640777 divided by 54 
We want to figure out the number of times 640777 can be divided by 54.

Going ahead to step 1:
54 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 54

Let's proceed to step 2:
If we divide 64 by 54, we get 1 and a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 10 after subtracting 54 from 64.
Bring next digit (0) of the dividend behind the 10 and repeat the process: 100 / 54

Moving on to step 3:
If we divide 100 by 54, we get 1 and a remainder of 46.
The next digit of our result is 1. 
Result so far: 11.0
Subtract 54 from 100 to get 46.
Bring next digit (7) of the dividend behind the 46 and repeat the process: 467 / 54

Advancing to step 4:
54 goes into 467 8 times with a remainder of 35.
Write down 8 as next digit of the result. 
Result so far: 118.0
The remainder is 35 after subtracting 432 from 467.
Take the next digit (7) from the dividend and append it to 35, then repeat: 357 / 54

Advancing to step 5:
54 can be fit into 357 6 times, resulting in a remainder of 33.
The next digit of our result is 6. 
Result so far: 1186.0
Deduct 324 from 357 and we're left with 33.
Include the next digit (7) from the dividend after 33, then repeat: 337 / 54

Step 6:
337 divided by 54 is 6 with a remainder of 13.
Write down 6 as next digit of the result. 
Result so far: 11866.0
Subtract 324 from 337 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 7:
If we divide 130 by 54, we get 2 and a remainder of 22.
Record the quotient 2 as the next digit in the result. 
Result so far: 11866.2
Subtracting 108 from 130 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 8:
54 can be fit into 220 4 times, resulting in a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 11866.24
Subtract 216 from 220 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 9:
If we divide 40 by 54, we get 0 and a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 11866.24
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 10:
54 can be fit into 400 7 times, resulting in a remainder of 22.
The number 7 becomes the next digit in our result. 
Result so far: 11866.2407
Subtract 378 from 400 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 11:
The number 54 fits into 220 4 times, leaving a remainder of 4.
The next digit of our result is 4. 
Result so far: 11866.24074
Deduct 216 from 220 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 12:
The number 54 fits into 40 0 times, leaving a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 11866.24074
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 13:
The number 54 fits into 400 7 times, leaving a remainder of 22.
Put 7 as the next digit of the answer. 
Result so far: 11866.2407407
Deduct 378 from 400 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 14:
The number 54 fits into 220 4 times, leaving a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 11866.24074074
Subtracting 216 from 220 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

After the division, we end up with 11866.24074074 and a remainder of 4e-09.
