We look at the division of 63778544 by 531 
The aim is to understand the frequency of 531 in 63778544.

Going ahead to step 1:
When dividing 6 by 531, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 531

Advancing to step 2:
63 divided by 531 is 0 with a remainder of 63.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 63 to get 63.
Fetch the next digit (7) from the dividend, attach it to 63 and continue: 637 / 531

Moving on to step 3:
When dividing 637 by 531, we get 1 with a remainder of 106.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 531 from 637 leaves us with 106.
Append the next digit (7) from the dividend to 106 and continue with: 1067 / 531

On to step 4:
The number 531 fits into 1067 2 times, leaving a remainder of 5.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtract 1062 from 1067 to get 5.
Grab the next digit (8) from the dividend, add it to 5, then carry on: 58 / 531

Step 5:
531 goes into 58 0 times with a remainder of 58.
The next digit of our result is 0. 
Result so far: 120.0
Subtract 0 from 58 to get 58.
Include the next digit (5) from the dividend after 58, then repeat: 585 / 531

Advancing to step 6:
If we divide 585 by 531, we get 1 and a remainder of 54.
Put 1 as the next digit of the answer. 
Result so far: 1201.0
Subtract 531 from 585 to get 54.
Include the next digit (4) from the dividend after 54, then repeat: 544 / 531

Advancing to step 7:
The number 531 fits into 544 1 times, leaving a remainder of 13.
Write down 1 as next digit of the result. 
Result so far: 12011.0
Subtracting 531 from 544 leaves us with 13.
Take the next digit (4) from the dividend and append it to 13, then repeat: 134 / 531

Moving on to step 8:
134 divided by 531 is 0 with a remainder of 134.
Record the quotient 0 as the next digit in the result. 
Result so far: 120110.0
Deduct 0 from 134 and we're left with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Let's proceed to step 9:
The number 531 fits into 1340 2 times, leaving a remainder of 278.
The next digit of our result is 2. 
Result so far: 120110.2
Deduct 1062 from 1340 and we're left with 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

Moving on to step 10:
531 goes into 2780 5 times with a remainder of 125.
Record the quotient 5 as the next digit in the result. 
Result so far: 120110.25
Deduct 2655 from 2780 and we're left with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

On to step 11:
531 can be fit into 1250 2 times, resulting in a remainder of 188.
Put 2 as the next digit of the answer. 
Result so far: 120110.252
Subtract 1062 from 1250 to get 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Step 12:
1880 divided by 531 is 3 with a remainder of 287.
Record the quotient 3 as the next digit in the result. 
Result so far: 120110.2523
If we take 1593 away from 1880, we end up with 287.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2870, and continue the process.

Let's proceed to step 13:
The number 531 fits into 2870 5 times, leaving a remainder of 215.
Use 5 as the next digit of our solution. 
Result so far: 120110.25235
If we subtract 2655 from 2870, we get 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Advancing to step 14:
531 goes into 2150 4 times with a remainder of 26.
Put 4 as the next digit of the answer. 
Result so far: 120110.252354
Subtracting 2124 from 2150 leaves us 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.

Advancing to step 15:
260 divided by 531 is 0 with a remainder of 260.
The next digit of our result is 0. 
Result so far: 120110.252354
If we subtract 0 from 260, we get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Let's proceed to step 16:
531 can be fit into 2600 4 times, resulting in a remainder of 476.
The number 4 becomes the next digit in our result. 
Result so far: 120110.25235404
Deduct 2124 from 2600 and we're left with 476.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

In conclusion, the division gives 120110.25235404 with a balance of 4.76e-07.
