We're dividing 53191080 by 867 
The aim is to understand the frequency of 867 in 53191080.

Moving on to step 1:
5 divided by 867 is 0 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 (3) from the dividend and append it to 5, then repeat: 53 / 867

Let's proceed to step 2:
When dividing 53 by 867, we get 0 with a remainder of 53.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 53, we end up with 53.
Bring next digit (1) of the dividend behind the 53 and repeat the process: 531 / 867

Moving on to step 3:
The number 867 fits into 531 0 times, leaving a remainder of 531.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 531 leaves us with 531.
Bring next digit (9) of the dividend behind the 531 and repeat the process: 5319 / 867

Advancing to step 4:
867 goes into 5319 6 times with a remainder of 117.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
The remainder is 117 after subtracting 5202 from 5319.
Fetch the next digit (1) from the dividend, attach it to 117 and continue: 1171 / 867

Let's proceed to step 5:
The number 867 fits into 1171 1 times, leaving a remainder of 304.
Use 1 as the next digit of our solution. 
Result so far: 61.0
Subtract 867 from 1171 to get 304.
Append the next digit (0) from the dividend to 304 and continue with: 3040 / 867

Advancing to step 6:
3040 divided by 867 is 3 with a remainder of 439.
Put 3 as the next digit of the answer. 
Result so far: 613.0
Subtract 2601 from 3040 to get 439.
Fetch the next digit (8) from the dividend, attach it to 439 and continue: 4398 / 867

Step 7:
867 can be fit into 4398 5 times, resulting in a remainder of 63.
Record the quotient 5 as the next digit in the result. 
Result so far: 6135.0
Deduct 4335 from 4398 and we're left with 63.
Grab the next digit (0) from the dividend, add it to 63, then carry on: 630 / 867

Going ahead to step 8:
The number 867 fits into 630 0 times, leaving a remainder of 630.
Record the quotient 0 as the next digit in the result. 
Result so far: 61350.0
Deduct 0 from 630 and we're left with 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

Step 9:
6300 divided by 867 is 7 with a remainder of 231.
Put 7 as the next digit of the answer. 
Result so far: 61350.7
If we subtract 6069 from 6300, we get 231.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2310, and continue the process.

Step 10:
2310 divided by 867 is 2 with a remainder of 576.
Record the quotient 2 as the next digit in the result. 
Result so far: 61350.72
Subtracting 1734 from 2310 leaves us with 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

Let's proceed to step 11:
When dividing 5760 by 867, we get 6 with a remainder of 558.
Record the quotient 6 as the next digit in the result. 
Result so far: 61350.726
Deduct 5202 from 5760 and we're left with 558.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5580, and continue the process.

Advancing to step 12:
When dividing 5580 by 867, we get 6 with a remainder of 378.
The number 6 becomes the next digit in our result. 
Result so far: 61350.7266
The remainder is 378 after subtracting 5202 from 5580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

The final result is 61350.7266 with a remainder of 0.00378.
