We're dividing 15807374 by 567 
The aim is to understand the frequency of 567 in 15807374.

Going ahead to step 1:
567 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 567

On to step 2:
567 goes into 15 0 times with a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 15 to get 15.
Take the next digit (8) from the dividend and append it to 15, then repeat: 158 / 567

Moving on to step 3:
The number 567 fits into 158 0 times, leaving a remainder of 158.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 158 to get 158.
Append the next digit (0) from the dividend to 158 and continue with: 1580 / 567

Going ahead to step 4:
567 goes into 1580 2 times with a remainder of 446.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 1134 from 1580 to get 446.
Fetch the next digit (7) from the dividend, attach it to 446 and continue: 4467 / 567

On to step 5:
567 goes into 4467 7 times with a remainder of 498.
Use 7 as the next digit of our solution. 
Result so far: 27.0
Deduct 3969 from 4467 and we're left with 498.
Take the next digit (3) from the dividend and append it to 498, then repeat: 4983 / 567

Moving on to step 6:
The number 567 fits into 4983 8 times, leaving a remainder of 447.
The next digit of our result is 8. 
Result so far: 278.0
Subtract 4536 from 4983 to get 447.
Take the next digit (7) from the dividend and append it to 447, then repeat: 4477 / 567

On to step 7:
4477 divided by 567 is 7 with a remainder of 508.
Use 7 as the next digit of our solution. 
Result so far: 2787.0
Deduct 3969 from 4477 and we're left with 508.
Fetch the next digit (4) from the dividend, attach it to 508 and continue: 5084 / 567

Going ahead to step 8:
5084 divided by 567 is 8 with a remainder of 548.
Put 8 as the next digit of the answer. 
Result so far: 27878.0
Subtracting 4536 from 5084 leaves us with 548.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5480, and continue the process.

Moving on to step 9:
5480 divided by 567 is 9 with a remainder of 377.
Record the quotient 9 as the next digit in the result. 
Result so far: 27878.9
Deduct 5103 from 5480 and we're left with 377.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3770, and continue the process.

On to step 10:
3770 divided by 567 is 6 with a remainder of 368.
Record the quotient 6 as the next digit in the result. 
Result so far: 27878.96
Subtracting 3402 from 3770 leaves us with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Step 11:
When dividing 3680 by 567, we get 6 with a remainder of 278.
Record the quotient 6 as the next digit in the result. 
Result so far: 27878.966
Subtract 3402 from 3680 to get 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

The final result is 27878.966 with a remainder of 0.0278.
