We divide 569401 by 49
The aim is to understand the frequency of 49 in 569401.

On to step 1:
5 divided by 49 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Grab the next digit (6) from the dividend, add it to 5, then carry on: 56 / 49

On to step 2:
When dividing 56 by 49, we get 1 with a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 49 from 56 leaves us with 7.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 49

Step 3:
If we divide 79 by 49, we get 1 and a remainder of 30.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Subtracting 49 from 79 leaves us with 30.
Take the next digit (4) from the dividend and append it to 30, then repeat: 304 / 49

Step 4:
The number 49 fits into 304 6 times, leaving a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 116.0
Deduct 294 from 304 and we're left with 10.
Fetch the next digit (0) from the dividend, attach it to 10 and continue: 100 / 49

On to step 5:
49 can be fit into 100 2 times, resulting in a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 1162.0
Subtracting 98 from 100 leaves us with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 49

On to step 6:
When dividing 21 by 49, we get 0 with a remainder of 21.
The next digit of our result is 0. 
Result so far: 11620.0
If we subtract 0 from 21, 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.

On to step 7:
49 goes into 210 4 times with a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 11620.4
Subtracting 196 from 210 leaves us 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.

Advancing to step 8:
140 divided by 49 is 2 with a remainder of 42.
Put 2 as the next digit of the answer. 
Result so far: 11620.42
Subtract 98 from 140 to 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.

Advancing to step 9:
The number 49 fits into 420 8 times, leaving a remainder of 28.
Use 8 as the next digit of our solution. 
Result so far: 11620.428
Subtract 392 from 420 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 10:
The number 49 fits into 280 5 times, leaving a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 11620.4285
The remainder is 35 after subtracting 245 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 11:
49 can be fit into 350 7 times, resulting in a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 11620.42857
If we take 343 away from 350, we end up 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.

Let's proceed to step 12:
If we divide 70 by 49, we get 1 and a remainder of 21.
Put 1 as the next digit of the answer. 
Result so far: 11620.428571
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.

Going ahead to step 13:
If we divide 210 by 49, we get 4 and a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 11620.4285714
If we subtract 196 from 210, we 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.

Going ahead to step 14:
49 goes into 140 2 times with a remainder of 42.
The next digit of our result is 2. 
Result so far: 11620.42857142
The remainder is 42 after subtracting 98 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

The final result is 11620.42857142 with a remainder of 4.2e-08.
