73286076 ÷ 640 
Our goal is to divide 73286076 by 640.

Let's proceed to step 1:
7 divided by 640 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (3) from the dividend, attach it to 7 and continue: 73 / 640

Moving on to step 2:
73 divided by 640 is 0 with a remainder of 73.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 73 after subtracting 0 from 73.
Grab the next digit (2) from the dividend, add it to 73, then carry on: 732 / 640

Moving on to step 3:
The number 640 fits into 732 1 times, leaving a remainder of 92.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 640 from 732 leaves us with 92.
Append the next digit (8) from the dividend to 92 and continue with: 928 / 640

On to step 4:
When dividing 928 by 640, we get 1 with a remainder of 288.
The next digit of our result is 1. 
Result so far: 11.0
Subtracting 640 from 928 leaves us with 288.
Take the next digit (6) from the dividend and append it to 288, then repeat: 2886 / 640

Going ahead to step 5:
640 goes into 2886 4 times with a remainder of 326.
Use 4 as the next digit of our solution. 
Result so far: 114.0
If we take 2560 away from 2886, we end up with 326.
Take the next digit (0) from the dividend and append it to 326, then repeat: 3260 / 640

On to step 6:
640 goes into 3260 5 times with a remainder of 60.
The next digit of our result is 5. 
Result so far: 1145.0
Subtracting 3200 from 3260 leaves us with 60.
Fetch the next digit (7) from the dividend, attach it to 60 and continue: 607 / 640

On to step 7:
607 divided by 640 is 0 with a remainder of 607.
The next digit of our result is 0. 
Result so far: 11450.0
Deduct 0 from 607 and we're left with 607.
Append the next digit (6) from the dividend to 607 and continue with: 6076 / 640

Moving on to step 8:
640 can be fit into 6076 9 times, resulting in a remainder of 316.
Record the quotient 9 as the next digit in the result. 
Result so far: 114509.0
If we take 5760 away from 6076, we end up with 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

Advancing to step 9:
3160 divided by 640 is 4 with a remainder of 600.
Record the quotient 4 as the next digit in the result. 
Result so far: 114509.4
Subtracting 2560 from 3160 leaves us with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Advancing to step 10:
The number 640 fits into 6000 9 times, leaving a remainder of 240.
Use 9 as the next digit of our solution. 
Result so far: 114509.49
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:
If we divide 2400 by 640, we get 3 and a remainder of 480.
Use 3 as the next digit of our solution. 
Result so far: 114509.493
The remainder is 480 after subtracting 1920 from 2400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Going ahead to step 12:
4800 divided by 640 is 7 with a remainder of 320.
The number 7 becomes the next digit in our result. 
Result so far: 114509.4937
If we subtract 4480 from 4800, we 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.

Going ahead to step 13:
The number 640 fits into 3200 5 times, leaving a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 114509.49375
If we subtract 3200 from 3200, we 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.

Advancing to step 14:
The number 640 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 114509.49375
If we take 0 away from 0, we end up 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 15:
The number 640 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 114509.49375
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 114509.49375 with a remaining 0.0.
