We look at the division of 24951906 by 861 
The aim is to understand the frequency of 861 in 24951906.

Going ahead to step 1:
861 goes into 2 0 times with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (4) from the dividend after 2, then repeat: 24 / 861

On to step 2:
861 can be fit into 24 0 times, resulting in a remainder of 24.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 24, we end up with 24.
Fetch the next digit (9) from the dividend, attach it to 24 and continue: 249 / 861

On to step 3:
The number 861 fits into 249 0 times, leaving a remainder of 249.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 249, we get 249.
Append the next digit (5) from the dividend to 249 and continue with: 2495 / 861

Step 4:
861 can be fit into 2495 2 times, resulting in a remainder of 773.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 1722 from 2495 and we're left with 773.
Take the next digit (1) from the dividend and append it to 773, then repeat: 7731 / 861

On to step 5:
7731 divided by 861 is 8 with a remainder of 843.
Write down 8 as next digit of the result. 
Result so far: 28.0
Subtracting 6888 from 7731 leaves us with 843.
Include the next digit (9) from the dividend after 843, then repeat: 8439 / 861

Moving on to step 6:
861 goes into 8439 9 times with a remainder of 690.
Write down 9 as next digit of the result. 
Result so far: 289.0
Subtracting 7749 from 8439 leaves us with 690.
Take the next digit (0) from the dividend and append it to 690, then repeat: 6900 / 861

Going ahead to step 7:
861 can be fit into 6900 8 times, resulting in a remainder of 12.
The next digit of our result is 8. 
Result so far: 2898.0
Subtracting 6888 from 6900 leaves us with 12.
Bring next digit (6) of the dividend behind the 12 and repeat the process: 126 / 861

Going ahead to step 8:
861 can be fit into 126 0 times, resulting in a remainder of 126.
Write down 0 as next digit of the result. 
Result so far: 28980.0
If we subtract 0 from 126, we get 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Advancing to step 9:
1260 divided by 861 is 1 with a remainder of 399.
The number 1 becomes the next digit in our result. 
Result so far: 28980.1
Subtract 861 from 1260 to get 399.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3990, and continue the process.

On to step 10:
3990 divided by 861 is 4 with a remainder of 546.
The number 4 becomes the next digit in our result. 
Result so far: 28980.14
The remainder is 546 after subtracting 3444 from 3990.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5460, and continue the process.

Going ahead to step 11:
The number 861 fits into 5460 6 times, leaving a remainder of 294.
Put 6 as the next digit of the answer. 
Result so far: 28980.146
Subtracting 5166 from 5460 leaves us with 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Step 12:
The number 861 fits into 2940 3 times, leaving a remainder of 357.
Record the quotient 3 as the next digit in the result. 
Result so far: 28980.1463
Subtract 2583 from 2940 to get 357.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3570, and continue the process.

Moving on to step 13:
The number 861 fits into 3570 4 times, leaving a remainder of 126.
Write down 4 as next digit of the result. 
Result so far: 28980.14634
Subtracting 3444 from 3570 leaves us with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Going ahead to step 14:
1260 divided by 861 is 1 with a remainder of 399.
Put 1 as the next digit of the answer. 
Result so far: 28980.146341
Subtract 861 from 1260 to get 399.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3990, and continue the process.

Step 15:
If we divide 3990 by 861, we get 4 and a remainder of 546.
Write down 4 as next digit of the result. 
Result so far: 28980.1463414
Subtracting 3444 from 3990 leaves us with 546.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5460, and continue the process.

Going ahead to step 16:
861 can be fit into 5460 6 times, resulting in a remainder of 294.
Put 6 as the next digit of the answer. 
Result so far: 28980.14634146
Subtract 5166 from 5460 to get 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.
