We look at the division of 899637 by 49 
The aim is to understand the frequency of 49 in 899637.

On to step 1:
The number 49 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 49

Step 2:
If we divide 89 by 49, we get 1 and a remainder of 40.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 49 from 89, we get 40.
Grab the next digit (9) from the dividend, add it to 40, then carry on: 409 / 49

Moving on to step 3:
When dividing 409 by 49, we get 8 with a remainder of 17.
Write down 8 as next digit of the result. 
Result so far: 18.0
The remainder is 17 after subtracting 392 from 409.
Grab the next digit (6) from the dividend, add it to 17, then carry on: 176 / 49

On to step 4:
The number 49 fits into 176 3 times, leaving a remainder of 29.
Put 3 as the next digit of the answer. 
Result so far: 183.0
The remainder is 29 after subtracting 147 from 176.
Fetch the next digit (3) from the dividend, attach it to 29 and continue: 293 / 49

On to step 5:
49 goes into 293 5 times with a remainder of 48.
The number 5 becomes the next digit in our result. 
Result so far: 1835.0
Subtracting 245 from 293 leaves us with 48.
Include the next digit (7) from the dividend after 48, then repeat: 487 / 49

Step 6:
The number 49 fits into 487 9 times, leaving a remainder of 46.
Use 9 as the next digit of our solution. 
Result so far: 18359.0
Subtract 441 from 487 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 7:
When dividing 460 by 49, we get 9 with a remainder of 19.
The number 9 becomes the next digit in our result. 
Result so far: 18359.9
If we subtract 441 from 460, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 8:
The number 49 fits into 190 3 times, leaving a remainder of 43.
Put 3 as the next digit of the answer. 
Result so far: 18359.93
If we take 147 away from 190, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Step 9:
49 can be fit into 430 8 times, resulting in a remainder of 38.
The next digit of our result is 8. 
Result so far: 18359.938
If we subtract 392 from 430, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 10:
49 can be fit into 380 7 times, resulting in a remainder of 37.
The next digit of our result is 7. 
Result so far: 18359.9387
Deduct 343 from 380 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 11:
When dividing 370 by 49, we get 7 with a remainder of 27.
The number 7 becomes the next digit in our result. 
Result so far: 18359.93877
If we take 343 away from 370, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

The quotient of the division is 18359.93877, and the remainder is 2.7e-05.
