We're dividing 1640166 by 640 
Our goal is to divide 1640166 by 640.

Moving on to step 1:
640 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 640

Moving on to step 2:
640 can be fit into 16 0 times, resulting in a remainder of 16.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 16, we end up with 16.
Fetch the next digit (4) from the dividend, attach it to 16 and continue: 164 / 640

Going ahead to step 3:
The number 640 fits into 164 0 times, leaving a remainder of 164.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 164, we get 164.
Grab the next digit (0) from the dividend, add it to 164, then carry on: 1640 / 640

Moving on to step 4:
When dividing 1640 by 640, we get 2 with a remainder of 360.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 360 after subtracting 1280 from 1640.
Bring next digit (1) of the dividend behind the 360 and repeat the process: 3601 / 640

Step 5:
The number 640 fits into 3601 5 times, leaving a remainder of 401.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
Subtracting 3200 from 3601 leaves us with 401.
Append the next digit (6) from the dividend to 401 and continue with: 4016 / 640

Advancing to step 6:
640 goes into 4016 6 times with a remainder of 176.
The next digit of our result is 6. 
Result so far: 256.0
Subtract 3840 from 4016 to get 176.
Take the next digit (6) from the dividend and append it to 176, then repeat: 1766 / 640

On to step 7:
When dividing 1766 by 640, we get 2 with a remainder of 486.
Use 2 as the next digit of our solution. 
Result so far: 2562.0
If we take 1280 away from 1766, we end up with 486.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4860, and continue the process.

Moving on to step 8:
640 can be fit into 4860 7 times, resulting in a remainder of 380.
Put 7 as the next digit of the answer. 
Result so far: 2562.7
Deduct 4480 from 4860 and we're left with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Going ahead to step 9:
The number 640 fits into 3800 5 times, leaving a remainder of 600.
Write down 5 as next digit of the result. 
Result so far: 2562.75
The remainder is 600 after subtracting 3200 from 3800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Let's proceed to step 10:
640 goes into 6000 9 times with a remainder of 240.
Use 9 as the next digit of our solution. 
Result so far: 2562.759
Subtracting 5760 from 6000 leaves us 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.

Advancing to step 11:
640 can be fit into 2400 3 times, resulting in a remainder of 480.
The number 3 becomes the next digit in our result. 
Result so far: 2562.7593
Subtracting 1920 from 2400 leaves us 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.

Let's proceed to step 12:
When dividing 4800 by 640, we get 7 with a remainder of 320.
Put 7 as the next digit of the answer. 
Result so far: 2562.75937
If we take 4480 away from 4800, 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.

Moving on to step 13:
640 can be fit into 3200 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 2562.759375
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.

Step 14:
640 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 2562.759375
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 15:
When dividing 0 by 640, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 2562.759375
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.

Our division results in 2562.759375 with a remaining 0.0.
