Let's divide 64948167 by 640
The aim is to understand the frequency of 640 in 64948167.

Going ahead to step 1:
When dividing 6 by 640, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 640

Going ahead to step 2:
When dividing 64 by 640, we get 0 with a remainder of 64.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 64, we end up with 64.
Fetch the next digit (9) from the dividend, attach it to 64 and continue: 649 / 640

Advancing to step 3:
When dividing 649 by 640, we get 1 with a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 640 from 649, we get 9.
Include the next digit (4) from the dividend after 9, then repeat: 94 / 640

Let's proceed to step 4:
If we divide 94 by 640, we get 0 and a remainder of 94.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Deduct 0 from 94 and we're left with 94.
Take the next digit (8) from the dividend and append it to 94, then repeat: 948 / 640

Step 5:
The number 640 fits into 948 1 times, leaving a remainder of 308.
Record the quotient 1 as the next digit in the result. 
Result so far: 101.0
Subtracting 640 from 948 leaves us with 308.
Append the next digit (1) from the dividend to 308 and continue with: 3081 / 640

Let's proceed to step 6:
If we divide 3081 by 640, we get 4 and a remainder of 521.
Put 4 as the next digit of the answer. 
Result so far: 1014.0
If we subtract 2560 from 3081, we get 521.
Include the next digit (6) from the dividend after 521, then repeat: 5216 / 640

Step 7:
5216 divided by 640 is 8 with a remainder of 96.
Record the quotient 8 as the next digit in the result. 
Result so far: 10148.0
The remainder is 96 after subtracting 5120 from 5216.
Take the next digit (7) from the dividend and append it to 96, then repeat: 967 / 640

Going ahead to step 8:
967 divided by 640 is 1 with a remainder of 327.
Use 1 as the next digit of our solution. 
Result so far: 101481.0
Subtracting 640 from 967 leaves us with 327.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3270, and continue the process.

Advancing to step 9:
640 goes into 3270 5 times with a remainder of 70.
Put 5 as the next digit of the answer. 
Result so far: 101481.5
The remainder is 70 after subtracting 3200 from 3270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 10:
640 can be fit into 700 1 times, resulting in a remainder of 60.
Write down 1 as next digit of the result. 
Result so far: 101481.51
Deduct 640 from 700 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 11:
If we divide 600 by 640, we get 0 and a remainder of 600.
Use 0 as the next digit of our solution. 
Result so far: 101481.51
Subtract 0 from 600 to get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Moving on to step 12:
The number 640 fits into 6000 9 times, leaving a remainder of 240.
Put 9 as the next digit of the answer. 
Result so far: 101481.5109
Subtract 5760 from 6000 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Let's proceed to step 13:
2400 divided by 640 is 3 with a remainder of 480.
Use 3 as the next digit of our solution. 
Result so far: 101481.51093
The remainder is 480 after subtracting 1920 from 2400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Let's proceed to step 14:
If we divide 4800 by 640, we get 7 and a remainder of 320.
Write down 7 as next digit of the result. 
Result so far: 101481.510937
Deduct 4480 from 4800 and we're left with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

On to step 15:
If we divide 3200 by 640, we get 5 and a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 101481.5109375
If we take 3200 away from 3200, 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.

Advancing 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: 101481.5109375
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.

Our division results in 101481.5109375 with a remaining 0.0.
