Let's divide 77482681 by 629
The aim is to understand the frequency of 629 in 77482681.

On to step 1:
If we divide 7 by 629, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 629

Step 2:
77 divided by 629 is 0 with a remainder of 77.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 77 to get 77.
Grab the next digit (4) from the dividend, add it to 77, then carry on: 774 / 629

Step 3:
The number 629 fits into 774 1 times, leaving a remainder of 145.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 629 from 774 to get 145.
Include the next digit (8) from the dividend after 145, then repeat: 1458 / 629

Moving on to step 4:
The number 629 fits into 1458 2 times, leaving a remainder of 200.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we take 1258 away from 1458, we end up with 200.
Append the next digit (2) from the dividend to 200 and continue with: 2002 / 629

On to step 5:
If we divide 2002 by 629, we get 3 and a remainder of 115.
The number 3 becomes the next digit in our result. 
Result so far: 123.0
Subtract 1887 from 2002 to get 115.
Bring next digit (6) of the dividend behind the 115 and repeat the process: 1156 / 629

Going ahead to step 6:
629 goes into 1156 1 times with a remainder of 527.
Record the quotient 1 as the next digit in the result. 
Result so far: 1231.0
The remainder is 527 after subtracting 629 from 1156.
Take the next digit (8) from the dividend and append it to 527, then repeat: 5278 / 629

Let's proceed to step 7:
5278 divided by 629 is 8 with a remainder of 246.
The number 8 becomes the next digit in our result. 
Result so far: 12318.0
If we subtract 5032 from 5278, we get 246.
Grab the next digit (1) from the dividend, add it to 246, then carry on: 2461 / 629

Let's proceed to step 8:
If we divide 2461 by 629, we get 3 and a remainder of 574.
The number 3 becomes the next digit in our result. 
Result so far: 123183.0
Deduct 1887 from 2461 and we're left with 574.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5740, and continue the process.

Step 9:
When dividing 5740 by 629, we get 9 with a remainder of 79.
The next digit of our result is 9. 
Result so far: 123183.9
Deduct 5661 from 5740 and we're left with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Step 10:
The number 629 fits into 790 1 times, leaving a remainder of 161.
Write down 1 as next digit of the result. 
Result so far: 123183.91
Subtract 629 from 790 to get 161.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1610, and continue the process.

On to step 11:
The number 629 fits into 1610 2 times, leaving a remainder of 352.
Put 2 as the next digit of the answer. 
Result so far: 123183.912
If we subtract 1258 from 1610, we get 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Going ahead to step 12:
3520 divided by 629 is 5 with a remainder of 375.
Put 5 as the next digit of the answer. 
Result so far: 123183.9125
If we take 3145 away from 3520, we end up with 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Moving on to step 13:
The number 629 fits into 3750 5 times, leaving a remainder of 605.
Write down 5 as next digit of the result. 
Result so far: 123183.91255
Subtract 3145 from 3750 to get 605.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6050, and continue the process.

After the division, we end up with 123183.91255 and a remainder of 0.000605.
