61780362 divided by 49 
The aim is to understand the frequency of 49 in 61780362.

Step 1:
49 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (1) from the dividend and append it to 6, then repeat: 61 / 49

Moving on to step 2:
49 goes into 61 1 times with a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 12 after subtracting 49 from 61.
Take the next digit (7) from the dividend and append it to 12, then repeat: 127 / 49

Moving on to step 3:
The number 49 fits into 127 2 times, leaving a remainder of 29.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtract 98 from 127 to get 29.
Grab the next digit (8) from the dividend, add it to 29, then carry on: 298 / 49

Moving on to step 4:
49 can be fit into 298 6 times, resulting in a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 126.0
Deduct 294 from 298 and we're left with 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 49

Step 5:
When dividing 40 by 49, we get 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 1260.0
The remainder is 40 after subtracting 0 from 40.
Include the next digit (3) from the dividend after 40, then repeat: 403 / 49

Moving on to step 6:
If we divide 403 by 49, we get 8 and a remainder of 11.
The next digit of our result is 8. 
Result so far: 12608.0
Subtract 392 from 403 to get 11.
Bring next digit (6) of the dividend behind the 11 and repeat the process: 116 / 49

Going ahead to step 7:
49 can be fit into 116 2 times, resulting in a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 126082.0
The remainder is 18 after subtracting 98 from 116.
Append the next digit (2) from the dividend to 18 and continue with: 182 / 49

On to step 8:
182 divided by 49 is 3 with a remainder of 35.
The next digit of our result is 3. 
Result so far: 1260823.0
The remainder is 35 after subtracting 147 from 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 9:
When dividing 350 by 49, we get 7 with a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 1260823.7
Subtracting 343 from 350 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 10:
70 divided by 49 is 1 with a remainder of 21.
Write down 1 as next digit of the result. 
Result so far: 1260823.71
Deduct 49 from 70 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 11:
When dividing 210 by 49, we get 4 with a remainder of 14.
The number 4 becomes the next digit in our result. 
Result so far: 1260823.714
If we take 196 away from 210, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 12:
The number 49 fits into 140 2 times, leaving a remainder of 42.
Use 2 as the next digit of our solution. 
Result so far: 1260823.7142
If we subtract 98 from 140, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 13:
49 can be fit into 420 8 times, resulting in a remainder of 28.
Use 8 as the next digit of our solution. 
Result so far: 1260823.71428
Subtracting 392 from 420 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 14:
If we divide 280 by 49, we get 5 and a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 1260823.714285
If we take 245 away from 280, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 15:
When dividing 350 by 49, we get 7 with a remainder of 7.
The next digit of our result is 7. 
Result so far: 1260823.7142857
If we subtract 343 from 350, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 16:
70 divided by 49 is 1 with a remainder of 21.
The next digit of our result is 1. 
Result so far: 1260823.71428571
If we subtract 49 from 70, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

The final outcome is 1260823.71428571, with a leftover of 2.1e-08.
