We divide 66887473 by 123
The aim is to understand the frequency of 123 in 66887473.

Going ahead to step 1:
The number 123 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 123

On to step 2:
When dividing 66 by 123, we get 0 with a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 66 leaves us with 66.
Take the next digit (8) from the dividend and append it to 66, then repeat: 668 / 123

On to step 3:
668 divided by 123 is 5 with a remainder of 53.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we take 615 away from 668, we end up with 53.
Fetch the next digit (8) from the dividend, attach it to 53 and continue: 538 / 123

Going ahead to step 4:
538 divided by 123 is 4 with a remainder of 46.
Record the quotient 4 as the next digit in the result. 
Result so far: 54.0
Deduct 492 from 538 and we're left with 46.
Include the next digit (7) from the dividend after 46, then repeat: 467 / 123

Step 5:
When dividing 467 by 123, we get 3 with a remainder of 98.
The number 3 becomes the next digit in our result. 
Result so far: 543.0
If we subtract 369 from 467, we get 98.
Append the next digit (4) from the dividend to 98 and continue with: 984 / 123

Advancing to step 6:
When dividing 984 by 123, we get 8 with a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 5438.0
If we subtract 984 from 984, we get 0.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 123

Advancing to step 7:
The number 123 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 54380.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (3) from the dividend, attach it to 7 and continue: 73 / 123

Let's proceed to step 8:
73 divided by 123 is 0 with a remainder of 73.
Put 0 as the next digit of the answer. 
Result so far: 543800.0
Deduct 0 from 73 and we're left with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Moving on to step 9:
If we divide 730 by 123, we get 5 and a remainder of 115.
Record the quotient 5 as the next digit in the result. 
Result so far: 543800.5
Subtracting 615 from 730 leaves us with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Moving on to step 10:
When dividing 1150 by 123, we get 9 with a remainder of 43.
The number 9 becomes the next digit in our result. 
Result so far: 543800.59
If we take 1107 away from 1150, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Moving on to step 11:
The number 123 fits into 430 3 times, leaving a remainder of 61.
Write down 3 as next digit of the result. 
Result so far: 543800.593
Subtract 369 from 430 to get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Going ahead to step 12:
The number 123 fits into 610 4 times, leaving a remainder of 118.
Use 4 as the next digit of our solution. 
Result so far: 543800.5934
Subtract 492 from 610 to get 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Moving on to step 13:
123 can be fit into 1180 9 times, resulting in a remainder of 73.
The number 9 becomes the next digit in our result. 
Result so far: 543800.59349
If we subtract 1107 from 1180, we get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

On to step 14:
When dividing 730 by 123, we get 5 with a remainder of 115.
Record the quotient 5 as the next digit in the result. 
Result so far: 543800.593495
If we take 615 away from 730, we end up with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Moving on to step 15:
123 goes into 1150 9 times with a remainder of 43.
Put 9 as the next digit of the answer. 
Result so far: 543800.5934959
If we take 1107 away from 1150, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 16:
If we divide 430 by 123, we get 3 and a remainder of 61.
Use 3 as the next digit of our solution. 
Result so far: 543800.59349593
Subtracting 369 from 430 leaves us with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Our division results in 543800.59349593 with a remaining 6.1e-08.
