We're dividing 63461588 by 813 
The aim is to understand the frequency of 813 in 63461588.

Step 1:
813 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 813

On to step 2:
813 goes into 63 0 times with a remainder of 63.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 63 leaves us with 63.
Grab the next digit (4) from the dividend, add it to 63, then carry on: 634 / 813

Let's proceed to step 3:
634 divided by 813 is 0 with a remainder of 634.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 634 and we're left with 634.
Take the next digit (6) from the dividend and append it to 634, then repeat: 6346 / 813

Advancing to step 4:
813 can be fit into 6346 7 times, resulting in a remainder of 655.
The next digit of our result is 7. 
Result so far: 7.0
Subtract 5691 from 6346 to get 655.
Grab the next digit (1) from the dividend, add it to 655, then carry on: 6551 / 813

Going ahead to step 5:
If we divide 6551 by 813, we get 8 and a remainder of 47.
Put 8 as the next digit of the answer. 
Result so far: 78.0
Deduct 6504 from 6551 and we're left with 47.
Grab the next digit (5) from the dividend, add it to 47, then carry on: 475 / 813

Advancing to step 6:
813 can be fit into 475 0 times, resulting in a remainder of 475.
Record the quotient 0 as the next digit in the result. 
Result so far: 780.0
If we take 0 away from 475, we end up with 475.
Take the next digit (8) from the dividend and append it to 475, then repeat: 4758 / 813

Let's proceed to step 7:
813 goes into 4758 5 times with a remainder of 693.
Record the quotient 5 as the next digit in the result. 
Result so far: 7805.0
Deduct 4065 from 4758 and we're left with 693.
Take the next digit (8) from the dividend and append it to 693, then repeat: 6938 / 813

Advancing to step 8:
The number 813 fits into 6938 8 times, leaving a remainder of 434.
Put 8 as the next digit of the answer. 
Result so far: 78058.0
Deduct 6504 from 6938 and we're left with 434.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4340, and continue the process.

Let's proceed to step 9:
If we divide 4340 by 813, we get 5 and a remainder of 275.
Record the quotient 5 as the next digit in the result. 
Result so far: 78058.5
Deduct 4065 from 4340 and we're left with 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

On to step 10:
The number 813 fits into 2750 3 times, leaving a remainder of 311.
Record the quotient 3 as the next digit in the result. 
Result so far: 78058.53
Deduct 2439 from 2750 and we're left with 311.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3110, and continue the process.

Step 11:
When dividing 3110 by 813, we get 3 with a remainder of 671.
Use 3 as the next digit of our solution. 
Result so far: 78058.533
The remainder is 671 after subtracting 2439 from 3110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6710, and continue the process.

The final outcome is 78058.533, with a leftover of 0.0671.
