We look at the division of 89045382 by 251 
The aim is to understand the frequency of 251 in 89045382.

On to step 1:
If we divide 8 by 251, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (9) from the dividend to 8 and continue with: 89 / 251

Advancing to step 2:
251 can be fit into 89 0 times, resulting in a remainder of 89.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 89 leaves us with 89.
Include the next digit (0) from the dividend after 89, then repeat: 890 / 251

Advancing to step 3:
251 can be fit into 890 3 times, resulting in a remainder of 137.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 753 away from 890, we end up with 137.
Append the next digit (4) from the dividend to 137 and continue with: 1374 / 251

Let's proceed to step 4:
251 goes into 1374 5 times with a remainder of 119.
Write down 5 as next digit of the result. 
Result so far: 35.0
Subtract 1255 from 1374 to get 119.
Fetch the next digit (5) from the dividend, attach it to 119 and continue: 1195 / 251

Moving on to step 5:
251 can be fit into 1195 4 times, resulting in a remainder of 191.
The next digit of our result is 4. 
Result so far: 354.0
If we take 1004 away from 1195, we end up with 191.
Grab the next digit (3) from the dividend, add it to 191, then carry on: 1913 / 251

Step 6:
The number 251 fits into 1913 7 times, leaving a remainder of 156.
Write down 7 as next digit of the result. 
Result so far: 3547.0
Subtracting 1757 from 1913 leaves us with 156.
Bring next digit (8) of the dividend behind the 156 and repeat the process: 1568 / 251

On to step 7:
251 goes into 1568 6 times with a remainder of 62.
Put 6 as the next digit of the answer. 
Result so far: 35476.0
Deduct 1506 from 1568 and we're left with 62.
Append the next digit (2) from the dividend to 62 and continue with: 622 / 251

Let's proceed to step 8:
622 divided by 251 is 2 with a remainder of 120.
Put 2 as the next digit of the answer. 
Result so far: 354762.0
If we take 502 away from 622, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Let's proceed to step 9:
251 can be fit into 1200 4 times, resulting in a remainder of 196.
The next digit of our result is 4. 
Result so far: 354762.4
Deduct 1004 from 1200 and we're left with 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Moving on to step 10:
1960 divided by 251 is 7 with a remainder of 203.
Use 7 as the next digit of our solution. 
Result so far: 354762.47
Subtract 1757 from 1960 to get 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

Moving on to step 11:
251 goes into 2030 8 times with a remainder of 22.
Use 8 as the next digit of our solution. 
Result so far: 354762.478
The remainder is 22 after subtracting 2008 from 2030.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 12:
220 divided by 251 is 0 with a remainder of 220.
The next digit of our result is 0. 
Result so far: 354762.478
If we subtract 0 from 220, we get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Advancing to step 13:
251 can be fit into 2200 8 times, resulting in a remainder of 192.
The number 8 becomes the next digit in our result. 
Result so far: 354762.47808
Deduct 2008 from 2200 and we're left with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Moving on to step 14:
When dividing 1920 by 251, we get 7 with a remainder of 163.
Put 7 as the next digit of the answer. 
Result so far: 354762.478087
If we take 1757 away from 1920, we end up with 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

Advancing to step 15:
When dividing 1630 by 251, we get 6 with a remainder of 124.
The next digit of our result is 6. 
Result so far: 354762.4780876
Deduct 1506 from 1630 and we're left with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Going ahead to step 16:
251 can be fit into 1240 4 times, resulting in a remainder of 236.
Record the quotient 4 as the next digit in the result. 
Result so far: 354762.47808764
If we subtract 1004 from 1240, we get 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Our division results in 354762.47808764 with a remaining 2.36e-07.
