251300 divided by 79 
The aim is to understand the frequency of 79 in 251300.

Step 1:
79 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 79

Step 2:
If we divide 25 by 79, we get 0 and a remainder of 25.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 25 after subtracting 0 from 25.
Grab the next digit (1) from the dividend, add it to 25, then carry on: 251 / 79

Step 3:
The number 79 fits into 251 3 times, leaving a remainder of 14.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 237 from 251 to get 14.
Include the next digit (3) from the dividend after 14, then repeat: 143 / 79

Let's proceed to step 4:
79 can be fit into 143 1 times, resulting in a remainder of 64.
Put 1 as the next digit of the answer. 
Result so far: 31.0
If we subtract 79 from 143, we get 64.
Bring next digit (0) of the dividend behind the 64 and repeat the process: 640 / 79

On to step 5:
When dividing 640 by 79, we get 8 with a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 318.0
The remainder is 8 after subtracting 632 from 640.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 79

Step 6:
If we divide 80 by 79, we get 1 and a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 3181.0
Subtract 79 from 80 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
79 can be fit into 10 0 times, resulting in a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 3181.0
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
79 goes into 100 1 times with a remainder of 21.
The next digit of our result is 1. 
Result so far: 3181.01
If we subtract 79 from 100, 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.

Moving on to step 9:
79 can be fit into 210 2 times, resulting in a remainder of 52.
Put 2 as the next digit of the answer. 
Result so far: 3181.012
If we take 158 away from 210, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 10:
When dividing 520 by 79, we get 6 with a remainder of 46.
Put 6 as the next digit of the answer. 
Result so far: 3181.0126
If we take 474 away from 520, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 11:
The number 79 fits into 460 5 times, leaving a remainder of 65.
Put 5 as the next digit of the answer. 
Result so far: 3181.01265
Deduct 395 from 460 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Advancing to step 12:
79 goes into 650 8 times with a remainder of 18.
The next digit of our result is 8. 
Result so far: 3181.012658
If we subtract 632 from 650, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 13:
If we divide 180 by 79, we get 2 and a remainder of 22.
Record the quotient 2 as the next digit in the result. 
Result so far: 3181.0126582
Subtract 158 from 180 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 14:
220 divided by 79 is 2 with a remainder of 62.
Write down 2 as next digit of the result. 
Result so far: 3181.01265822
If we take 158 away from 220, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

The final result is 3181.01265822 with a remainder of 6.2e-08.
