We look at the division of 86416888 by 379 
The aim is to understand the frequency of 379 in 86416888.

Going ahead to step 1:
If we divide 8 by 379, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 379

Step 2:
If we divide 86 by 379, we get 0 and a remainder of 86.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 86 to get 86.
Bring next digit (4) of the dividend behind the 86 and repeat the process: 864 / 379

Moving on to step 3:
379 can be fit into 864 2 times, resulting in a remainder of 106.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 106 after subtracting 758 from 864.
Append the next digit (1) from the dividend to 106 and continue with: 1061 / 379

Step 4:
The number 379 fits into 1061 2 times, leaving a remainder of 303.
Use 2 as the next digit of our solution. 
Result so far: 22.0
If we take 758 away from 1061, we end up with 303.
Bring next digit (6) of the dividend behind the 303 and repeat the process: 3036 / 379

Step 5:
379 goes into 3036 8 times with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 228.0
The remainder is 4 after subtracting 3032 from 3036.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 379

Advancing to step 6:
379 goes into 48 0 times with a remainder of 48.
Write down 0 as next digit of the result. 
Result so far: 2280.0
The remainder is 48 after subtracting 0 from 48.
Fetch the next digit (8) from the dividend, attach it to 48 and continue: 488 / 379

On to step 7:
379 goes into 488 1 times with a remainder of 109.
The next digit of our result is 1. 
Result so far: 22801.0
Deduct 379 from 488 and we're left with 109.
Grab the next digit (8) from the dividend, add it to 109, then carry on: 1098 / 379

Moving on to step 8:
1098 divided by 379 is 2 with a remainder of 340.
Write down 2 as next digit of the result. 
Result so far: 228012.0
The remainder is 340 after subtracting 758 from 1098.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Let's proceed to step 9:
379 goes into 3400 8 times with a remainder of 368.
The number 8 becomes the next digit in our result. 
Result so far: 228012.8
Subtract 3032 from 3400 to get 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Moving on to step 10:
The number 379 fits into 3680 9 times, leaving a remainder of 269.
The next digit of our result is 9. 
Result so far: 228012.89
Subtracting 3411 from 3680 leaves us with 269.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2690, and continue the process.

Advancing to step 11:
When dividing 2690 by 379, we get 7 with a remainder of 37.
Record the quotient 7 as the next digit in the result. 
Result so far: 228012.897
Deduct 2653 from 2690 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 12:
When dividing 370 by 379, we get 0 with a remainder of 370.
Record the quotient 0 as the next digit in the result. 
Result so far: 228012.897
The remainder is 370 after subtracting 0 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Step 13:
3700 divided by 379 is 9 with a remainder of 289.
Record the quotient 9 as the next digit in the result. 
Result so far: 228012.89709
Subtracting 3411 from 3700 leaves us with 289.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2890, and continue the process.

Moving on to step 14:
379 goes into 2890 7 times with a remainder of 237.
Record the quotient 7 as the next digit in the result. 
Result so far: 228012.897097
Subtract 2653 from 2890 to get 237.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2370, and continue the process.

Let's proceed to step 15:
379 goes into 2370 6 times with a remainder of 96.
Put 6 as the next digit of the answer. 
Result so far: 228012.8970976
Subtracting 2274 from 2370 leaves us with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Going ahead to step 16:
The number 379 fits into 960 2 times, leaving a remainder of 202.
Record the quotient 2 as the next digit in the result. 
Result so far: 228012.89709762
Subtracting 758 from 960 leaves us with 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

The final result is 228012.89709762 with a remainder of 2.02e-07.
