63415869 divided by 651 
The aim is to understand the frequency of 651 in 63415869.

Let's proceed to step 1:
651 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 651

Step 2:
651 can be fit into 63 0 times, resulting in a remainder of 63.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 63, we get 63.
Fetch the next digit (4) from the dividend, attach it to 63 and continue: 634 / 651

Advancing to step 3:
634 divided by 651 is 0 with a remainder of 634.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 634 to get 634.
Include the next digit (1) from the dividend after 634, then repeat: 6341 / 651

Let's proceed to step 4:
The number 651 fits into 6341 9 times, leaving a remainder of 482.
Write down 9 as next digit of the result. 
Result so far: 9.0
The remainder is 482 after subtracting 5859 from 6341.
Bring next digit (5) of the dividend behind the 482 and repeat the process: 4825 / 651

On to step 5:
651 can be fit into 4825 7 times, resulting in a remainder of 268.
Use 7 as the next digit of our solution. 
Result so far: 97.0
Deduct 4557 from 4825 and we're left with 268.
Take the next digit (8) from the dividend and append it to 268, then repeat: 2688 / 651

Moving on to step 6:
If we divide 2688 by 651, we get 4 and a remainder of 84.
Write down 4 as next digit of the result. 
Result so far: 974.0
If we subtract 2604 from 2688, we get 84.
Grab the next digit (6) from the dividend, add it to 84, then carry on: 846 / 651

Going ahead to step 7:
651 goes into 846 1 times with a remainder of 195.
Write down 1 as next digit of the result. 
Result so far: 9741.0
The remainder is 195 after subtracting 651 from 846.
Grab the next digit (9) from the dividend, add it to 195, then carry on: 1959 / 651

On to step 8:
If we divide 1959 by 651, we get 3 and a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 97413.0
Subtracting 1953 from 1959 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 9:
651 goes into 60 0 times with a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 97413.0
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 10:
651 goes into 600 0 times with a remainder of 600.
Put 0 as the next digit of the answer. 
Result so far: 97413.0
If we subtract 0 from 600, we get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Our division results in 97413.0 with a remaining 0.6.
