Let's divide 25310790 by 207
The aim is to understand the frequency of 207 in 25310790.

On to step 1:
The number 207 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 207

On to step 2:
When dividing 25 by 207, we get 0 with a remainder of 25.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 25 leaves us with 25.
Include the next digit (3) from the dividend after 25, then repeat: 253 / 207

Moving on to step 3:
When dividing 253 by 207, we get 1 with a remainder of 46.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 207 from 253, we get 46.
Take the next digit (1) from the dividend and append it to 46, then repeat: 461 / 207

Moving on to step 4:
If we divide 461 by 207, we get 2 and a remainder of 47.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we subtract 414 from 461, we get 47.
Bring next digit (0) of the dividend behind the 47 and repeat the process: 470 / 207

Going ahead to step 5:
207 can be fit into 470 2 times, resulting in a remainder of 56.
The next digit of our result is 2. 
Result so far: 122.0
Deduct 414 from 470 and we're left with 56.
Grab the next digit (7) from the dividend, add it to 56, then carry on: 567 / 207

Moving on to step 6:
The number 207 fits into 567 2 times, leaving a remainder of 153.
The next digit of our result is 2. 
Result so far: 1222.0
If we subtract 414 from 567, we get 153.
Take the next digit (9) from the dividend and append it to 153, then repeat: 1539 / 207

On to step 7:
When dividing 1539 by 207, we get 7 with a remainder of 90.
Record the quotient 7 as the next digit in the result. 
Result so far: 12227.0
Subtract 1449 from 1539 to get 90.
Append the next digit (0) from the dividend to 90 and continue with: 900 / 207

Let's proceed to step 8:
When dividing 900 by 207, we get 4 with a remainder of 72.
Use 4 as the next digit of our solution. 
Result so far: 122274.0
Deduct 828 from 900 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 9:
207 goes into 720 3 times with a remainder of 99.
The number 3 becomes the next digit in our result. 
Result so far: 122274.3
Subtract 621 from 720 to get 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Advancing to step 10:
If we divide 990 by 207, we get 4 and a remainder of 162.
Record the quotient 4 as the next digit in the result. 
Result so far: 122274.34
Subtract 828 from 990 to get 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Moving on to step 11:
207 can be fit into 1620 7 times, resulting in a remainder of 171.
Use 7 as the next digit of our solution. 
Result so far: 122274.347
Deduct 1449 from 1620 and we're left with 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

On to step 12:
The number 207 fits into 1710 8 times, leaving a remainder of 54.
Put 8 as the next digit of the answer. 
Result so far: 122274.3478
Deduct 1656 from 1710 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 13:
207 goes into 540 2 times with a remainder of 126.
Write down 2 as next digit of the result. 
Result so far: 122274.34782
If we take 414 away from 540, we end up with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Advancing to step 14:
If we divide 1260 by 207, we get 6 and a remainder of 18.
Write down 6 as next digit of the result. 
Result so far: 122274.347826
The remainder is 18 after subtracting 1242 from 1260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 15:
180 divided by 207 is 0 with a remainder of 180.
The next digit of our result is 0. 
Result so far: 122274.347826
Subtracting 0 from 180 leaves us with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Advancing to step 16:
207 goes into 1800 8 times with a remainder of 144.
The next digit of our result is 8. 
Result so far: 122274.34782608
Subtract 1656 from 1800 to get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

After the division, we end up with 122274.34782608 and a remainder of 1.44e-07.
