We're dividing 42059752 by 836 
The aim is to understand the frequency of 836 in 42059752.

Step 1:
When dividing 4 by 836, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 836

Moving on to step 2:
42 divided by 836 is 0 with a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 42, we end up with 42.
Bring next digit (0) of the dividend behind the 42 and repeat the process: 420 / 836

On to step 3:
The number 836 fits into 420 0 times, leaving a remainder of 420.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 420, we end up with 420.
Grab the next digit (5) from the dividend, add it to 420, then carry on: 4205 / 836

On to step 4:
4205 divided by 836 is 5 with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we take 4180 away from 4205, we end up with 25.
Grab the next digit (9) from the dividend, add it to 25, then carry on: 259 / 836

Advancing to step 5:
When dividing 259 by 836, we get 0 with a remainder of 259.
Write down 0 as next digit of the result. 
Result so far: 50.0
Subtracting 0 from 259 leaves us with 259.
Include the next digit (7) from the dividend after 259, then repeat: 2597 / 836

On to step 6:
2597 divided by 836 is 3 with a remainder of 89.
Write down 3 as next digit of the result. 
Result so far: 503.0
If we take 2508 away from 2597, we end up with 89.
Bring next digit (5) of the dividend behind the 89 and repeat the process: 895 / 836

On to step 7:
836 can be fit into 895 1 times, resulting in a remainder of 59.
The number 1 becomes the next digit in our result. 
Result so far: 5031.0
If we take 836 away from 895, we end up with 59.
Fetch the next digit (2) from the dividend, attach it to 59 and continue: 592 / 836

Going ahead to step 8:
If we divide 592 by 836, we get 0 and a remainder of 592.
Record the quotient 0 as the next digit in the result. 
Result so far: 50310.0
The remainder is 592 after subtracting 0 from 592.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5920, and continue the process.

On to step 9:
5920 divided by 836 is 7 with a remainder of 68.
The number 7 becomes the next digit in our result. 
Result so far: 50310.7
The remainder is 68 after subtracting 5852 from 5920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 10:
When dividing 680 by 836, we get 0 with a remainder of 680.
Put 0 as the next digit of the answer. 
Result so far: 50310.7
If we take 0 away from 680, we end up with 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Step 11:
If we divide 6800 by 836, we get 8 and a remainder of 112.
The next digit of our result is 8. 
Result so far: 50310.708
Deduct 6688 from 6800 and we're left with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Moving on to step 12:
When dividing 1120 by 836, we get 1 with a remainder of 284.
Put 1 as the next digit of the answer. 
Result so far: 50310.7081
The remainder is 284 after subtracting 836 from 1120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Advancing to step 13:
836 goes into 2840 3 times with a remainder of 332.
Write down 3 as next digit of the result. 
Result so far: 50310.70813
If we subtract 2508 from 2840, we get 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

Going ahead to step 14:
3320 divided by 836 is 3 with a remainder of 812.
Record the quotient 3 as the next digit in the result. 
Result so far: 50310.708133
Subtract 2508 from 3320 to get 812.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8120, and continue the process.

The final result is 50310.708133 with a remainder of 8.12e-05.
