Let's divide 51074242 by 861
The aim is to understand the frequency of 861 in 51074242.

Step 1:
861 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 861

Advancing to step 2:
51 divided by 861 is 0 with a remainder of 51.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 51 to get 51.
Bring next digit (0) of the dividend behind the 51 and repeat the process: 510 / 861

Let's proceed to step 3:
861 can be fit into 510 0 times, resulting in a remainder of 510.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 510 to get 510.
Append the next digit (7) from the dividend to 510 and continue with: 5107 / 861

Step 4:
If we divide 5107 by 861, we get 5 and a remainder of 802.
The next digit of our result is 5. 
Result so far: 5.0
Subtract 4305 from 5107 to get 802.
Take the next digit (4) from the dividend and append it to 802, then repeat: 8024 / 861

Going ahead to step 5:
The number 861 fits into 8024 9 times, leaving a remainder of 275.
The next digit of our result is 9. 
Result so far: 59.0
The remainder is 275 after subtracting 7749 from 8024.
Include the next digit (2) from the dividend after 275, then repeat: 2752 / 861

Advancing to step 6:
2752 divided by 861 is 3 with a remainder of 169.
Put 3 as the next digit of the answer. 
Result so far: 593.0
If we subtract 2583 from 2752, we get 169.
Grab the next digit (4) from the dividend, add it to 169, then carry on: 1694 / 861

On to step 7:
The number 861 fits into 1694 1 times, leaving a remainder of 833.
Record the quotient 1 as the next digit in the result. 
Result so far: 5931.0
Subtracting 861 from 1694 leaves us with 833.
Bring next digit (2) of the dividend behind the 833 and repeat the process: 8332 / 861

Let's proceed to step 8:
When dividing 8332 by 861, we get 9 with a remainder of 583.
Write down 9 as next digit of the result. 
Result so far: 59319.0
If we subtract 7749 from 8332, we get 583.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5830, and continue the process.

Moving on to step 9:
The number 861 fits into 5830 6 times, leaving a remainder of 664.
The next digit of our result is 6. 
Result so far: 59319.6
Subtract 5166 from 5830 to get 664.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6640, and continue the process.

Step 10:
861 goes into 6640 7 times with a remainder of 613.
Use 7 as the next digit of our solution. 
Result so far: 59319.67
The remainder is 613 after subtracting 6027 from 6640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6130, and continue the process.

Advancing to step 11:
If we divide 6130 by 861, we get 7 and a remainder of 103.
The number 7 becomes the next digit in our result. 
Result so far: 59319.677
If we subtract 6027 from 6130, we get 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

The quotient of the division is 59319.677, and the remainder is 0.0103.
