We look at the division of 1651577 by 49 
The aim is to understand the frequency of 49 in 1651577.

Going ahead to step 1:
49 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 49

On to step 2:
16 divided by 49 is 0 with a remainder of 16.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 16 to get 16.
Append the next digit (5) from the dividend to 16 and continue with: 165 / 49

On to step 3:
If we divide 165 by 49, we get 3 and a remainder of 18.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 147 from 165 and we're left with 18.
Take the next digit (1) from the dividend and append it to 18, then repeat: 181 / 49

Moving on to step 4:
181 divided by 49 is 3 with a remainder of 34.
Put 3 as the next digit of the answer. 
Result so far: 33.0
If we take 147 away from 181, we end up with 34.
Append the next digit (5) from the dividend to 34 and continue with: 345 / 49

Moving on to step 5:
49 can be fit into 345 7 times, resulting in a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 337.0
If we take 343 away from 345, we end up with 2.
Grab the next digit (7) from the dividend, add it to 2, then carry on: 27 / 49

Going ahead to step 6:
27 divided by 49 is 0 with a remainder of 27.
Record the quotient 0 as the next digit in the result. 
Result so far: 3370.0
If we subtract 0 from 27, we get 27.
Append the next digit (7) from the dividend to 27 and continue with: 277 / 49

Let's proceed to step 7:
If we divide 277 by 49, we get 5 and a remainder of 32.
The number 5 becomes the next digit in our result. 
Result so far: 33705.0
If we subtract 245 from 277, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 8:
The number 49 fits into 320 6 times, leaving a remainder of 26.
The number 6 becomes the next digit in our result. 
Result so far: 33705.6
If we take 294 away from 320, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 9:
When dividing 260 by 49, we get 5 with a remainder of 15.
The next digit of our result is 5. 
Result so far: 33705.65
Subtract 245 from 260 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 10:
49 goes into 150 3 times with a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 33705.653
The remainder is 3 after subtracting 147 from 150.
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 11:
49 goes into 30 0 times with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 33705.653
If we take 0 away from 30, we end up 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 12:
49 can be fit into 300 6 times, resulting in a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 33705.65306
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 13:
60 divided by 49 is 1 with a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 33705.653061
Subtract 49 from 60 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 14:
49 can be fit into 110 2 times, resulting in a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 33705.6530612
The remainder is 12 after subtracting 98 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 15:
The number 49 fits into 120 2 times, leaving a remainder of 22.
The number 2 becomes the next digit in our result. 
Result so far: 33705.65306122
Deduct 98 from 120 and we're left 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.

The final outcome is 33705.65306122, with a leftover of 2.2e-08.
