790150 ÷ 49 
The aim is to understand the frequency of 49 in 790150.

Advancing to step 1:
When dividing 7 by 49, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 49

Moving on to step 2:
When dividing 79 by 49, we get 1 with a remainder of 30.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 49 from 79, we get 30.
Take the next digit (0) from the dividend and append it to 30, then repeat: 300 / 49

Advancing to step 3:
49 goes into 300 6 times with a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 16.0
Deduct 294 from 300 and we're left with 6.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 49

Going ahead to step 4:
If we divide 61 by 49, we get 1 and a remainder of 12.
The next digit of our result is 1. 
Result so far: 161.0
The remainder is 12 after subtracting 49 from 61.
Bring next digit (5) of the dividend behind the 12 and repeat the process: 125 / 49

Step 5:
If we divide 125 by 49, we get 2 and a remainder of 27.
Use 2 as the next digit of our solution. 
Result so far: 1612.0
Deduct 98 from 125 and we're left with 27.
Bring next digit (0) of the dividend behind the 27 and repeat the process: 270 / 49

Step 6:
49 goes into 270 5 times with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 16125.0
If we subtract 245 from 270, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 7:
250 divided by 49 is 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 16125.5
Subtract 245 from 250 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 8:
When dividing 50 by 49, we get 1 with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 16125.51
Subtracting 49 from 50 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 9:
49 goes into 10 0 times with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 16125.51
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 10:
49 can be fit into 100 2 times, resulting in a remainder of 2.
The next digit of our result is 2. 
Result so far: 16125.5102
Deduct 98 from 100 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 11:
If we divide 20 by 49, we get 0 and a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 16125.5102
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 12:
200 divided by 49 is 4 with a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 16125.510204
If we take 196 away from 200, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 13:
49 goes into 40 0 times with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 16125.510204
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 14:
The number 49 fits into 400 8 times, leaving a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 16125.51020408
If we take 392 away from 400, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

After the division, we end up with 16125.51020408 and a remainder of 8e-09.
