858610 ÷ 49 
The aim is to understand the frequency of 49 in 858610.

Moving on to step 1:
49 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 49

Going ahead to step 2:
49 can be fit into 85 1 times, resulting in a remainder of 36.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 49 from 85, we get 36.
Append the next digit (8) from the dividend to 36 and continue with: 368 / 49

On to step 3:
When dividing 368 by 49, we get 7 with a remainder of 25.
The next digit of our result is 7. 
Result so far: 17.0
Subtracting 343 from 368 leaves us with 25.
Bring next digit (6) of the dividend behind the 25 and repeat the process: 256 / 49

Advancing to step 4:
When dividing 256 by 49, we get 5 with a remainder of 11.
The number 5 becomes the next digit in our result. 
Result so far: 175.0
If we take 245 away from 256, we end up with 11.
Grab the next digit (1) from the dividend, add it to 11, then carry on: 111 / 49

Step 5:
49 goes into 111 2 times with a remainder of 13.
Use 2 as the next digit of our solution. 
Result so far: 1752.0
Deduct 98 from 111 and we're left with 13.
Take the next digit (0) from the dividend and append it to 13, then repeat: 130 / 49

Step 6:
130 divided by 49 is 2 with a remainder of 32.
The number 2 becomes the next digit in our result. 
Result so far: 17522.0
Deduct 98 from 130 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 7:
When dividing 320 by 49, we get 6 with a remainder of 26.
Put 6 as the next digit of the answer. 
Result so far: 17522.6
If we subtract 294 from 320, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 8:
When dividing 260 by 49, we get 5 with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 17522.65
If we subtract 245 from 260, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 9:
49 can be fit into 150 3 times, resulting in a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 17522.653
If we take 147 away from 150, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 10:
49 can be fit into 30 0 times, resulting in a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 17522.653
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 11:
49 can be fit into 300 6 times, resulting in a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 17522.65306
Deduct 294 from 300 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 12:
49 can be fit into 60 1 times, resulting in a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 17522.653061
The remainder is 11 after subtracting 49 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 13:
If we divide 110 by 49, we get 2 and a remainder of 12.
The next digit of our result is 2. 
Result so far: 17522.6530612
If we subtract 98 from 110, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 14:
When dividing 120 by 49, we get 2 with a remainder of 22.
Use 2 as the next digit of our solution. 
Result so far: 17522.65306122
Subtracting 98 from 120 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The final outcome is 17522.65306122, with a leftover of 2.2e-08.
