We divide 420155 by 63
The aim is to understand the frequency of 63 in 420155.

Moving on to step 1:
4 divided by 63 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 63

On to step 2:
42 divided by 63 is 0 with a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Bring next digit (0) of the dividend behind the 42 and repeat the process: 420 / 63

Advancing to step 3:
The number 63 fits into 420 6 times, leaving a remainder of 42.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we subtract 378 from 420, we get 42.
Take the next digit (1) from the dividend and append it to 42, then repeat: 421 / 63

Moving on to step 4:
If we divide 421 by 63, we get 6 and a remainder of 43.
Use 6 as the next digit of our solution. 
Result so far: 66.0
Subtract 378 from 421 to get 43.
Grab the next digit (5) from the dividend, add it to 43, then carry on: 435 / 63

Step 5:
63 goes into 435 6 times with a remainder of 57.
Use 6 as the next digit of our solution. 
Result so far: 666.0
Subtracting 378 from 435 leaves us with 57.
Append the next digit (5) from the dividend to 57 and continue with: 575 / 63

On to step 6:
63 can be fit into 575 9 times, resulting in a remainder of 8.
Record the quotient 9 as the next digit in the result. 
Result so far: 6669.0
Deduct 567 from 575 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 7:
63 goes into 80 1 times with a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 6669.1
The remainder is 17 after subtracting 63 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 8:
If we divide 170 by 63, we get 2 and a remainder of 44.
Use 2 as the next digit of our solution. 
Result so far: 6669.12
The remainder is 44 after subtracting 126 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 9:
63 can be fit into 440 6 times, resulting in a remainder of 62.
Put 6 as the next digit of the answer. 
Result so far: 6669.126
If we subtract 378 from 440, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 10:
620 divided by 63 is 9 with a remainder of 53.
The number 9 becomes the next digit in our result. 
Result so far: 6669.1269
Deduct 567 from 620 and we're left with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Let's proceed to step 11:
The number 63 fits into 530 8 times, leaving a remainder of 26.
Use 8 as the next digit of our solution. 
Result so far: 6669.12698
If we take 504 away from 530, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 12:
63 can be fit into 260 4 times, resulting in a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 6669.126984
Subtract 252 from 260 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 13:
63 goes into 80 1 times with a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 6669.1269841
The remainder is 17 after subtracting 63 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 14:
The number 63 fits into 170 2 times, leaving a remainder of 44.
Put 2 as the next digit of the answer. 
Result so far: 6669.12698412
The remainder is 44 after subtracting 126 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

The final outcome is 6669.12698412, with a leftover of 4.4e-08.
