We're dividing 640651 by 54 
Our goal is to divide 640651 by 54.

Step 1:
The number 54 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 54

Let's proceed to step 2:
54 can be fit into 64 1 times, resulting in a remainder of 10.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 54 from 64 to get 10.
Bring next digit (0) of the dividend behind the 10 and repeat the process: 100 / 54

Going ahead to step 3:
100 divided by 54 is 1 with a remainder of 46.
Write down 1 as next digit of the result. 
Result so far: 11.0
Deduct 54 from 100 and we're left with 46.
Include the next digit (6) from the dividend after 46, then repeat: 466 / 54

Let's proceed to step 4:
54 goes into 466 8 times with a remainder of 34.
Write down 8 as next digit of the result. 
Result so far: 118.0
If we subtract 432 from 466, we get 34.
Append the next digit (5) from the dividend to 34 and continue with: 345 / 54

Going ahead to step 5:
The number 54 fits into 345 6 times, leaving a remainder of 21.
Use 6 as the next digit of our solution. 
Result so far: 1186.0
Subtract 324 from 345 to get 21.
Bring next digit (1) of the dividend behind the 21 and repeat the process: 211 / 54

Advancing to step 6:
54 goes into 211 3 times with a remainder of 49.
Put 3 as the next digit of the answer. 
Result so far: 11863.0
Deduct 162 from 211 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Moving on to step 7:
The number 54 fits into 490 9 times, leaving a remainder of 4.
The next digit of our result is 9. 
Result so far: 11863.9
The remainder is 4 after subtracting 486 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 8:
54 can be fit into 40 0 times, resulting in a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 11863.9
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.

Step 9:
If we divide 400 by 54, we get 7 and a remainder of 22.
Use 7 as the next digit of our solution. 
Result so far: 11863.907
If we take 378 away from 400, we end up 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.

Moving on to step 10:
If we divide 220 by 54, we get 4 and a remainder of 4.
The next digit of our result is 4. 
Result so far: 11863.9074
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.

Advancing to step 11:
When dividing 40 by 54, we get 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 11863.9074
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.

Let's proceed to step 12:
54 goes into 400 7 times with a remainder of 22.
The next digit of our result is 7. 
Result so far: 11863.907407
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 13:
54 goes into 220 4 times with a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 11863.9074074
If we take 216 away from 220, we end up 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.

Let's proceed to step 14:
54 can be fit into 40 0 times, resulting in a remainder of 40.
The next digit of our result is 0. 
Result so far: 11863.9074074
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

After the division, we end up with 11863.9074074 and a remainder of 4e-08.
