Let's divide 7744802 by 640
We want to divide 7744802 by 640.

Advancing to step 1:
640 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 640

Let's proceed to step 2:
77 divided by 640 is 0 with a remainder of 77.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 77 to get 77.
Grab the next digit (4) from the dividend, add it to 77, then carry on: 774 / 640

Going ahead to step 3:
774 divided by 640 is 1 with a remainder of 134.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 640 from 774 and we're left with 134.
Grab the next digit (4) from the dividend, add it to 134, then carry on: 1344 / 640

Going ahead to step 4:
When dividing 1344 by 640, we get 2 with a remainder of 64.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we subtract 1280 from 1344, we get 64.
Grab the next digit (8) from the dividend, add it to 64, then carry on: 648 / 640

Let's proceed to step 5:
If we divide 648 by 640, we get 1 and a remainder of 8.
The next digit of our result is 1. 
Result so far: 121.0
The remainder is 8 after subtracting 640 from 648.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 640

On to step 6:
If we divide 80 by 640, we get 0 and a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 1210.0
Subtract 0 from 80 to get 80.
Append the next digit (2) from the dividend to 80 and continue with: 802 / 640

Moving on to step 7:
When dividing 802 by 640, we get 1 with a remainder of 162.
The number 1 becomes the next digit in our result. 
Result so far: 12101.0
Deduct 640 from 802 and we're left with 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Going ahead to step 8:
640 goes into 1620 2 times with a remainder of 340.
Put 2 as the next digit of the answer. 
Result so far: 12101.2
Subtract 1280 from 1620 to get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Going ahead to step 9:
3400 divided by 640 is 5 with a remainder of 200.
The number 5 becomes the next digit in our result. 
Result so far: 12101.25
Subtract 3200 from 3400 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Let's proceed to step 10:
640 can be fit into 2000 3 times, resulting in a remainder of 80.
Put 3 as the next digit of the answer. 
Result so far: 12101.253
Subtracting 1920 from 2000 leaves us 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 11:
800 divided by 640 is 1 with a remainder of 160.
The next digit of our result is 1. 
Result so far: 12101.2531
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.

Let's proceed to step 12:
If we divide 1600 by 640, we get 2 and a remainder of 320.
Write down 2 as next digit of the result. 
Result so far: 12101.25312
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.

Going ahead to step 13:
If we divide 3200 by 640, we get 5 and a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 12101.253125
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.

Going ahead to step 14:
640 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 12101.253125
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.

Let's proceed to step 15:
640 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 12101.253125
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.

The final outcome is 12101.253125, with a leftover of 0.0.
