63600868 divided by 402 
The aim is to understand the frequency of 402 in 63600868.

Moving on to step 1:
6 divided by 402 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 402

Going ahead to step 2:
When dividing 63 by 402, we get 0 with a remainder of 63.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 63 leaves us with 63.
Take the next digit (6) from the dividend and append it to 63, then repeat: 636 / 402

Let's proceed to step 3:
402 goes into 636 1 times with a remainder of 234.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 402 from 636 to get 234.
Grab the next digit (0) from the dividend, add it to 234, then carry on: 2340 / 402

Step 4:
If we divide 2340 by 402, we get 5 and a remainder of 330.
The next digit of our result is 5. 
Result so far: 15.0
If we subtract 2010 from 2340, we get 330.
Append the next digit (0) from the dividend to 330 and continue with: 3300 / 402

Step 5:
402 can be fit into 3300 8 times, resulting in a remainder of 84.
The next digit of our result is 8. 
Result so far: 158.0
If we take 3216 away from 3300, we end up with 84.
Grab the next digit (8) from the dividend, add it to 84, then carry on: 848 / 402

Going ahead to step 6:
402 goes into 848 2 times with a remainder of 44.
The next digit of our result is 2. 
Result so far: 1582.0
Subtracting 804 from 848 leaves us with 44.
Take the next digit (6) from the dividend and append it to 44, then repeat: 446 / 402

On to step 7:
402 goes into 446 1 times with a remainder of 44.
Use 1 as the next digit of our solution. 
Result so far: 15821.0
If we subtract 402 from 446, we get 44.
Bring next digit (8) of the dividend behind the 44 and repeat the process: 448 / 402

Let's proceed to step 8:
The number 402 fits into 448 1 times, leaving a remainder of 46.
Record the quotient 1 as the next digit in the result. 
Result so far: 158211.0
If we subtract 402 from 448, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 9:
402 goes into 460 1 times with a remainder of 58.
Record the quotient 1 as the next digit in the result. 
Result so far: 158211.1
Subtract 402 from 460 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 10:
When dividing 580 by 402, we get 1 with a remainder of 178.
Put 1 as the next digit of the answer. 
Result so far: 158211.11
Subtracting 402 from 580 leaves us with 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

The quotient of the division is 158211.11, and the remainder is 0.178.
