Let's divide 74819139 by 640
Our goal is to divide 74819139 by 640.

On to step 1:
7 divided by 640 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (4) from the dividend and append it to 7, then repeat: 74 / 640

Advancing to step 2:
74 divided by 640 is 0 with a remainder of 74.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 74 leaves us with 74.
Grab the next digit (8) from the dividend, add it to 74, then carry on: 748 / 640

Moving on to step 3:
748 divided by 640 is 1 with a remainder of 108.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 640 from 748 leaves us with 108.
Include the next digit (1) from the dividend after 108, then repeat: 1081 / 640

On to step 4:
If we divide 1081 by 640, we get 1 and a remainder of 441.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Deduct 640 from 1081 and we're left with 441.
Grab the next digit (9) from the dividend, add it to 441, then carry on: 4419 / 640

Step 5:
640 can be fit into 4419 6 times, resulting in a remainder of 579.
Put 6 as the next digit of the answer. 
Result so far: 116.0
Deduct 3840 from 4419 and we're left with 579.
Take the next digit (1) from the dividend and append it to 579, then repeat: 5791 / 640

Moving on to step 6:
640 can be fit into 5791 9 times, resulting in a remainder of 31.
The next digit of our result is 9. 
Result so far: 1169.0
If we take 5760 away from 5791, we end up with 31.
Grab the next digit (3) from the dividend, add it to 31, then carry on: 313 / 640

Let's proceed to step 7:
640 can be fit into 313 0 times, resulting in a remainder of 313.
The number 0 becomes the next digit in our result. 
Result so far: 11690.0
If we subtract 0 from 313, we get 313.
Fetch the next digit (9) from the dividend, attach it to 313 and continue: 3139 / 640

Going ahead to step 8:
If we divide 3139 by 640, we get 4 and a remainder of 579.
Put 4 as the next digit of the answer. 
Result so far: 116904.0
If we take 2560 away from 3139, we end up with 579.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5790, and continue the process.

On to step 9:
640 goes into 5790 9 times with a remainder of 30.
The number 9 becomes the next digit in our result. 
Result so far: 116904.9
Subtracting 5760 from 5790 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 10:
640 can be fit into 300 0 times, resulting in a remainder of 300.
Record the quotient 0 as the next digit in the result. 
Result so far: 116904.9
Subtracting 0 from 300 leaves us with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Advancing to step 11:
The number 640 fits into 3000 4 times, leaving a remainder of 440.
Record the quotient 4 as the next digit in the result. 
Result so far: 116904.904
If we take 2560 away from 3000, we end up with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Step 12:
If we divide 4400 by 640, we get 6 and a remainder of 560.
The number 6 becomes the next digit in our result. 
Result so far: 116904.9046
If we subtract 3840 from 4400, we get 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Advancing to step 13:
When dividing 5600 by 640, we get 8 with a remainder of 480.
Record the quotient 8 as the next digit in the result. 
Result so far: 116904.90468
If we take 5120 away from 5600, we end up 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 14:
If we divide 4800 by 640, we get 7 and a remainder of 320.
Put 7 as the next digit of the answer. 
Result so far: 116904.904687
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.

Going ahead to step 15:
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: 116904.9046875
If we take 3200 away from 3200, 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.

On to step 16:
0 divided by 640 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 116904.9046875
Subtract 0 from 0 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.

The quotient of the division is 116904.9046875, and the remainder is 0.0.
