86794334 divided by 531 
The aim is to understand the frequency of 531 in 86794334.

Going ahead to step 1:
8 divided by 531 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 531

Moving on to step 2:
531 can be fit into 86 0 times, resulting in a remainder of 86.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 86 leaves us with 86.
Append the next digit (7) from the dividend to 86 and continue with: 867 / 531

Step 3:
If we divide 867 by 531, we get 1 and a remainder of 336.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 531 from 867 and we're left with 336.
Append the next digit (9) from the dividend to 336 and continue with: 3369 / 531

Step 4:
531 can be fit into 3369 6 times, resulting in a remainder of 183.
Use 6 as the next digit of our solution. 
Result so far: 16.0
If we take 3186 away from 3369, we end up with 183.
Append the next digit (4) from the dividend to 183 and continue with: 1834 / 531

Moving on to step 5:
The number 531 fits into 1834 3 times, leaving a remainder of 241.
Use 3 as the next digit of our solution. 
Result so far: 163.0
The remainder is 241 after subtracting 1593 from 1834.
Grab the next digit (3) from the dividend, add it to 241, then carry on: 2413 / 531

On to step 6:
When dividing 2413 by 531, we get 4 with a remainder of 289.
Write down 4 as next digit of the result. 
Result so far: 1634.0
Subtract 2124 from 2413 to get 289.
Include the next digit (3) from the dividend after 289, then repeat: 2893 / 531

Moving on to step 7:
When dividing 2893 by 531, we get 5 with a remainder of 238.
Write down 5 as next digit of the result. 
Result so far: 16345.0
Subtracting 2655 from 2893 leaves us with 238.
Take the next digit (4) from the dividend and append it to 238, then repeat: 2384 / 531

Going ahead to step 8:
The number 531 fits into 2384 4 times, leaving a remainder of 260.
The number 4 becomes the next digit in our result. 
Result so far: 163454.0
Subtract 2124 from 2384 to get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Let's proceed to step 9:
The number 531 fits into 2600 4 times, leaving a remainder of 476.
Write down 4 as next digit of the result. 
Result so far: 163454.4
The remainder is 476 after subtracting 2124 from 2600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

Step 10:
When dividing 4760 by 531, we get 8 with a remainder of 512.
Use 8 as the next digit of our solution. 
Result so far: 163454.48
Subtracting 4248 from 4760 leaves us with 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

Let's proceed to step 11:
5120 divided by 531 is 9 with a remainder of 341.
Record the quotient 9 as the next digit in the result. 
Result so far: 163454.489
If we take 4779 away from 5120, we end up with 341.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3410, and continue the process.

Going ahead to step 12:
If we divide 3410 by 531, we get 6 and a remainder of 224.
The number 6 becomes the next digit in our result. 
Result so far: 163454.4896
Deduct 3186 from 3410 and we're left 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.

Going ahead to step 13:
2240 divided by 531 is 4 with a remainder of 116.
Put 4 as the next digit of the answer. 
Result so far: 163454.48964
Deduct 2124 from 2240 and we're left with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

On to step 14:
1160 divided by 531 is 2 with a remainder of 98.
Use 2 as the next digit of our solution. 
Result so far: 163454.489642
Subtract 1062 from 1160 to get 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Step 15:
The number 531 fits into 980 1 times, leaving a remainder of 449.
Write down 1 as next digit of the result. 
Result so far: 163454.4896421
If we subtract 531 from 980, we get 449.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4490, and continue the process.

Moving on to step 16:
531 goes into 4490 8 times with a remainder of 242.
Put 8 as the next digit of the answer. 
Result so far: 163454.48964218
The remainder is 242 after subtracting 4248 from 4490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

The final result is 163454.48964218 with a remainder of 2.42e-07.
