We look at the division of 61499720 by 663 
The aim is to understand the frequency of 663 in 61499720.

On to step 1:
The number 663 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (1) of the dividend behind the 6 and repeat the process: 61 / 663

Step 2:
663 can be fit into 61 0 times, resulting in a remainder of 61.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 61 and we're left with 61.
Fetch the next digit (4) from the dividend, attach it to 61 and continue: 614 / 663

Advancing to step 3:
663 can be fit into 614 0 times, resulting in a remainder of 614.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 614 leaves us with 614.
Append the next digit (9) from the dividend to 614 and continue with: 6149 / 663

On to step 4:
6149 divided by 663 is 9 with a remainder of 182.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Deduct 5967 from 6149 and we're left with 182.
Grab the next digit (9) from the dividend, add it to 182, then carry on: 1829 / 663

Advancing to step 5:
663 goes into 1829 2 times with a remainder of 503.
Put 2 as the next digit of the answer. 
Result so far: 92.0
The remainder is 503 after subtracting 1326 from 1829.
Append the next digit (7) from the dividend to 503 and continue with: 5037 / 663

On to step 6:
When dividing 5037 by 663, we get 7 with a remainder of 396.
The next digit of our result is 7. 
Result so far: 927.0
Subtracting 4641 from 5037 leaves us with 396.
Append the next digit (2) from the dividend to 396 and continue with: 3962 / 663

Going ahead to step 7:
The number 663 fits into 3962 5 times, leaving a remainder of 647.
Write down 5 as next digit of the result. 
Result so far: 9275.0
If we take 3315 away from 3962, we end up with 647.
Take the next digit (0) from the dividend and append it to 647, then repeat: 6470 / 663

Let's proceed to step 8:
If we divide 6470 by 663, we get 9 and a remainder of 503.
The next digit of our result is 9. 
Result so far: 92759.0
Deduct 5967 from 6470 and we're left with 503.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5030, and continue the process.

Moving on to step 9:
If we divide 5030 by 663, we get 7 and a remainder of 389.
The number 7 becomes the next digit in our result. 
Result so far: 92759.7
Subtract 4641 from 5030 to get 389.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3890, and continue the process.

Let's proceed to step 10:
If we divide 3890 by 663, we get 5 and a remainder of 575.
Record the quotient 5 as the next digit in the result. 
Result so far: 92759.75
If we take 3315 away from 3890, we end up with 575.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5750, and continue the process.

Step 11:
When dividing 5750 by 663, we get 8 with a remainder of 446.
Record the quotient 8 as the next digit in the result. 
Result so far: 92759.758
Subtracting 5304 from 5750 leaves us with 446.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4460, and continue the process.

Let's proceed to step 12:
4460 divided by 663 is 6 with a remainder of 482.
Write down 6 as next digit of the result. 
Result so far: 92759.7586
The remainder is 482 after subtracting 3978 from 4460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4820, and continue the process.

Going ahead to step 13:
4820 divided by 663 is 7 with a remainder of 179.
The number 7 becomes the next digit in our result. 
Result so far: 92759.75867
Subtracting 4641 from 4820 leaves us with 179.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

Moving on to step 14:
1790 divided by 663 is 2 with a remainder of 464.
The number 2 becomes the next digit in our result. 
Result so far: 92759.758672
The remainder is 464 after subtracting 1326 from 1790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Moving on to step 15:
4640 divided by 663 is 6 with a remainder of 662.
The number 6 becomes the next digit in our result. 
Result so far: 92759.7586726
Subtract 3978 from 4640 to get 662.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6620, and continue the process.

Let's proceed to step 16:
When dividing 6620 by 663, we get 9 with a remainder of 653.
The number 9 becomes the next digit in our result. 
Result so far: 92759.75867269
If we subtract 5967 from 6620, we get 653.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6530, and continue the process.

In conclusion, the division gives 92759.75867269 with a balance of 6.53e-07.
