84126793 divided by 526 
The aim is to understand the frequency of 526 in 84126793.

Advancing to step 1:
The number 526 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 526

Step 2:
When dividing 84 by 526, we get 0 with a remainder of 84.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 84 after subtracting 0 from 84.
Include the next digit (1) from the dividend after 84, then repeat: 841 / 526

Advancing to step 3:
526 goes into 841 1 times with a remainder of 315.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 526 from 841 leaves us with 315.
Fetch the next digit (2) from the dividend, attach it to 315 and continue: 3152 / 526

Let's proceed to step 4:
If we divide 3152 by 526, we get 5 and a remainder of 522.
Write down 5 as next digit of the result. 
Result so far: 15.0
Deduct 2630 from 3152 and we're left with 522.
Fetch the next digit (6) from the dividend, attach it to 522 and continue: 5226 / 526

Step 5:
If we divide 5226 by 526, we get 9 and a remainder of 492.
Put 9 as the next digit of the answer. 
Result so far: 159.0
If we subtract 4734 from 5226, we get 492.
Fetch the next digit (7) from the dividend, attach it to 492 and continue: 4927 / 526

On to step 6:
If we divide 4927 by 526, we get 9 and a remainder of 193.
Put 9 as the next digit of the answer. 
Result so far: 1599.0
The remainder is 193 after subtracting 4734 from 4927.
Take the next digit (9) from the dividend and append it to 193, then repeat: 1939 / 526

Advancing to step 7:
When dividing 1939 by 526, we get 3 with a remainder of 361.
Use 3 as the next digit of our solution. 
Result so far: 15993.0
The remainder is 361 after subtracting 1578 from 1939.
Append the next digit (3) from the dividend to 361 and continue with: 3613 / 526

On to step 8:
526 can be fit into 3613 6 times, resulting in a remainder of 457.
Use 6 as the next digit of our solution. 
Result so far: 159936.0
If we take 3156 away from 3613, we end up with 457.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4570, and continue the process.

Advancing to step 9:
If we divide 4570 by 526, we get 8 and a remainder of 362.
Put 8 as the next digit of the answer. 
Result so far: 159936.8
If we take 4208 away from 4570, we end up with 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

Step 10:
The number 526 fits into 3620 6 times, leaving a remainder of 464.
The number 6 becomes the next digit in our result. 
Result so far: 159936.86
If we subtract 3156 from 3620, we get 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Step 11:
The number 526 fits into 4640 8 times, leaving a remainder of 432.
Put 8 as the next digit of the answer. 
Result so far: 159936.868
The remainder is 432 after subtracting 4208 from 4640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Going ahead to step 12:
4320 divided by 526 is 8 with a remainder of 112.
The number 8 becomes the next digit in our result. 
Result so far: 159936.8688
Subtract 4208 from 4320 to get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

The final result is 159936.8688 with a remainder of 0.00112.
