51179205 ÷ 640 
We want to divide 51179205 by 640.

Moving on to step 1:
If we divide 5 by 640, we get 0 and a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 640

Moving on to step 2:
When dividing 51 by 640, we get 0 with a remainder of 51.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 51, we end up with 51.
Grab the next digit (1) from the dividend, add it to 51, then carry on: 511 / 640

On to step 3:
640 can be fit into 511 0 times, resulting in a remainder of 511.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 511 after subtracting 0 from 511.
Grab the next digit (7) from the dividend, add it to 511, then carry on: 5117 / 640

Moving on to step 4:
640 can be fit into 5117 7 times, resulting in a remainder of 637.
The next digit of our result is 7. 
Result so far: 7.0
Subtracting 4480 from 5117 leaves us with 637.
Take the next digit (9) from the dividend and append it to 637, then repeat: 6379 / 640

Step 5:
When dividing 6379 by 640, we get 9 with a remainder of 619.
The number 9 becomes the next digit in our result. 
Result so far: 79.0
Subtract 5760 from 6379 to get 619.
Bring next digit (2) of the dividend behind the 619 and repeat the process: 6192 / 640

Let's proceed to step 6:
When dividing 6192 by 640, we get 9 with a remainder of 432.
Record the quotient 9 as the next digit in the result. 
Result so far: 799.0
If we subtract 5760 from 6192, we get 432.
Fetch the next digit (0) from the dividend, attach it to 432 and continue: 4320 / 640

Advancing to step 7:
640 goes into 4320 6 times with a remainder of 480.
The number 6 becomes the next digit in our result. 
Result so far: 7996.0
If we take 3840 away from 4320, we end up with 480.
Take the next digit (5) from the dividend and append it to 480, then repeat: 4805 / 640

Going ahead to step 8:
640 goes into 4805 7 times with a remainder of 325.
The next digit of our result is 7. 
Result so far: 79967.0
Deduct 4480 from 4805 and we're left with 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Going ahead to step 9:
The number 640 fits into 3250 5 times, leaving a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 79967.5
If we subtract 3200 from 3250, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 10:
If we divide 500 by 640, we get 0 and a remainder of 500.
Use 0 as the next digit of our solution. 
Result so far: 79967.5
If we take 0 away from 500, we end up with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Advancing to step 11:
640 can be fit into 5000 7 times, resulting in a remainder of 520.
Write down 7 as next digit of the result. 
Result so far: 79967.507
If we subtract 4480 from 5000, we get 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Going ahead to step 12:
If we divide 5200 by 640, we get 8 and a remainder of 80.
Use 8 as the next digit of our solution. 
Result so far: 79967.5078
The remainder is 80 after subtracting 5120 from 5200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 13:
If we divide 800 by 640, we get 1 and a remainder of 160.
Record the quotient 1 as the next digit in the result. 
Result so far: 79967.50781
If we subtract 640 from 800, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Step 14:
The number 640 fits into 1600 2 times, leaving a remainder of 320.
Write down 2 as next digit of the result. 
Result so far: 79967.507812
Subtracting 1280 from 1600 leaves us 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.

Step 15:
3200 divided by 640 is 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 79967.5078125
Subtracting 3200 from 3200 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.

Moving on to step 16:
640 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 79967.5078125
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 79967.5078125 with a remaining 0.0.
