73391075 ÷ 523 
The aim is to understand the frequency of 523 in 73391075.

On to step 1:
523 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (3) from the dividend and append it to 7, then repeat: 73 / 523

Step 2:
When dividing 73 by 523, we get 0 with a remainder of 73.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 73 to get 73.
Grab the next digit (3) from the dividend, add it to 73, then carry on: 733 / 523

Step 3:
733 divided by 523 is 1 with a remainder of 210.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 523 from 733, we get 210.
Fetch the next digit (9) from the dividend, attach it to 210 and continue: 2109 / 523

Going ahead to step 4:
523 goes into 2109 4 times with a remainder of 17.
The next digit of our result is 4. 
Result so far: 14.0
If we subtract 2092 from 2109, we get 17.
Grab the next digit (1) from the dividend, add it to 17, then carry on: 171 / 523

Advancing to step 5:
When dividing 171 by 523, we get 0 with a remainder of 171.
The next digit of our result is 0. 
Result so far: 140.0
Subtract 0 from 171 to get 171.
Append the next digit (0) from the dividend to 171 and continue with: 1710 / 523

Let's proceed to step 6:
If we divide 1710 by 523, we get 3 and a remainder of 141.
Write down 3 as next digit of the result. 
Result so far: 1403.0
Subtracting 1569 from 1710 leaves us with 141.
Take the next digit (7) from the dividend and append it to 141, then repeat: 1417 / 523

On to step 7:
When dividing 1417 by 523, we get 2 with a remainder of 371.
Write down 2 as next digit of the result. 
Result so far: 14032.0
The remainder is 371 after subtracting 1046 from 1417.
Take the next digit (5) from the dividend and append it to 371, then repeat: 3715 / 523

Let's proceed to step 8:
3715 divided by 523 is 7 with a remainder of 54.
Record the quotient 7 as the next digit in the result. 
Result so far: 140327.0
If we take 3661 away from 3715, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 9:
540 divided by 523 is 1 with a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 140327.1
If we subtract 523 from 540, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 10:
When dividing 170 by 523, we get 0 with a remainder of 170.
Record the quotient 0 as the next digit in the result. 
Result so far: 140327.1
If we take 0 away from 170, we end up with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Let's proceed to step 11:
1700 divided by 523 is 3 with a remainder of 131.
Write down 3 as next digit of the result. 
Result so far: 140327.103
The remainder is 131 after subtracting 1569 from 1700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

On to step 12:
When dividing 1310 by 523, we get 2 with a remainder of 264.
Write down 2 as next digit of the result. 
Result so far: 140327.1032
Subtracting 1046 from 1310 leaves us with 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

On to step 13:
When dividing 2640 by 523, we get 5 with a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 140327.10325
Deduct 2615 from 2640 and we're left 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 14:
250 divided by 523 is 0 with a remainder of 250.
Write down 0 as next digit of the result. 
Result so far: 140327.10325
If we subtract 0 from 250, we get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Advancing to step 15:
523 can be fit into 2500 4 times, resulting in a remainder of 408.
Write down 4 as next digit of the result. 
Result so far: 140327.1032504
The remainder is 408 after subtracting 2092 from 2500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Advancing to step 16:
523 can be fit into 4080 7 times, resulting in a remainder of 419.
Write down 7 as next digit of the result. 
Result so far: 140327.10325047
The remainder is 419 after subtracting 3661 from 4080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4190, and continue the process.

In conclusion, the division gives 140327.10325047 with a balance of 4.19e-07.
