Let's divide 98505318 by 646
The aim is to understand the frequency of 646 in 98505318.

Going ahead to step 1:
9 divided by 646 is 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Fetch the next digit (8) from the dividend, attach it to 9 and continue: 98 / 646

Moving on to step 2:
646 goes into 98 0 times with a remainder of 98.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 98 after subtracting 0 from 98.
Append the next digit (5) from the dividend to 98 and continue with: 985 / 646

On to step 3:
When dividing 985 by 646, we get 1 with a remainder of 339.
The next digit of our result is 1. 
Result so far: 1.0
If we take 646 away from 985, we end up with 339.
Append the next digit (0) from the dividend to 339 and continue with: 3390 / 646

On to step 4:
The number 646 fits into 3390 5 times, leaving a remainder of 160.
Use 5 as the next digit of our solution. 
Result so far: 15.0
If we take 3230 away from 3390, we end up with 160.
Grab the next digit (5) from the dividend, add it to 160, then carry on: 1605 / 646

Step 5:
When dividing 1605 by 646, we get 2 with a remainder of 313.
Put 2 as the next digit of the answer. 
Result so far: 152.0
If we subtract 1292 from 1605, we get 313.
Grab the next digit (3) from the dividend, add it to 313, then carry on: 3133 / 646

Going ahead to step 6:
The number 646 fits into 3133 4 times, leaving a remainder of 549.
Write down 4 as next digit of the result. 
Result so far: 1524.0
If we take 2584 away from 3133, we end up with 549.
Take the next digit (1) from the dividend and append it to 549, then repeat: 5491 / 646

Let's proceed to step 7:
5491 divided by 646 is 8 with a remainder of 323.
The next digit of our result is 8. 
Result so far: 15248.0
If we subtract 5168 from 5491, we get 323.
Bring next digit (8) of the dividend behind the 323 and repeat the process: 3238 / 646

Moving on to step 8:
3238 divided by 646 is 5 with a remainder of 8.
The next digit of our result is 5. 
Result so far: 152485.0
Subtract 3230 from 3238 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 9:
80 divided by 646 is 0 with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 152485.0
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 10:
When dividing 800 by 646, we get 1 with a remainder of 154.
The next digit of our result is 1. 
Result so far: 152485.01
If we take 646 away from 800, we end up with 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Let's proceed to step 11:
If we divide 1540 by 646, we get 2 and a remainder of 248.
Write down 2 as next digit of the result. 
Result so far: 152485.012
Subtracting 1292 from 1540 leaves us with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Advancing to step 12:
646 goes into 2480 3 times with a remainder of 542.
Put 3 as the next digit of the answer. 
Result so far: 152485.0123
Subtract 1938 from 2480 to get 542.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5420, and continue the process.

Let's proceed to step 13:
When dividing 5420 by 646, we get 8 with a remainder of 252.
Use 8 as the next digit of our solution. 
Result so far: 152485.01238
The remainder is 252 after subtracting 5168 from 5420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Let's proceed to step 14:
When dividing 2520 by 646, we get 3 with a remainder of 582.
The number 3 becomes the next digit in our result. 
Result so far: 152485.012383
If we subtract 1938 from 2520, we get 582.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5820, and continue the process.

On to step 15:
646 goes into 5820 9 times with a remainder of 6.
Use 9 as the next digit of our solution. 
Result so far: 152485.0123839
If we subtract 5814 from 5820, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 16:
646 goes into 60 0 times with a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 152485.0123839
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The quotient of the division is 152485.0123839, and the remainder is 6e-08.
