We look at the division of 86915695 by 546 
The aim is to understand the frequency of 546 in 86915695.

On to step 1:
546 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 546

On to step 2:
The number 546 fits into 86 0 times, leaving a remainder of 86.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 86 after subtracting 0 from 86.
Include the next digit (9) from the dividend after 86, then repeat: 869 / 546

Step 3:
When dividing 869 by 546, we get 1 with a remainder of 323.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 546 from 869 leaves us with 323.
Grab the next digit (1) from the dividend, add it to 323, then carry on: 3231 / 546

Let's proceed to step 4:
If we divide 3231 by 546, we get 5 and a remainder of 501.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Deduct 2730 from 3231 and we're left with 501.
Append the next digit (5) from the dividend to 501 and continue with: 5015 / 546

Going ahead to step 5:
When dividing 5015 by 546, we get 9 with a remainder of 101.
The next digit of our result is 9. 
Result so far: 159.0
Deduct 4914 from 5015 and we're left with 101.
Append the next digit (6) from the dividend to 101 and continue with: 1016 / 546

Moving on to step 6:
The number 546 fits into 1016 1 times, leaving a remainder of 470.
Put 1 as the next digit of the answer. 
Result so far: 1591.0
The remainder is 470 after subtracting 546 from 1016.
Take the next digit (9) from the dividend and append it to 470, then repeat: 4709 / 546

Moving on to step 7:
546 can be fit into 4709 8 times, resulting in a remainder of 341.
Put 8 as the next digit of the answer. 
Result so far: 15918.0
If we take 4368 away from 4709, we end up with 341.
Append the next digit (5) from the dividend to 341 and continue with: 3415 / 546

Going ahead to step 8:
When dividing 3415 by 546, we get 6 with a remainder of 139.
Put 6 as the next digit of the answer. 
Result so far: 159186.0
Subtract 3276 from 3415 to get 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

Step 9:
546 can be fit into 1390 2 times, resulting in a remainder of 298.
Use 2 as the next digit of our solution. 
Result so far: 159186.2
Deduct 1092 from 1390 and we're left with 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

On to step 10:
The number 546 fits into 2980 5 times, leaving a remainder of 250.
The number 5 becomes the next digit in our result. 
Result so far: 159186.25
If we take 2730 away from 2980, we end up with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

On to step 11:
When dividing 2500 by 546, we get 4 with a remainder of 316.
Record the quotient 4 as the next digit in the result. 
Result so far: 159186.254
If we subtract 2184 from 2500, we get 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

On to step 12:
546 can be fit into 3160 5 times, resulting in a remainder of 430.
The next digit of our result is 5. 
Result so far: 159186.2545
The remainder is 430 after subtracting 2730 from 3160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Step 13:
When dividing 4300 by 546, we get 7 with a remainder of 478.
Use 7 as the next digit of our solution. 
Result so far: 159186.25457
If we subtract 3822 from 4300, we get 478.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4780, and continue the process.

Step 14:
The number 546 fits into 4780 8 times, leaving a remainder of 412.
Use 8 as the next digit of our solution. 
Result so far: 159186.254578
Subtract 4368 from 4780 to get 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

Advancing to step 15:
When dividing 4120 by 546, we get 7 with a remainder of 298.
Put 7 as the next digit of the answer. 
Result so far: 159186.2545787
Subtracting 3822 from 4120 leaves us with 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Let's proceed to step 16:
The number 546 fits into 2980 5 times, leaving a remainder of 250.
The number 5 becomes the next digit in our result. 
Result so far: 159186.25457875
If we subtract 2730 from 2980, we get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

The final outcome is 159186.25457875, with a leftover of 2.5e-07.
