98843834 divided by 640 
The aim is to understand the frequency of 640 in 98843834.

Step 1:
640 can be fit into 9 0 times, resulting in a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Bring next digit (8) of the dividend behind the 9 and repeat the process: 98 / 640

Step 2:
640 can be fit into 98 0 times, resulting in a remainder of 98.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 98 to get 98.
Append the next digit (8) from the dividend to 98 and continue with: 988 / 640

Moving on to step 3:
The number 640 fits into 988 1 times, leaving a remainder of 348.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 640 from 988, we get 348.
Take the next digit (4) from the dividend and append it to 348, then repeat: 3484 / 640

Moving on to step 4:
The number 640 fits into 3484 5 times, leaving a remainder of 284.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Deduct 3200 from 3484 and we're left with 284.
Fetch the next digit (3) from the dividend, attach it to 284 and continue: 2843 / 640

Step 5:
640 can be fit into 2843 4 times, resulting in a remainder of 283.
The number 4 becomes the next digit in our result. 
Result so far: 154.0
If we take 2560 away from 2843, we end up with 283.
Grab the next digit (8) from the dividend, add it to 283, then carry on: 2838 / 640

Moving on to step 6:
If we divide 2838 by 640, we get 4 and a remainder of 278.
The number 4 becomes the next digit in our result. 
Result so far: 1544.0
Subtract 2560 from 2838 to get 278.
Append the next digit (3) from the dividend to 278 and continue with: 2783 / 640

Step 7:
640 goes into 2783 4 times with a remainder of 223.
Write down 4 as next digit of the result. 
Result so far: 15444.0
Deduct 2560 from 2783 and we're left with 223.
Take the next digit (4) from the dividend and append it to 223, then repeat: 2234 / 640

Let's proceed to step 8:
When dividing 2234 by 640, we get 3 with a remainder of 314.
Use 3 as the next digit of our solution. 
Result so far: 154443.0
Subtracting 1920 from 2234 leaves us with 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

On to step 9:
If we divide 3140 by 640, we get 4 and a remainder of 580.
Record the quotient 4 as the next digit in the result. 
Result so far: 154443.4
If we subtract 2560 from 3140, we get 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

On to step 10:
When dividing 5800 by 640, we get 9 with a remainder of 40.
Write down 9 as next digit of the result. 
Result so far: 154443.49
If we subtract 5760 from 5800, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 11:
400 divided by 640 is 0 with a remainder of 400.
The next digit of our result is 0. 
Result so far: 154443.49
Deduct 0 from 400 and we're left with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Step 12:
When dividing 4000 by 640, we get 6 with a remainder of 160.
Write down 6 as next digit of the result. 
Result so far: 154443.4906
The remainder is 160 after subtracting 3840 from 4000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 13:
640 goes into 1600 2 times with a remainder of 320.
Put 2 as the next digit of the answer. 
Result so far: 154443.49062
Subtract 1280 from 1600 to get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Step 14:
When dividing 3200 by 640, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 154443.490625
Deduct 3200 from 3200 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 15:
0 divided by 640 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 154443.490625
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 16:
0 divided by 640 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 154443.490625
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 154443.490625 and a remainder of 0.0.
