We're dividing 19799911 by 951 
The aim is to understand the frequency of 951 in 19799911.

Step 1:
If we divide 1 by 951, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 951

Step 2:
If we divide 19 by 951, we get 0 and a remainder of 19.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 19, we get 19.
Take the next digit (7) from the dividend and append it to 19, then repeat: 197 / 951

Moving on to step 3:
951 can be fit into 197 0 times, resulting in a remainder of 197.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 197 to get 197.
Take the next digit (9) from the dividend and append it to 197, then repeat: 1979 / 951

Let's proceed to step 4:
951 can be fit into 1979 2 times, resulting in a remainder of 77.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 1902 from 1979, we get 77.
Take the next digit (9) from the dividend and append it to 77, then repeat: 779 / 951

Let's proceed to step 5:
The number 951 fits into 779 0 times, leaving a remainder of 779.
Use 0 as the next digit of our solution. 
Result so far: 20.0
If we take 0 away from 779, we end up with 779.
Take the next digit (9) from the dividend and append it to 779, then repeat: 7799 / 951

Advancing to step 6:
951 goes into 7799 8 times with a remainder of 191.
Record the quotient 8 as the next digit in the result. 
Result so far: 208.0
Subtract 7608 from 7799 to get 191.
Include the next digit (1) from the dividend after 191, then repeat: 1911 / 951

Going ahead to step 7:
When dividing 1911 by 951, we get 2 with a remainder of 9.
Put 2 as the next digit of the answer. 
Result so far: 2082.0
Subtract 1902 from 1911 to get 9.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 951

Advancing to step 8:
If we divide 91 by 951, we get 0 and a remainder of 91.
Use 0 as the next digit of our solution. 
Result so far: 20820.0
If we take 0 away from 91, we end up with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Advancing to step 9:
The number 951 fits into 910 0 times, leaving a remainder of 910.
Use 0 as the next digit of our solution. 
Result so far: 20820.0
Subtracting 0 from 910 leaves us with 910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9100, and continue the process.

Going ahead to step 10:
9100 divided by 951 is 9 with a remainder of 541.
The next digit of our result is 9. 
Result so far: 20820.09
Subtract 8559 from 9100 to get 541.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5410, and continue the process.

Let's proceed to step 11:
When dividing 5410 by 951, we get 5 with a remainder of 655.
Write down 5 as next digit of the result. 
Result so far: 20820.095
If we subtract 4755 from 5410, we get 655.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6550, and continue the process.

On to step 12:
The number 951 fits into 6550 6 times, leaving a remainder of 844.
Put 6 as the next digit of the answer. 
Result so far: 20820.0956
Deduct 5706 from 6550 and we're left with 844.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8440, and continue the process.

Advancing to step 13:
If we divide 8440 by 951, we get 8 and a remainder of 832.
The number 8 becomes the next digit in our result. 
Result so far: 20820.09568
If we take 7608 away from 8440, we end up with 832.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8320, and continue the process.

Let's proceed to step 14:
951 goes into 8320 8 times with a remainder of 712.
Put 8 as the next digit of the answer. 
Result so far: 20820.095688
Subtract 7608 from 8320 to get 712.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7120, and continue the process.

The final result is 20820.095688 with a remainder of 7.12e-05.
