71498152 ÷ 49 
The aim is to understand the frequency of 49 in 71498152.

On to step 1:
The number 49 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 49

Let's proceed to step 2:
The number 49 fits into 71 1 times, leaving a remainder of 22.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 49 from 71, we get 22.
Grab the next digit (4) from the dividend, add it to 22, then carry on: 224 / 49

Advancing to step 3:
When dividing 224 by 49, we get 4 with a remainder of 28.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Subtracting 196 from 224 leaves us with 28.
Include the next digit (9) from the dividend after 28, then repeat: 289 / 49

Advancing to step 4:
When dividing 289 by 49, we get 5 with a remainder of 44.
The next digit of our result is 5. 
Result so far: 145.0
The remainder is 44 after subtracting 245 from 289.
Append the next digit (8) from the dividend to 44 and continue with: 448 / 49

Moving on to step 5:
448 divided by 49 is 9 with a remainder of 7.
Write down 9 as next digit of the result. 
Result so far: 1459.0
The remainder is 7 after subtracting 441 from 448.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 49

Advancing to step 6:
49 can be fit into 71 1 times, resulting in a remainder of 22.
Put 1 as the next digit of the answer. 
Result so far: 14591.0
Subtracting 49 from 71 leaves us with 22.
Fetch the next digit (5) from the dividend, attach it to 22 and continue: 225 / 49

Step 7:
If we divide 225 by 49, we get 4 and a remainder of 29.
Write down 4 as next digit of the result. 
Result so far: 145914.0
Deduct 196 from 225 and we're left with 29.
Bring next digit (2) of the dividend behind the 29 and repeat the process: 292 / 49

Moving on to step 8:
When dividing 292 by 49, we get 5 with a remainder of 47.
The next digit of our result is 5. 
Result so far: 1459145.0
If we take 245 away from 292, we end up with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Moving on to step 9:
If we divide 470 by 49, we get 9 and a remainder of 29.
Put 9 as the next digit of the answer. 
Result so far: 1459145.9
If we subtract 441 from 470, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 10:
290 divided by 49 is 5 with a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 1459145.95
Deduct 245 from 290 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 11:
If we divide 450 by 49, we get 9 and a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 1459145.959
The remainder is 9 after subtracting 441 from 450.
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 12:
49 goes into 90 1 times with a remainder of 41.
The number 1 becomes the next digit in our result. 
Result so far: 1459145.9591
Subtracting 49 from 90 leaves us 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.

Advancing to step 13:
49 can be fit into 410 8 times, resulting in a remainder of 18.
The next digit of our result is 8. 
Result so far: 1459145.95918
The remainder is 18 after subtracting 392 from 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 14:
49 goes into 180 3 times with a remainder of 33.
Put 3 as the next digit of the answer. 
Result so far: 1459145.959183
If we take 147 away from 180, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Advancing to step 15:
330 divided by 49 is 6 with a remainder of 36.
Record the quotient 6 as the next digit in the result. 
Result so far: 1459145.9591836
The remainder is 36 after subtracting 294 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 16:
If we divide 360 by 49, we get 7 and a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 1459145.95918367
The remainder is 17 after subtracting 343 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Our division results in 1459145.95918367 with a remaining 1.7e-08.
