us with 62.
Take the next digit (4) from the dividend and append it to 62, then repeat: 624 / 520

Let's proceed to step 5:
If we divide 624 by 520, we get 1 and a remainder of 104.
The number 1 becomes the next digit in our result. 
Result so far: 141.0
Subtract 520 from 624 to get 104.
Take the next digit (3) from the dividend and append it to 104, then repeat: 1043 / 520

Advancing to step 6:
If we divide 1043 by 520, we get 2 and a remainder of 3.
Put 2 as the next digit of the answer. 
Result so far: 1412.0
If we subtract 1040 from 1043, we get 3.
Include the next digit (6) from the dividend after 3, then repeat: 36 / 520

On to step 7:
When dividing 36 by 520, we get 0 with a remainder of 36.
Record the quotient 0 as the next digit in the result. 
Result so far: 14120.0
Deduct 0 from 36 and we're left with 36.
Take the next digit (2) from the dividend and append it to 36, then repeat: 362 / 520

Step 8:
520 goes into 362 0 times with a remainder of 362.
The next digit of our result is 0. 
Result so far: 141200.0
If we subtract 0 from 362, we get 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

Advancing to step 9:
520 goes into 3620 6 times with a remainder of 500.
The next digit of our result is 6. 
Result so far: 141200.6
Subtract 3120 from 3620 to get 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Going ahead to step 10:
When dividing 5000 by 520, we get 9 with a remainder of 320.
Use 9 as the next digit of our solution. 
Result so far: 141200.69
If we subtract 4680 from 5000, we get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Advancing to step 11:
520 can be fit into 3200 6 times, resulting in a remainder of 80.
The next digit of our result is 6. 
Result so far: 141200.696
If we subtract 3120 from 3200, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 12:
If we divide 800 by 520, we get 1 and a remainder of 280.
Put 1 as the next digit of the answer. 
Result so far: 141200.6961
The remainder is 280 after subtracting 520 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Moving on to step 13:
If we divide 2800 by 520, we get 5 and a remainder of 200.
Use 5 as the next digit of our solution. 
Result so far: 141200.69615
Deduct 2600 from 2800 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Going ahead to step 14:
The number 520 fits into 2000 3 times, leaving a remainder of 440.
Use 3 as the next digit of our solution. 
Result so far: 141200.696153
If we subtract 1560 from 2000, we get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Going ahead to step 15:
520 goes into 4400 8 times with a remainder of 240.
Write down 8 as next digit of the result. 
Result so far: 141200.6961538
Deduct 4160 from 4400 and we're left with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Step 16:
2400 divided by 520 is 4 with a remainder of 320.
Write down 4 as next digit of the result. 
Result so far: 141200.69615384
The remainder is 320 after subtracting 2080 from 2400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

The quotient of the division is 141200.69615384, and the remainder is 3.2e-07.
