We're dividing 901315 by 49 
The aim is to understand the frequency of 49 in 901315.

On to step 1:
If we divide 9 by 49, we get 0 and a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 49

Step 2:
49 goes into 90 1 times with a remainder of 41.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 49 from 90 and we're left with 41.
Take the next digit (1) from the dividend and append it to 41, then repeat: 411 / 49

Going ahead to step 3:
The number 49 fits into 411 8 times, leaving a remainder of 19.
Use 8 as the next digit of our solution. 
Result so far: 18.0
Subtract 392 from 411 to get 19.
Fetch the next digit (3) from the dividend, attach it to 19 and continue: 193 / 49

Going ahead to step 4:
If we divide 193 by 49, we get 3 and a remainder of 46.
The number 3 becomes the next digit in our result. 
Result so far: 183.0
Subtracting 147 from 193 leaves us with 46.
Fetch the next digit (1) from the dividend, attach it to 46 and continue: 461 / 49

Step 5:
461 divided by 49 is 9 with a remainder of 20.
The next digit of our result is 9. 
Result so far: 1839.0
Subtracting 441 from 461 leaves us with 20.
Grab the next digit (5) from the dividend, add it to 20, then carry on: 205 / 49

Let's proceed to step 6:
205 divided by 49 is 4 with a remainder of 9.
Put 4 as the next digit of the answer. 
Result so far: 18394.0
If we subtract 196 from 205, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 7:
The number 49 fits into 90 1 times, leaving a remainder of 41.
Put 1 as the next digit of the answer. 
Result so far: 18394.1
Deduct 49 from 90 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 8:
49 goes into 410 8 times with a remainder of 18.
Use 8 as the next digit of our solution. 
Result so far: 18394.18
If we take 392 away from 410, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 9:
49 goes into 180 3 times with a remainder of 33.
Write down 3 as next digit of the result. 
Result so far: 18394.183
Subtract 147 from 180 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 10:
When dividing 330 by 49, we get 6 with a remainder of 36.
Write down 6 as next digit of the result. 
Result so far: 18394.1836
Subtracting 294 from 330 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 11:
360 divided by 49 is 7 with a remainder of 17.
Record the quotient 7 as the next digit in the result. 
Result so far: 18394.18367
If we take 343 away from 360, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 12:
The number 49 fits into 170 3 times, leaving a remainder of 23.
The next digit of our result is 3. 
Result so far: 18394.183673
The remainder is 23 after subtracting 147 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 13:
When dividing 230 by 49, we get 4 with a remainder of 34.
Put 4 as the next digit of the answer. 
Result so far: 18394.1836734
If we subtract 196 from 230, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 14:
340 divided by 49 is 6 with a remainder of 46.
The number 6 becomes the next digit in our result. 
Result so far: 18394.18367346
Deduct 294 from 340 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

The quotient of the division is 18394.18367346, and the remainder is 4.6e-08.
