We look at the division of 86667052 by 354 
The aim is to understand the frequency of 354 in 86667052.

Going ahead to step 1:
354 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
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 / 354

Moving on to step 2:
If we divide 86 by 354, we get 0 and a remainder of 86.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 86 leaves us with 86.
Append the next digit (6) from the dividend to 86 and continue with: 866 / 354

Let's proceed to step 3:
866 divided by 354 is 2 with a remainder of 158.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 708 from 866 leaves us with 158.
Take the next digit (6) from the dividend and append it to 158, then repeat: 1586 / 354

Going ahead to step 4:
When dividing 1586 by 354, we get 4 with a remainder of 170.
Use 4 as the next digit of our solution. 
Result so far: 24.0
Subtract 1416 from 1586 to get 170.
Bring next digit (7) of the dividend behind the 170 and repeat the process: 1707 / 354

Let's proceed to step 5:
When dividing 1707 by 354, we get 4 with a remainder of 291.
Put 4 as the next digit of the answer. 
Result so far: 244.0
Subtracting 1416 from 1707 leaves us with 291.
Grab the next digit (0) from the dividend, add it to 291, then carry on: 2910 / 354

Let's proceed to step 6:
354 can be fit into 2910 8 times, resulting in a remainder of 78.
Use 8 as the next digit of our solution. 
Result so far: 2448.0
Subtract 2832 from 2910 to get 78.
Fetch the next digit (5) from the dividend, attach it to 78 and continue: 785 / 354

Let's proceed to step 7:
The number 354 fits into 785 2 times, leaving a remainder of 77.
The next digit of our result is 2. 
Result so far: 24482.0
The remainder is 77 after subtracting 708 from 785.
Grab the next digit (2) from the dividend, add it to 77, then carry on: 772 / 354

Advancing to step 8:
354 goes into 772 2 times with a remainder of 64.
Put 2 as the next digit of the answer. 
Result so far: 244822.0
The remainder is 64 after subtracting 708 from 772.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 9:
354 can be fit into 640 1 times, resulting in a remainder of 286.
Record the quotient 1 as the next digit in the result. 
Result so far: 244822.1
If we take 354 away from 640, we end up with 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Moving on to step 10:
If we divide 2860 by 354, we get 8 and a remainder of 28.
The next digit of our result is 8. 
Result so far: 244822.18
Deduct 2832 from 2860 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 11:
The number 354 fits into 280 0 times, leaving a remainder of 280.
Write down 0 as next digit of the result. 
Result so far: 244822.18
If we take 0 away from 280, we end up with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

On to step 12:
If we divide 2800 by 354, we get 7 and a remainder of 322.
Put 7 as the next digit of the answer. 
Result so far: 244822.1807
The remainder is 322 after subtracting 2478 from 2800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Advancing to step 13:
354 can be fit into 3220 9 times, resulting in a remainder of 34.
The next digit of our result is 9. 
Result so far: 244822.18079
The remainder is 34 after subtracting 3186 from 3220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 14:
If we divide 340 by 354, we get 0 and a remainder of 340.
Write down 0 as next digit of the result. 
Result so far: 244822.18079
Subtracting 0 from 340 leaves us with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Step 15:
When dividing 3400 by 354, we get 9 with a remainder of 214.
The number 9 becomes the next digit in our result. 
Result so far: 244822.1807909
Deduct 3186 from 3400 and we're left with 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Let's proceed to step 16:
The number 354 fits into 2140 6 times, leaving a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 244822.18079096
Deduct 2124 from 2140 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 244822.18079096, with a leftover of 1.6e-08.
