We're dividing 76610876 by 663 
The aim is to understand the frequency of 663 in 76610876.

Advancing to step 1:
The number 663 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (6) from the dividend, attach it to 7 and continue: 76 / 663

Going ahead to step 2:
When dividing 76 by 663, we get 0 with a remainder of 76.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 76 after subtracting 0 from 76.
Append the next digit (6) from the dividend to 76 and continue with: 766 / 663

Let's proceed to step 3:
663 can be fit into 766 1 times, resulting in a remainder of 103.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 663 from 766 and we're left with 103.
Grab the next digit (1) from the dividend, add it to 103, then carry on: 1031 / 663

Moving on to step 4:
When dividing 1031 by 663, we get 1 with a remainder of 368.
The next digit of our result is 1. 
Result so far: 11.0
Subtracting 663 from 1031 leaves us with 368.
Bring next digit (0) of the dividend behind the 368 and repeat the process: 3680 / 663

Advancing to step 5:
When dividing 3680 by 663, we get 5 with a remainder of 365.
Put 5 as the next digit of the answer. 
Result so far: 115.0
If we subtract 3315 from 3680, we get 365.
Include the next digit (8) from the dividend after 365, then repeat: 3658 / 663

Step 6:
If we divide 3658 by 663, we get 5 and a remainder of 343.
The number 5 becomes the next digit in our result. 
Result so far: 1155.0
If we take 3315 away from 3658, we end up with 343.
Fetch the next digit (7) from the dividend, attach it to 343 and continue: 3437 / 663

Step 7:
663 goes into 3437 5 times with a remainder of 122.
Record the quotient 5 as the next digit in the result. 
Result so far: 11555.0
If we take 3315 away from 3437, we end up with 122.
Bring next digit (6) of the dividend behind the 122 and repeat the process: 1226 / 663

Let's proceed to step 8:
663 goes into 1226 1 times with a remainder of 563.
Write down 1 as next digit of the result. 
Result so far: 115551.0
Subtract 663 from 1226 to get 563.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5630, and continue the process.

Let's proceed to step 9:
5630 divided by 663 is 8 with a remainder of 326.
Put 8 as the next digit of the answer. 
Result so far: 115551.8
Subtracting 5304 from 5630 leaves us with 326.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

Advancing to step 10:
663 can be fit into 3260 4 times, resulting in a remainder of 608.
The number 4 becomes the next digit in our result. 
Result so far: 115551.84
If we subtract 2652 from 3260, we get 608.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

Let's proceed to step 11:
663 goes into 6080 9 times with a remainder of 113.
The number 9 becomes the next digit in our result. 
Result so far: 115551.849
Subtracting 5967 from 6080 leaves us with 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Moving on to step 12:
663 goes into 1130 1 times with a remainder of 467.
Record the quotient 1 as the next digit in the result. 
Result so far: 115551.8491
The remainder is 467 after subtracting 663 from 1130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4670, and continue the process.

Step 13:
The number 663 fits into 4670 7 times, leaving a remainder of 29.
The number 7 becomes the next digit in our result. 
Result so far: 115551.84917
The remainder is 29 after subtracting 4641 from 4670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 14:
663 goes into 290 0 times with a remainder of 290.
Put 0 as the next digit of the answer. 
Result so far: 115551.84917
Deduct 0 from 290 and we're left with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Going ahead to step 15:
2900 divided by 663 is 4 with a remainder of 248.
The number 4 becomes the next digit in our result. 
Result so far: 115551.8491704
Subtract 2652 from 2900 to get 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Advancing to step 16:
When dividing 2480 by 663, we get 3 with a remainder of 491.
Put 3 as the next digit of the answer. 
Result so far: 115551.84917043
Deduct 1989 from 2480 and we're left with 491.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4910, and continue the process.

After the division, we end up with 115551.84917043 and a remainder of 4.91e-07.
