Let's divide 15153167 by 640
We want to figure out the number of times 15153167 can be divided by 640.

Let's proceed to step 1:
1 divided by 640 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 640

Step 2:
640 can be fit into 15 0 times, resulting in a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 15 to get 15.
Fetch the next digit (1) from the dividend, attach it to 15 and continue: 151 / 640

On to step 3:
The number 640 fits into 151 0 times, leaving a remainder of 151.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 151, we end up with 151.
Take the next digit (5) from the dividend and append it to 151, then repeat: 1515 / 640

Moving on to step 4:
If we divide 1515 by 640, we get 2 and a remainder of 235.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 1280 from 1515 to get 235.
Fetch the next digit (3) from the dividend, attach it to 235 and continue: 2353 / 640

Let's proceed to step 5:
If we divide 2353 by 640, we get 3 and a remainder of 433.
The number 3 becomes the next digit in our result. 
Result so far: 23.0
Subtracting 1920 from 2353 leaves us with 433.
Append the next digit (1) from the dividend to 433 and continue with: 4331 / 640

Step 6:
640 goes into 4331 6 times with a remainder of 491.
Record the quotient 6 as the next digit in the result. 
Result so far: 236.0
Subtract 3840 from 4331 to get 491.
Append the next digit (6) from the dividend to 491 and continue with: 4916 / 640

Let's proceed to step 7:
4916 divided by 640 is 7 with a remainder of 436.
Use 7 as the next digit of our solution. 
Result so far: 2367.0
If we subtract 4480 from 4916, we get 436.
Grab the next digit (7) from the dividend, add it to 436, then carry on: 4367 / 640

Step 8:
The number 640 fits into 4367 6 times, leaving a remainder of 527.
The next digit of our result is 6. 
Result so far: 23676.0
The remainder is 527 after subtracting 3840 from 4367.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5270, and continue the process.

Moving on to step 9:
If we divide 5270 by 640, we get 8 and a remainder of 150.
The number 8 becomes the next digit in our result. 
Result so far: 23676.8
Deduct 5120 from 5270 and we're left with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Advancing to step 10:
1500 divided by 640 is 2 with a remainder of 220.
Use 2 as the next digit of our solution. 
Result so far: 23676.82
The remainder is 220 after subtracting 1280 from 1500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Step 11:
640 goes into 2200 3 times with a remainder of 280.
The next digit of our result is 3. 
Result so far: 23676.823
Subtracting 1920 from 2200 leaves us with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Let's proceed to step 12:
640 can be fit into 2800 4 times, resulting in a remainder of 240.
Put 4 as the next digit of the answer. 
Result so far: 23676.8234
Deduct 2560 from 2800 and we're left with 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:
The number 640 fits into 2400 3 times, leaving a remainder of 480.
The next digit of our result is 3. 
Result so far: 23676.82343
If we take 1920 away from 2400, we end up with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Moving on to step 14:
If we divide 4800 by 640, we get 7 and a remainder of 320.
Record the quotient 7 as the next digit in the result. 
Result so far: 23676.823437
Subtracting 4480 from 4800 leaves us 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.

Moving on to step 15:
The number 640 fits into 3200 5 times, leaving a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 23676.8234375
The remainder is 0 after subtracting 3200 from 3200.
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:
The number 640 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 23676.8234375
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 23676.8234375 with a balance of 0.0.
