69714630 ÷ 663 
The aim is to understand the frequency of 663 in 69714630.

Let's proceed to step 1:
The number 663 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 663

Going ahead to step 2:
69 divided by 663 is 0 with a remainder of 69.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 69, we end up with 69.
Bring next digit (7) of the dividend behind the 69 and repeat the process: 697 / 663

Let's proceed to step 3:
The number 663 fits into 697 1 times, leaving a remainder of 34.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 663 from 697 and we're left with 34.
Bring next digit (1) of the dividend behind the 34 and repeat the process: 341 / 663

Step 4:
The number 663 fits into 341 0 times, leaving a remainder of 341.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we subtract 0 from 341, we get 341.
Append the next digit (4) from the dividend to 341 and continue with: 3414 / 663

Going ahead to step 5:
663 can be fit into 3414 5 times, resulting in a remainder of 99.
Use 5 as the next digit of our solution. 
Result so far: 105.0
Subtract 3315 from 3414 to get 99.
Take the next digit (6) from the dividend and append it to 99, then repeat: 996 / 663

Advancing to step 6:
If we divide 996 by 663, we get 1 and a remainder of 333.
Put 1 as the next digit of the answer. 
Result so far: 1051.0
Deduct 663 from 996 and we're left with 333.
Take the next digit (3) from the dividend and append it to 333, then repeat: 3333 / 663

Going ahead to step 7:
663 goes into 3333 5 times with a remainder of 18.
The next digit of our result is 5. 
Result so far: 10515.0
Subtracting 3315 from 3333 leaves us with 18.
Grab the next digit (0) from the dividend, add it to 18, then carry on: 180 / 663

Step 8:
When dividing 180 by 663, we get 0 with a remainder of 180.
Record the quotient 0 as the next digit in the result. 
Result so far: 105150.0
If we subtract 0 from 180, we get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Step 9:
663 can be fit into 1800 2 times, resulting in a remainder of 474.
Record the quotient 2 as the next digit in the result. 
Result so far: 105150.2
If we subtract 1326 from 1800, we get 474.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4740, and continue the process.

On to step 10:
663 can be fit into 4740 7 times, resulting in a remainder of 99.
Use 7 as the next digit of our solution. 
Result so far: 105150.27
Deduct 4641 from 4740 and we're left with 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Let's proceed to step 11:
If we divide 990 by 663, we get 1 and a remainder of 327.
Use 1 as the next digit of our solution. 
Result so far: 105150.271
If we subtract 663 from 990, we get 327.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3270, and continue the process.

On to step 12:
If we divide 3270 by 663, we get 4 and a remainder of 618.
The next digit of our result is 4. 
Result so far: 105150.2714
Subtract 2652 from 3270 to get 618.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6180, and continue the process.

Advancing to step 13:
The number 663 fits into 6180 9 times, leaving a remainder of 213.
The next digit of our result is 9. 
Result so far: 105150.27149
If we take 5967 away from 6180, we end up with 213.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2130, and continue the process.

On to step 14:
2130 divided by 663 is 3 with a remainder of 141.
Write down 3 as next digit of the result. 
Result so far: 105150.271493
Subtract 1989 from 2130 to get 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Let's proceed to step 15:
663 can be fit into 1410 2 times, resulting in a remainder of 84.
Record the quotient 2 as the next digit in the result. 
Result so far: 105150.2714932
If we take 1326 away from 1410, we end up with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Step 16:
When dividing 840 by 663, we get 1 with a remainder of 177.
The number 1 becomes the next digit in our result. 
Result so far: 105150.27149321
If we take 663 away from 840, we end up with 177.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

After the division, we end up with 105150.27149321 and a remainder of 1.77e-07.
