We divide 10138162 by 640
We're looking to find how many times 640 goes into 10138162.

Going ahead to step 1:
If we divide 1 by 640, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 640

Advancing to step 2:
640 can be fit into 10 0 times, resulting in a remainder of 10.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 10 to get 10.
Grab the next digit (1) from the dividend, add it to 10, then carry on: 101 / 640

Let's proceed to step 3:
If we divide 101 by 640, we get 0 and a remainder of 101.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 101, we get 101.
Grab the next digit (3) from the dividend, add it to 101, then carry on: 1013 / 640

Going ahead to step 4:
If we divide 1013 by 640, we get 1 and a remainder of 373.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 640 from 1013 to get 373.
Grab the next digit (8) from the dividend, add it to 373, then carry on: 3738 / 640

Advancing to step 5:
If we divide 3738 by 640, we get 5 and a remainder of 538.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Deduct 3200 from 3738 and we're left with 538.
Include the next digit (1) from the dividend after 538, then repeat: 5381 / 640

On to step 6:
5381 divided by 640 is 8 with a remainder of 261.
Use 8 as the next digit of our solution. 
Result so far: 158.0
If we take 5120 away from 5381, we end up with 261.
Bring next digit (6) of the dividend behind the 261 and repeat the process: 2616 / 640

Advancing to step 7:
The number 640 fits into 2616 4 times, leaving a remainder of 56.
Put 4 as the next digit of the answer. 
Result so far: 1584.0
If we subtract 2560 from 2616, we get 56.
Fetch the next digit (2) from the dividend, attach it to 56 and continue: 562 / 640

Moving on to step 8:
When dividing 562 by 640, we get 0 with a remainder of 562.
Write down 0 as next digit of the result. 
Result so far: 15840.0
If we take 0 away from 562, we end up with 562.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5620, and continue the process.

Moving on to step 9:
5620 divided by 640 is 8 with a remainder of 500.
The next digit of our result is 8. 
Result so far: 15840.8
Subtracting 5120 from 5620 leaves us with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Let's proceed to step 10:
The number 640 fits into 5000 7 times, leaving a remainder of 520.
Use 7 as the next digit of our solution. 
Result so far: 15840.87
Subtract 4480 from 5000 to get 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Going ahead to step 11:
5200 divided by 640 is 8 with a remainder of 80.
The next digit of our result is 8. 
Result so far: 15840.878
The remainder is 80 after subtracting 5120 from 5200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 12:
640 can be fit into 800 1 times, resulting in a remainder of 160.
Use 1 as the next digit of our solution. 
Result so far: 15840.8781
The remainder is 160 after subtracting 640 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 13:
If we divide 1600 by 640, we get 2 and a remainder of 320.
The next digit of our result is 2. 
Result so far: 15840.87812
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.

Moving on to step 14:
When dividing 3200 by 640, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 15840.878125
Subtracting 3200 from 3200 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.

Step 15:
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: 15840.878125
Deduct 0 from 0 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.

Going ahead to step 16:
640 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 15840.878125
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.

Our division results in 15840.878125 with a remaining 0.0.
