We're dividing 897951 by 49 
The aim is to understand the frequency of 49 in 897951.

On to step 1:
49 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 49

Let's proceed to step 2:
49 goes into 89 1 times with a remainder of 40.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 49 from 89, we get 40.
Grab the next digit (7) from the dividend, add it to 40, then carry on: 407 / 49

Moving on to step 3:
407 divided by 49 is 8 with a remainder of 15.
Write down 8 as next digit of the result. 
Result so far: 18.0
If we take 392 away from 407, we end up with 15.
Take the next digit (9) from the dividend and append it to 15, then repeat: 159 / 49

Going ahead to step 4:
49 can be fit into 159 3 times, resulting in a remainder of 12.
The next digit of our result is 3. 
Result so far: 183.0
Deduct 147 from 159 and we're left with 12.
Fetch the next digit (5) from the dividend, attach it to 12 and continue: 125 / 49

Moving on to step 5:
49 can be fit into 125 2 times, resulting in a remainder of 27.
Use 2 as the next digit of our solution. 
Result so far: 1832.0
If we subtract 98 from 125, we get 27.
Grab the next digit (1) from the dividend, add it to 27, then carry on: 271 / 49

Moving on to step 6:
49 can be fit into 271 5 times, resulting in a remainder of 26.
The number 5 becomes the next digit in our result. 
Result so far: 18325.0
The remainder is 26 after subtracting 245 from 271.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 7:
49 can be fit into 260 5 times, resulting in a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 18325.5
Subtract 245 from 260 to 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.

On to step 8:
150 divided by 49 is 3 with a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 18325.53
Subtract 147 from 150 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 9:
49 goes into 30 0 times with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 18325.53
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 10:
The number 49 fits into 300 6 times, leaving a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 18325.5306
The remainder is 6 after subtracting 294 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 11:
49 goes into 60 1 times with a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 18325.53061
If we take 49 away from 60, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 12:
When dividing 110 by 49, we get 2 with a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 18325.530612
The remainder is 12 after subtracting 98 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 13:
120 divided by 49 is 2 with a remainder of 22.
Record the quotient 2 as the next digit in the result. 
Result so far: 18325.5306122
If we take 98 away from 120, we end up 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.

After the division, we end up with 18325.5306122 and a remainder of 2.2e-07.
