9525087 divided by 836 
The aim is to understand the frequency of 836 in 9525087.

Advancing to step 1:
836 goes into 9 0 times with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Bring next digit (5) of the dividend behind the 9 and repeat the process: 95 / 836

Let's proceed to step 2:
95 divided by 836 is 0 with a remainder of 95.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 95 leaves us with 95.
Take the next digit (2) from the dividend and append it to 95, then repeat: 952 / 836

Let's proceed to step 3:
When dividing 952 by 836, we get 1 with a remainder of 116.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 836 away from 952, we end up with 116.
Take the next digit (5) from the dividend and append it to 116, then repeat: 1165 / 836

Moving on to step 4:
If we divide 1165 by 836, we get 1 and a remainder of 329.
Use 1 as the next digit of our solution. 
Result so far: 11.0
If we subtract 836 from 1165, we get 329.
Bring next digit (0) of the dividend behind the 329 and repeat the process: 3290 / 836

Advancing to step 5:
If we divide 3290 by 836, we get 3 and a remainder of 782.
The next digit of our result is 3. 
Result so far: 113.0
Subtract 2508 from 3290 to get 782.
Grab the next digit (8) from the dividend, add it to 782, then carry on: 7828 / 836

Let's proceed to step 6:
836 goes into 7828 9 times with a remainder of 304.
The next digit of our result is 9. 
Result so far: 1139.0
If we take 7524 away from 7828, we end up with 304.
Take the next digit (7) from the dividend and append it to 304, then repeat: 3047 / 836

Going ahead to step 7:
836 can be fit into 3047 3 times, resulting in a remainder of 539.
The next digit of our result is 3. 
Result so far: 11393.0
If we take 2508 away from 3047, we end up with 539.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5390, and continue the process.

Step 8:
If we divide 5390 by 836, we get 6 and a remainder of 374.
Write down 6 as next digit of the result. 
Result so far: 11393.6
Subtracting 5016 from 5390 leaves us with 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

On to step 9:
If we divide 3740 by 836, we get 4 and a remainder of 396.
Record the quotient 4 as the next digit in the result. 
Result so far: 11393.64
The remainder is 396 after subtracting 3344 from 3740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Moving on to step 10:
The number 836 fits into 3960 4 times, leaving a remainder of 616.
Put 4 as the next digit of the answer. 
Result so far: 11393.644
The remainder is 616 after subtracting 3344 from 3960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6160, and continue the process.

The quotient of the division is 11393.644, and the remainder is 0.0616.
