We divide 51191251 by 101
The aim is to understand the frequency of 101 in 51191251.

Advancing to step 1:
The number 101 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 101

Let's proceed to step 2:
If we divide 51 by 101, we get 0 and a remainder of 51.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 51, we end up with 51.
Append the next digit (1) from the dividend to 51 and continue with: 511 / 101

Moving on to step 3:
If we divide 511 by 101, we get 5 and a remainder of 6.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Deduct 505 from 511 and we're left with 6.
Take the next digit (9) from the dividend and append it to 6, then repeat: 69 / 101

Let's proceed to step 4:
101 goes into 69 0 times with a remainder of 69.
Use 0 as the next digit of our solution. 
Result so far: 50.0
The remainder is 69 after subtracting 0 from 69.
Fetch the next digit (1) from the dividend, attach it to 69 and continue: 691 / 101

Advancing to step 5:
When dividing 691 by 101, we get 6 with a remainder of 85.
The number 6 becomes the next digit in our result. 
Result so far: 506.0
Subtracting 606 from 691 leaves us with 85.
Fetch the next digit (2) from the dividend, attach it to 85 and continue: 852 / 101

Let's proceed to step 6:
When dividing 852 by 101, we get 8 with a remainder of 44.
The number 8 becomes the next digit in our result. 
Result so far: 5068.0
Subtract 808 from 852 to get 44.
Include the next digit (5) from the dividend after 44, then repeat: 445 / 101

Let's proceed to step 7:
101 goes into 445 4 times with a remainder of 41.
Put 4 as the next digit of the answer. 
Result so far: 50684.0
If we subtract 404 from 445, we get 41.
Fetch the next digit (1) from the dividend, attach it to 41 and continue: 411 / 101

On to step 8:
The number 101 fits into 411 4 times, leaving a remainder of 7.
The next digit of our result is 4. 
Result so far: 506844.0
The remainder is 7 after subtracting 404 from 411.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 9:
101 goes into 70 0 times with a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 506844.0
Subtracting 0 from 70 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 10:
700 divided by 101 is 6 with a remainder of 94.
Put 6 as the next digit of the answer. 
Result so far: 506844.06
If we take 606 away from 700, we end up with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Moving on to step 11:
940 divided by 101 is 9 with a remainder of 31.
Put 9 as the next digit of the answer. 
Result so far: 506844.069
The remainder is 31 after subtracting 909 from 940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 12:
The number 101 fits into 310 3 times, leaving a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 506844.0693
The remainder is 7 after subtracting 303 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 13:
101 goes into 70 0 times with a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 506844.0693
If we subtract 0 from 70, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 14:
700 divided by 101 is 6 with a remainder of 94.
Use 6 as the next digit of our solution. 
Result so far: 506844.069306
Subtracting 606 from 700 leaves us with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Going ahead to step 15:
When dividing 940 by 101, we get 9 with a remainder of 31.
Put 9 as the next digit of the answer. 
Result so far: 506844.0693069
Deduct 909 from 940 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 16:
310 divided by 101 is 3 with a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 506844.06930693
If we subtract 303 from 310, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

In conclusion, the division gives 506844.06930693 with a balance of 7e-09.
