421473 divided by 63 
The aim is to understand the frequency of 63 in 421473.

Let's proceed to step 1:
The number 63 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 63

Let's proceed to step 2:
If we divide 42 by 63, we get 0 and a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Fetch the next digit (1) from the dividend, attach it to 42 and continue: 421 / 63

Let's proceed to step 3:
421 divided by 63 is 6 with a remainder of 43.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtract 378 from 421 to get 43.
Take the next digit (4) from the dividend and append it to 43, then repeat: 434 / 63

Advancing to step 4:
When dividing 434 by 63, we get 6 with a remainder of 56.
Use 6 as the next digit of our solution. 
Result so far: 66.0
The remainder is 56 after subtracting 378 from 434.
Fetch the next digit (7) from the dividend, attach it to 56 and continue: 567 / 63

Moving on to step 5:
63 goes into 567 9 times with a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 669.0
Subtract 567 from 567 to get 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 63

Moving on to step 6:
When dividing 3 by 63, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 6690.0
If we take 0 away from 3, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 7:
63 can be fit into 30 0 times, resulting in a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 6690.0
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 8:
The number 63 fits into 300 4 times, leaving a remainder of 48.
Record the quotient 4 as the next digit in the result. 
Result so far: 6690.04
Deduct 252 from 300 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 9:
63 can be fit into 480 7 times, resulting in a remainder of 39.
Put 7 as the next digit of the answer. 
Result so far: 6690.047
Subtract 441 from 480 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 10:
63 can be fit into 390 6 times, resulting in a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 6690.0476
Subtracting 378 from 390 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 11:
63 goes into 120 1 times with a remainder of 57.
Record the quotient 1 as the next digit in the result. 
Result so far: 6690.04761
If we subtract 63 from 120, we get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Step 12:
63 can be fit into 570 9 times, resulting in a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 6690.047619
The remainder is 3 after subtracting 567 from 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 13:
63 can be fit into 30 0 times, resulting in a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 6690.047619
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 14:
63 can be fit into 300 4 times, resulting in a remainder of 48.
The next digit of our result is 4. 
Result so far: 6690.04761904
Deduct 252 from 300 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Our division results in 6690.04761904 with a remaining 4.8e-08.
