80901200 ÷ 596 
The aim is to understand the frequency of 596 in 80901200.

Let's proceed to step 1:
When dividing 8 by 596, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 596

On to step 2:
80 divided by 596 is 0 with a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 80 after subtracting 0 from 80.
Grab the next digit (9) from the dividend, add it to 80, then carry on: 809 / 596

Step 3:
When dividing 809 by 596, we get 1 with a remainder of 213.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 213 after subtracting 596 from 809.
Bring next digit (0) of the dividend behind the 213 and repeat the process: 2130 / 596

Step 4:
The number 596 fits into 2130 3 times, leaving a remainder of 342.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Subtracting 1788 from 2130 leaves us with 342.
Bring next digit (1) of the dividend behind the 342 and repeat the process: 3421 / 596

Step 5:
The number 596 fits into 3421 5 times, leaving a remainder of 441.
Record the quotient 5 as the next digit in the result. 
Result so far: 135.0
The remainder is 441 after subtracting 2980 from 3421.
Bring next digit (2) of the dividend behind the 441 and repeat the process: 4412 / 596

Step 6:
When dividing 4412 by 596, we get 7 with a remainder of 240.
Use 7 as the next digit of our solution. 
Result so far: 1357.0
If we take 4172 away from 4412, we end up with 240.
Bring next digit (0) of the dividend behind the 240 and repeat the process: 2400 / 596

Going ahead to step 7:
596 goes into 2400 4 times with a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 13574.0
If we subtract 2384 from 2400, we get 16.
Include the next digit (0) from the dividend after 16, then repeat: 160 / 596

Moving on to step 8:
When dividing 160 by 596, we get 0 with a remainder of 160.
Write down 0 as next digit of the result. 
Result so far: 135740.0
The remainder is 160 after subtracting 0 from 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 9:
The number 596 fits into 1600 2 times, leaving a remainder of 408.
Put 2 as the next digit of the answer. 
Result so far: 135740.2
If we subtract 1192 from 1600, we get 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Going ahead to step 10:
596 can be fit into 4080 6 times, resulting in a remainder of 504.
The number 6 becomes the next digit in our result. 
Result so far: 135740.26
If we subtract 3576 from 4080, we get 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

Going ahead to step 11:
The number 596 fits into 5040 8 times, leaving a remainder of 272.
Record the quotient 8 as the next digit in the result. 
Result so far: 135740.268
If we take 4768 away from 5040, we end up with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Step 12:
The number 596 fits into 2720 4 times, leaving a remainder of 336.
The number 4 becomes the next digit in our result. 
Result so far: 135740.2684
The remainder is 336 after subtracting 2384 from 2720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Step 13:
3360 divided by 596 is 5 with a remainder of 380.
Put 5 as the next digit of the answer. 
Result so far: 135740.26845
If we take 2980 away from 3360, we end up with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

On to step 14:
596 can be fit into 3800 6 times, resulting in a remainder of 224.
Use 6 as the next digit of our solution. 
Result so far: 135740.268456
If we take 3576 away from 3800, we end up with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Let's proceed to step 15:
When dividing 2240 by 596, we get 3 with a remainder of 452.
The number 3 becomes the next digit in our result. 
Result so far: 135740.2684563
If we take 1788 away from 2240, we end up with 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

Advancing to step 16:
596 goes into 4520 7 times with a remainder of 348.
The number 7 becomes the next digit in our result. 
Result so far: 135740.26845637
If we take 4172 away from 4520, we end up with 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

The final result is 135740.26845637 with a remainder of 3.48e-07.
