We're dividing 373121 by 63 
The aim is to understand the frequency of 63 in 373121.

Step 1:
63 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (7) from the dividend, attach it to 3 and continue: 37 / 63

Let's proceed to step 2:
37 divided by 63 is 0 with a remainder of 37.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 37, we get 37.
Grab the next digit (3) from the dividend, add it to 37, then carry on: 373 / 63

Step 3:
The number 63 fits into 373 5 times, leaving a remainder of 58.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Deduct 315 from 373 and we're left with 58.
Append the next digit (1) from the dividend to 58 and continue with: 581 / 63

Moving on to step 4:
581 divided by 63 is 9 with a remainder of 14.
Write down 9 as next digit of the result. 
Result so far: 59.0
Deduct 567 from 581 and we're left with 14.
Grab the next digit (2) from the dividend, add it to 14, then carry on: 142 / 63

Going ahead to step 5:
63 goes into 142 2 times with a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 592.0
Subtract 126 from 142 to get 16.
Bring next digit (1) of the dividend behind the 16 and repeat the process: 161 / 63

Let's proceed to step 6:
If we divide 161 by 63, we get 2 and a remainder of 35.
Use 2 as the next digit of our solution. 
Result so far: 5922.0
The remainder is 35 after subtracting 126 from 161.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 7:
If we divide 350 by 63, we get 5 and a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 5922.5
Deduct 315 from 350 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 8:
63 can be fit into 350 5 times, resulting in a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 5922.55
Subtract 315 from 350 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

In conclusion, the division gives 5922.55 with a balance of 0.035.
