Let's divide 877681 by 49
The aim is to understand the frequency of 49 in 877681.

Advancing to step 1:
8 divided by 49 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 49

Let's proceed to step 2:
The number 49 fits into 87 1 times, leaving a remainder of 38.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 38 after subtracting 49 from 87.
Grab the next digit (7) from the dividend, add it to 38, then carry on: 387 / 49

Let's proceed to step 3:
When dividing 387 by 49, we get 7 with a remainder of 44.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
Subtract 343 from 387 to get 44.
Include the next digit (6) from the dividend after 44, then repeat: 446 / 49

Moving on to step 4:
When dividing 446 by 49, we get 9 with a remainder of 5.
Record the quotient 9 as the next digit in the result. 
Result so far: 179.0
If we take 441 away from 446, we end up with 5.
Append the next digit (8) from the dividend to 5 and continue with: 58 / 49

Let's proceed to step 5:
49 goes into 58 1 times with a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 1791.0
The remainder is 9 after subtracting 49 from 58.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 49

On to step 6:
49 goes into 91 1 times with a remainder of 42.
Record the quotient 1 as the next digit in the result. 
Result so far: 17911.0
The remainder is 42 after subtracting 49 from 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 7:
If we divide 420 by 49, we get 8 and a remainder of 28.
Record the quotient 8 as the next digit in the result. 
Result so far: 17911.8
If we take 392 away from 420, we end up 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 8:
49 can be fit into 280 5 times, resulting in a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 17911.85
Deduct 245 from 280 and we're left 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.

Going ahead to step 9:
350 divided by 49 is 7 with a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 17911.857
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.

Going ahead to step 10:
49 can be fit into 70 1 times, resulting in a remainder of 21.
Record the quotient 1 as the next digit in the result. 
Result so far: 17911.8571
The remainder is 21 after subtracting 49 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 11:
49 goes into 210 4 times with a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 17911.85714
Subtract 196 from 210 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 12:
49 can be fit into 140 2 times, resulting in a remainder of 42.
Write down 2 as next digit of the result. 
Result so far: 17911.857142
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 goes into 420 8 times with a remainder of 28.
Put 8 as the next digit of the answer. 
Result so far: 17911.8571428
If we take 392 away from 420, we end up 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:
When dividing 280 by 49, we get 5 with a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 17911.85714285
If we subtract 245 from 280, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The final outcome is 17911.85714285, with a leftover of 3.5e-08.
