We're dividing 80147410 by 640 
Our goal is to divide 80147410 by 640.

Moving on to step 1:
If we divide 8 by 640, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 640

Going ahead to step 2:
The number 640 fits into 80 0 times, leaving a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 80 leaves us with 80.
Bring next digit (1) of the dividend behind the 80 and repeat the process: 801 / 640

Let's proceed to step 3:
The number 640 fits into 801 1 times, leaving a remainder of 161.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 640 from 801 to get 161.
Include the next digit (4) from the dividend after 161, then repeat: 1614 / 640

Moving on to step 4:
640 goes into 1614 2 times with a remainder of 334.
The next digit of our result is 2. 
Result so far: 12.0
Subtract 1280 from 1614 to get 334.
Bring next digit (7) of the dividend behind the 334 and repeat the process: 3347 / 640

Step 5:
When dividing 3347 by 640, we get 5 with a remainder of 147.
Write down 5 as next digit of the result. 
Result so far: 125.0
Subtracting 3200 from 3347 leaves us with 147.
Fetch the next digit (4) from the dividend, attach it to 147 and continue: 1474 / 640

Going ahead to step 6:
640 can be fit into 1474 2 times, resulting in a remainder of 194.
The next digit of our result is 2. 
Result so far: 1252.0
Subtract 1280 from 1474 to get 194.
Grab the next digit (1) from the dividend, add it to 194, then carry on: 1941 / 640

Moving on to step 7:
The number 640 fits into 1941 3 times, leaving a remainder of 21.
Record the quotient 3 as the next digit in the result. 
Result so far: 12523.0
The remainder is 21 after subtracting 1920 from 1941.
Fetch the next digit (0) from the dividend, attach it to 21 and continue: 210 / 640

Let's proceed to step 8:
The number 640 fits into 210 0 times, leaving a remainder of 210.
Put 0 as the next digit of the answer. 
Result so far: 125230.0
Subtracting 0 from 210 leaves us with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Moving on to step 9:
640 can be fit into 2100 3 times, resulting in a remainder of 180.
The next digit of our result is 3. 
Result so far: 125230.3
Deduct 1920 from 2100 and we're left with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Advancing to step 10:
The number 640 fits into 1800 2 times, leaving a remainder of 520.
Record the quotient 2 as the next digit in the result. 
Result so far: 125230.32
Deduct 1280 from 1800 and we're left with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Step 11:
640 can be fit into 5200 8 times, resulting in a remainder of 80.
Write down 8 as next digit of the result. 
Result so far: 125230.328
If we take 5120 away from 5200, we end up 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.

Moving on to step 12:
If we divide 800 by 640, we get 1 and a remainder of 160.
Write down 1 as next digit of the result. 
Result so far: 125230.3281
Subtracting 640 from 800 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Step 13:
When dividing 1600 by 640, we get 2 with a remainder of 320.
The number 2 becomes the next digit in our result. 
Result so far: 125230.32812
If we take 1280 away from 1600, we end up 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.

Advancing to step 14:
640 goes into 3200 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 125230.328125
Subtract 3200 from 3200 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.

Step 15:
When dividing 0 by 640, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 125230.328125
The remainder is 0 after subtracting 0 from 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 16:
640 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 125230.328125
The remainder is 0 after subtracting 0 from 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 125230.328125 with a remaining 0.0.
