We look at the division of 70376374 by 251 
The aim is to understand the frequency of 251 in 70376374.

Moving on to step 1:
7 divided by 251 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (0) from the dividend to 7 and continue with: 70 / 251

Advancing to step 2:
If we divide 70 by 251, we get 0 and a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 70 after subtracting 0 from 70.
Fetch the next digit (3) from the dividend, attach it to 70 and continue: 703 / 251

Going ahead to step 3:
251 can be fit into 703 2 times, resulting in a remainder of 201.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 502 from 703, we get 201.
Grab the next digit (7) from the dividend, add it to 201, then carry on: 2017 / 251

Going ahead to step 4:
251 goes into 2017 8 times with a remainder of 9.
Write down 8 as next digit of the result. 
Result so far: 28.0
Subtract 2008 from 2017 to get 9.
Bring next digit (6) of the dividend behind the 9 and repeat the process: 96 / 251

Moving on to step 5:
The number 251 fits into 96 0 times, leaving a remainder of 96.
Write down 0 as next digit of the result. 
Result so far: 280.0
Subtracting 0 from 96 leaves us with 96.
Grab the next digit (3) from the dividend, add it to 96, then carry on: 963 / 251

Going ahead to step 6:
251 can be fit into 963 3 times, resulting in a remainder of 210.
Put 3 as the next digit of the answer. 
Result so far: 2803.0
Subtract 753 from 963 to get 210.
Grab the next digit (7) from the dividend, add it to 210, then carry on: 2107 / 251

Advancing to step 7:
The number 251 fits into 2107 8 times, leaving a remainder of 99.
The number 8 becomes the next digit in our result. 
Result so far: 28038.0
If we take 2008 away from 2107, we end up with 99.
Include the next digit (4) from the dividend after 99, then repeat: 994 / 251

Moving on to step 8:
251 can be fit into 994 3 times, resulting in a remainder of 241.
Use 3 as the next digit of our solution. 
Result so far: 280383.0
Deduct 753 from 994 and we're left with 241.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2410, and continue the process.

Advancing to step 9:
251 goes into 2410 9 times with a remainder of 151.
The number 9 becomes the next digit in our result. 
Result so far: 280383.9
Deduct 2259 from 2410 and we're left with 151.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

Going ahead to step 10:
The number 251 fits into 1510 6 times, leaving a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 280383.96
If we take 1506 away from 1510, 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.

Let's proceed to step 11:
When dividing 40 by 251, we get 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 280383.96
Subtracting 0 from 40 leaves us 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.

Moving on to step 12:
251 goes into 400 1 times with a remainder of 149.
Write down 1 as next digit of the result. 
Result so far: 280383.9601
If we take 251 away from 400, we end up with 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

Step 13:
When dividing 1490 by 251, we get 5 with a remainder of 235.
Put 5 as the next digit of the answer. 
Result so far: 280383.96015
Deduct 1255 from 1490 and we're left with 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Advancing to step 14:
251 can be fit into 2350 9 times, resulting in a remainder of 91.
Write down 9 as next digit of the result. 
Result so far: 280383.960159
If we subtract 2259 from 2350, we get 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Let's proceed to step 15:
When dividing 910 by 251, we get 3 with a remainder of 157.
Put 3 as the next digit of the answer. 
Result so far: 280383.9601593
The remainder is 157 after subtracting 753 from 910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Advancing to step 16:
When dividing 1570 by 251, we get 6 with a remainder of 64.
The number 6 becomes the next digit in our result. 
Result so far: 280383.96015936
The remainder is 64 after subtracting 1506 from 1570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The final result is 280383.96015936 with a remainder of 6.4e-08.
