49346986 divided by 251 
The aim is to understand the frequency of 251 in 49346986.

On to step 1:
4 divided by 251 is 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 251

Going ahead to step 2:
251 goes into 49 0 times with a remainder of 49.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 49 leaves us with 49.
Bring next digit (3) of the dividend behind the 49 and repeat the process: 493 / 251

Step 3:
251 can be fit into 493 1 times, resulting in a remainder of 242.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 251 from 493 and we're left with 242.
Append the next digit (4) from the dividend to 242 and continue with: 2424 / 251

Moving on to step 4:
When dividing 2424 by 251, we get 9 with a remainder of 165.
Put 9 as the next digit of the answer. 
Result so far: 19.0
Subtracting 2259 from 2424 leaves us with 165.
Take the next digit (6) from the dividend and append it to 165, then repeat: 1656 / 251

Advancing to step 5:
The number 251 fits into 1656 6 times, leaving a remainder of 150.
The next digit of our result is 6. 
Result so far: 196.0
If we subtract 1506 from 1656, we get 150.
Include the next digit (9) from the dividend after 150, then repeat: 1509 / 251

On to step 6:
If we divide 1509 by 251, we get 6 and a remainder of 3.
Put 6 as the next digit of the answer. 
Result so far: 1966.0
Subtracting 1506 from 1509 leaves us with 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 251

Going ahead to step 7:
The number 251 fits into 38 0 times, leaving a remainder of 38.
Record the quotient 0 as the next digit in the result. 
Result so far: 19660.0
Deduct 0 from 38 and we're left with 38.
Append the next digit (6) from the dividend to 38 and continue with: 386 / 251

Advancing to step 8:
If we divide 386 by 251, we get 1 and a remainder of 135.
The number 1 becomes the next digit in our result. 
Result so far: 196601.0
If we subtract 251 from 386, we get 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Let's proceed to step 9:
When dividing 1350 by 251, we get 5 with a remainder of 95.
Record the quotient 5 as the next digit in the result. 
Result so far: 196601.5
If we take 1255 away from 1350, we end up with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Moving on to step 10:
251 can be fit into 950 3 times, resulting in a remainder of 197.
Record the quotient 3 as the next digit in the result. 
Result so far: 196601.53
Deduct 753 from 950 and we're left with 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

On to step 11:
251 goes into 1970 7 times with a remainder of 213.
Put 7 as the next digit of the answer. 
Result so far: 196601.537
The remainder is 213 after subtracting 1757 from 1970.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2130, and continue the process.

Let's proceed to step 12:
251 can be fit into 2130 8 times, resulting in a remainder of 122.
Put 8 as the next digit of the answer. 
Result so far: 196601.5378
Deduct 2008 from 2130 and we're left with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Moving on to step 13:
251 goes into 1220 4 times with a remainder of 216.
The number 4 becomes the next digit in our result. 
Result so far: 196601.53784
If we take 1004 away from 1220, we end up with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Let's proceed to step 14:
251 goes into 2160 8 times with a remainder of 152.
Write down 8 as next digit of the result. 
Result so far: 196601.537848
If we take 2008 away from 2160, we end up with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Moving on to step 15:
When dividing 1520 by 251, we get 6 with a remainder of 14.
The next digit of our result is 6. 
Result so far: 196601.5378486
If we take 1506 away from 1520, we end up 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.

Going ahead to step 16:
The number 251 fits into 140 0 times, leaving a remainder of 140.
Write down 0 as next digit of the result. 
Result so far: 196601.5378486
Deduct 0 from 140 and we're left with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

In conclusion, the division gives 196601.5378486 with a balance of 1.4e-07.
