We look at the division of 55371352 by 867 
The aim is to understand the frequency of 867 in 55371352.

Going ahead to step 1:
867 goes into 5 0 times with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 867

Going ahead to step 2:
867 goes into 55 0 times with a remainder of 55.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 55 to get 55.
Grab the next digit (3) from the dividend, add it to 55, then carry on: 553 / 867

On to step 3:
The number 867 fits into 553 0 times, leaving a remainder of 553.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 553 after subtracting 0 from 553.
Append the next digit (7) from the dividend to 553 and continue with: 5537 / 867

Advancing to step 4:
If we divide 5537 by 867, we get 6 and a remainder of 335.
The next digit of our result is 6. 
Result so far: 6.0
If we take 5202 away from 5537, we end up with 335.
Grab the next digit (1) from the dividend, add it to 335, then carry on: 3351 / 867

Advancing to step 5:
867 can be fit into 3351 3 times, resulting in a remainder of 750.
Record the quotient 3 as the next digit in the result. 
Result so far: 63.0
Subtract 2601 from 3351 to get 750.
Append the next digit (3) from the dividend to 750 and continue with: 7503 / 867

On to step 6:
7503 divided by 867 is 8 with a remainder of 567.
Use 8 as the next digit of our solution. 
Result so far: 638.0
If we take 6936 away from 7503, we end up with 567.
Bring next digit (5) of the dividend behind the 567 and repeat the process: 5675 / 867

On to step 7:
867 can be fit into 5675 6 times, resulting in a remainder of 473.
The next digit of our result is 6. 
Result so far: 6386.0
If we subtract 5202 from 5675, we get 473.
Bring next digit (2) of the dividend behind the 473 and repeat the process: 4732 / 867

Advancing to step 8:
When dividing 4732 by 867, we get 5 with a remainder of 397.
The number 5 becomes the next digit in our result. 
Result so far: 63865.0
If we subtract 4335 from 4732, we get 397.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3970, and continue the process.

Step 9:
The number 867 fits into 3970 4 times, leaving a remainder of 502.
Write down 4 as next digit of the result. 
Result so far: 63865.4
Subtract 3468 from 3970 to get 502.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5020, and continue the process.

Step 10:
The number 867 fits into 5020 5 times, leaving a remainder of 685.
Put 5 as the next digit of the answer. 
Result so far: 63865.45
The remainder is 685 after subtracting 4335 from 5020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6850, and continue the process.

Advancing to step 11:
The number 867 fits into 6850 7 times, leaving a remainder of 781.
Record the quotient 7 as the next digit in the result. 
Result so far: 63865.457
The remainder is 781 after subtracting 6069 from 6850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7810, and continue the process.

Moving on to step 12:
867 goes into 7810 9 times with a remainder of 7.
Record the quotient 9 as the next digit in the result. 
Result so far: 63865.4579
Subtracting 7803 from 7810 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 13:
The number 867 fits into 70 0 times, leaving a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 63865.4579
Subtract 0 from 70 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 14:
700 divided by 867 is 0 with a remainder of 700.
Use 0 as the next digit of our solution. 
Result so far: 63865.4579
Subtract 0 from 700 to get 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

The final outcome is 63865.4579, with a leftover of 7e-05.
