Let's divide 49660599 by 861
The aim is to understand the frequency of 861 in 49660599.

Step 1:
4 divided by 861 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (9) from the dividend and append it to 4, then repeat: 49 / 861

Let's proceed to step 2:
49 divided by 861 is 0 with a remainder of 49.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 49 and we're left with 49.
Grab the next digit (6) from the dividend, add it to 49, then carry on: 496 / 861

Let's proceed to step 3:
496 divided by 861 is 0 with a remainder of 496.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 496 leaves us with 496.
Include the next digit (6) from the dividend after 496, then repeat: 4966 / 861

Step 4:
The number 861 fits into 4966 5 times, leaving a remainder of 661.
The next digit of our result is 5. 
Result so far: 5.0
If we subtract 4305 from 4966, we get 661.
Bring next digit (0) of the dividend behind the 661 and repeat the process: 6610 / 861

On to step 5:
If we divide 6610 by 861, we get 7 and a remainder of 583.
Write down 7 as next digit of the result. 
Result so far: 57.0
Deduct 6027 from 6610 and we're left with 583.
Append the next digit (5) from the dividend to 583 and continue with: 5835 / 861

Moving on to step 6:
The number 861 fits into 5835 6 times, leaving a remainder of 669.
The next digit of our result is 6. 
Result so far: 576.0
The remainder is 669 after subtracting 5166 from 5835.
Append the next digit (9) from the dividend to 669 and continue with: 6699 / 861

Let's proceed to step 7:
When dividing 6699 by 861, we get 7 with a remainder of 672.
Put 7 as the next digit of the answer. 
Result so far: 5767.0
Deduct 6027 from 6699 and we're left with 672.
Append the next digit (9) from the dividend to 672 and continue with: 6729 / 861

On to step 8:
861 goes into 6729 7 times with a remainder of 702.
The next digit of our result is 7. 
Result so far: 57677.0
The remainder is 702 after subtracting 6027 from 6729.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7020, and continue the process.

Advancing to step 9:
If we divide 7020 by 861, we get 8 and a remainder of 132.
Use 8 as the next digit of our solution. 
Result so far: 57677.8
If we subtract 6888 from 7020, we get 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Step 10:
861 goes into 1320 1 times with a remainder of 459.
The number 1 becomes the next digit in our result. 
Result so far: 57677.81
If we subtract 861 from 1320, we get 459.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4590, and continue the process.

Moving on to step 11:
4590 divided by 861 is 5 with a remainder of 285.
Put 5 as the next digit of the answer. 
Result so far: 57677.815
Deduct 4305 from 4590 and we're left with 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Step 12:
When dividing 2850 by 861, we get 3 with a remainder of 267.
Put 3 as the next digit of the answer. 
Result so far: 57677.8153
Deduct 2583 from 2850 and we're left with 267.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2670, and continue the process.

On to step 13:
861 can be fit into 2670 3 times, resulting in a remainder of 87.
The number 3 becomes the next digit in our result. 
Result so far: 57677.81533
Deduct 2583 from 2670 and we're left with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

After the division, we end up with 57677.81533 and a remainder of 8.7e-05.
