Let's divide 49913834 by 663
The aim is to understand the frequency of 663 in 49913834.

On to step 1:
4 divided by 663 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Bring next digit (9) of the dividend behind the 4 and repeat the process: 49 / 663

On to step 2:
The number 663 fits into 49 0 times, leaving a remainder of 49.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 49 after subtracting 0 from 49.
Include the next digit (9) from the dividend after 49, then repeat: 499 / 663

Moving on to step 3:
When dividing 499 by 663, we get 0 with a remainder of 499.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 499, we end up with 499.
Include the next digit (1) from the dividend after 499, then repeat: 4991 / 663

Advancing to step 4:
4991 divided by 663 is 7 with a remainder of 350.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
The remainder is 350 after subtracting 4641 from 4991.
Fetch the next digit (3) from the dividend, attach it to 350 and continue: 3503 / 663

Going ahead to step 5:
3503 divided by 663 is 5 with a remainder of 188.
Write down 5 as next digit of the result. 
Result so far: 75.0
If we take 3315 away from 3503, we end up with 188.
Take the next digit (8) from the dividend and append it to 188, then repeat: 1888 / 663

On to step 6:
When dividing 1888 by 663, we get 2 with a remainder of 562.
Write down 2 as next digit of the result. 
Result so far: 752.0
Subtracting 1326 from 1888 leaves us with 562.
Bring next digit (3) of the dividend behind the 562 and repeat the process: 5623 / 663

Let's proceed to step 7:
5623 divided by 663 is 8 with a remainder of 319.
Write down 8 as next digit of the result. 
Result so far: 7528.0
If we take 5304 away from 5623, we end up with 319.
Include the next digit (4) from the dividend after 319, then repeat: 3194 / 663

Moving on to step 8:
If we divide 3194 by 663, we get 4 and a remainder of 542.
Use 4 as the next digit of our solution. 
Result so far: 75284.0
The remainder is 542 after subtracting 2652 from 3194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5420, and continue the process.

On to step 9:
663 goes into 5420 8 times with a remainder of 116.
Put 8 as the next digit of the answer. 
Result so far: 75284.8
If we subtract 5304 from 5420, we get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Step 10:
663 goes into 1160 1 times with a remainder of 497.
The next digit of our result is 1. 
Result so far: 75284.81
If we subtract 663 from 1160, we get 497.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4970, and continue the process.

Going ahead to step 11:
The number 663 fits into 4970 7 times, leaving a remainder of 329.
Record the quotient 7 as the next digit in the result. 
Result so far: 75284.817
If we take 4641 away from 4970, we end up with 329.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3290, and continue the process.

Going ahead to step 12:
663 goes into 3290 4 times with a remainder of 638.
Put 4 as the next digit of the answer. 
Result so far: 75284.8174
Deduct 2652 from 3290 and we're left with 638.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6380, and continue the process.

Moving on to step 13:
663 goes into 6380 9 times with a remainder of 413.
Record the quotient 9 as the next digit in the result. 
Result so far: 75284.81749
Subtract 5967 from 6380 to get 413.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4130, and continue the process.

Going ahead to step 14:
663 can be fit into 4130 6 times, resulting in a remainder of 152.
Write down 6 as next digit of the result. 
Result so far: 75284.817496
Subtract 3978 from 4130 to get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Moving on to step 15:
663 goes into 1520 2 times with a remainder of 194.
Write down 2 as next digit of the result. 
Result so far: 75284.8174962
The remainder is 194 after subtracting 1326 from 1520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Advancing to step 16:
663 can be fit into 1940 2 times, resulting in a remainder of 614.
The next digit of our result is 2. 
Result so far: 75284.81749622
If we take 1326 away from 1940, we end up with 614.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6140, and continue the process.

The quotient of the division is 75284.81749622, and the remainder is 6.14e-07.
