623785 ÷ 49 
The aim is to understand the frequency of 49 in 623785.

Step 1:
49 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (2) from the dividend, add it to 6, then carry on: 62 / 49

Going ahead to step 2:
If we divide 62 by 49, we get 1 and a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 49 from 62, we get 13.
Take the next digit (3) from the dividend and append it to 13, then repeat: 133 / 49

Going ahead to step 3:
If we divide 133 by 49, we get 2 and a remainder of 35.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we take 98 away from 133, we end up with 35.
Grab the next digit (7) from the dividend, add it to 35, then carry on: 357 / 49

Going ahead to step 4:
357 divided by 49 is 7 with a remainder of 14.
Use 7 as the next digit of our solution. 
Result so far: 127.0
If we subtract 343 from 357, we get 14.
Append the next digit (8) from the dividend to 14 and continue with: 148 / 49

Let's proceed to step 5:
49 can be fit into 148 3 times, resulting in a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 1273.0
Subtract 147 from 148 to get 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 49

Let's proceed to step 6:
49 goes into 15 0 times with a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 12730.0
Deduct 0 from 15 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 7:
150 divided by 49 is 3 with a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 12730.3
Deduct 147 from 150 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 8:
The number 49 fits into 30 0 times, leaving a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 12730.3
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 9:
300 divided by 49 is 6 with a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 12730.306
If we subtract 294 from 300, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 10:
When dividing 60 by 49, we get 1 with a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 12730.3061
Deduct 49 from 60 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 11:
49 goes into 110 2 times with a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 12730.30612
If we subtract 98 from 110, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 12:
49 goes into 120 2 times with a remainder of 22.
Put 2 as the next digit of the answer. 
Result so far: 12730.306122
Subtracting 98 from 120 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

After the division, we end up with 12730.306122 and a remainder of 2.2e-06.
