73800793 divided by 640 
We're looking to find how many times 640 goes into 73800793.

Advancing to step 1:
The number 640 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 640

Let's proceed to step 2:
When dividing 73 by 640, we get 0 with a remainder of 73.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 73, we end up with 73.
Bring next digit (8) of the dividend behind the 73 and repeat the process: 738 / 640

Advancing to step 3:
When dividing 738 by 640, we get 1 with a remainder of 98.
The next digit of our result is 1. 
Result so far: 1.0
If we take 640 away from 738, we end up with 98.
Bring next digit (0) of the dividend behind the 98 and repeat the process: 980 / 640

Step 4:
640 goes into 980 1 times with a remainder of 340.
Use 1 as the next digit of our solution. 
Result so far: 11.0
If we take 640 away from 980, we end up with 340.
Take the next digit (0) from the dividend and append it to 340, then repeat: 3400 / 640

Step 5:
If we divide 3400 by 640, we get 5 and a remainder of 200.
The next digit of our result is 5. 
Result so far: 115.0
If we subtract 3200 from 3400, we get 200.
Bring next digit (7) of the dividend behind the 200 and repeat the process: 2007 / 640

Let's proceed to step 6:
640 can be fit into 2007 3 times, resulting in a remainder of 87.
Put 3 as the next digit of the answer. 
Result so far: 1153.0
Subtracting 1920 from 2007 leaves us with 87.
Fetch the next digit (9) from the dividend, attach it to 87 and continue: 879 / 640

Advancing to step 7:
879 divided by 640 is 1 with a remainder of 239.
Record the quotient 1 as the next digit in the result. 
Result so far: 11531.0
If we subtract 640 from 879, we get 239.
Include the next digit (3) from the dividend after 239, then repeat: 2393 / 640

On to step 8:
640 can be fit into 2393 3 times, resulting in a remainder of 473.
Record the quotient 3 as the next digit in the result. 
Result so far: 115313.0
Deduct 1920 from 2393 and we're left with 473.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4730, and continue the process.

Let's proceed to step 9:
If we divide 4730 by 640, we get 7 and a remainder of 250.
Record the quotient 7 as the next digit in the result. 
Result so far: 115313.7
If we take 4480 away from 4730, we end up with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Advancing to step 10:
640 goes into 2500 3 times with a remainder of 580.
The number 3 becomes the next digit in our result. 
Result so far: 115313.73
Subtracting 1920 from 2500 leaves us with 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

On to step 11:
640 can be fit into 5800 9 times, resulting in a remainder of 40.
Use 9 as the next digit of our solution. 
Result so far: 115313.739
If we subtract 5760 from 5800, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 12:
640 goes into 400 0 times with a remainder of 400.
Record the quotient 0 as the next digit in the result. 
Result so far: 115313.739
Deduct 0 from 400 and we're left with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Advancing to step 13:
If we divide 4000 by 640, we get 6 and a remainder of 160.
The number 6 becomes the next digit in our result. 
Result so far: 115313.73906
The remainder is 160 after subtracting 3840 from 4000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 14:
1600 divided by 640 is 2 with a remainder of 320.
Write down 2 as next digit of the result. 
Result so far: 115313.739062
Deduct 1280 from 1600 and we're left 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 15:
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: 115313.7390625
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.

Moving on to step 16:
When dividing 0 by 640, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 115313.7390625
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.

The final result is 115313.7390625 with a remainder of 0.0.
