We look at the division of 86623614 by 918 
The aim is to understand the frequency of 918 in 86623614.

Advancing to step 1:
When dividing 8 by 918, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 918

Let's proceed to step 2:
When dividing 86 by 918, we get 0 with a remainder of 86.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 86 and we're left with 86.
Bring next digit (6) of the dividend behind the 86 and repeat the process: 866 / 918

Advancing to step 3:
918 goes into 866 0 times with a remainder of 866.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 866 after subtracting 0 from 866.
Include the next digit (2) from the dividend after 866, then repeat: 8662 / 918

Step 4:
8662 divided by 918 is 9 with a remainder of 400.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we subtract 8262 from 8662, we get 400.
Grab the next digit (3) from the dividend, add it to 400, then carry on: 4003 / 918

Advancing to step 5:
4003 divided by 918 is 4 with a remainder of 331.
Put 4 as the next digit of the answer. 
Result so far: 94.0
If we subtract 3672 from 4003, we get 331.
Append the next digit (6) from the dividend to 331 and continue with: 3316 / 918

Going ahead to step 6:
The number 918 fits into 3316 3 times, leaving a remainder of 562.
The number 3 becomes the next digit in our result. 
Result so far: 943.0
Deduct 2754 from 3316 and we're left with 562.
Fetch the next digit (1) from the dividend, attach it to 562 and continue: 5621 / 918

Let's proceed to step 7:
5621 divided by 918 is 6 with a remainder of 113.
Write down 6 as next digit of the result. 
Result so far: 9436.0
Subtract 5508 from 5621 to get 113.
Bring next digit (4) of the dividend behind the 113 and repeat the process: 1134 / 918

Moving on to step 8:
When dividing 1134 by 918, we get 1 with a remainder of 216.
Use 1 as the next digit of our solution. 
Result so far: 94361.0
Subtract 918 from 1134 to get 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Step 9:
918 goes into 2160 2 times with a remainder of 324.
The next digit of our result is 2. 
Result so far: 94361.2
Deduct 1836 from 2160 and we're left with 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Let's proceed to step 10:
918 goes into 3240 3 times with a remainder of 486.
Record the quotient 3 as the next digit in the result. 
Result so far: 94361.23
Subtracting 2754 from 3240 leaves us with 486.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4860, and continue the process.

On to step 11:
When dividing 4860 by 918, we get 5 with a remainder of 270.
Record the quotient 5 as the next digit in the result. 
Result so far: 94361.235
Subtract 4590 from 4860 to get 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

On to step 12:
918 can be fit into 2700 2 times, resulting in a remainder of 864.
Record the quotient 2 as the next digit in the result. 
Result so far: 94361.2352
If we take 1836 away from 2700, we end up with 864.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8640, and continue the process.

Moving on to step 13:
If we divide 8640 by 918, we get 9 and a remainder of 378.
Write down 9 as next digit of the result. 
Result so far: 94361.23529
If we take 8262 away from 8640, we end up with 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

On to step 14:
The number 918 fits into 3780 4 times, leaving a remainder of 108.
Record the quotient 4 as the next digit in the result. 
Result so far: 94361.235294
If we take 3672 away from 3780, we end up with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Let's proceed to step 15:
The number 918 fits into 1080 1 times, leaving a remainder of 162.
Put 1 as the next digit of the answer. 
Result so far: 94361.2352941
The remainder is 162 after subtracting 918 from 1080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Moving on to step 16:
918 goes into 1620 1 times with a remainder of 702.
Record the quotient 1 as the next digit in the result. 
Result so far: 94361.23529411
The remainder is 702 after subtracting 918 from 1620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7020, and continue the process.

After the division, we end up with 94361.23529411 and a remainder of 7.02e-07.
