We divide 640991 by 54
We're looking to find how many times 54 goes into 640991.

Step 1:
54 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 54

Advancing to step 2:
54 can be fit into 64 1 times, resulting in a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 54 from 64 leaves us with 10.
Grab the next digit (0) from the dividend, add it to 10, then carry on: 100 / 54

Advancing to step 3:
54 goes into 100 1 times with a remainder of 46.
The next digit of our result is 1. 
Result so far: 11.0
If we subtract 54 from 100, we get 46.
Include the next digit (9) from the dividend after 46, then repeat: 469 / 54

Step 4:
54 goes into 469 8 times with a remainder of 37.
The number 8 becomes the next digit in our result. 
Result so far: 118.0
If we subtract 432 from 469, we get 37.
Grab the next digit (9) from the dividend, add it to 37, then carry on: 379 / 54

Let's proceed to step 5:
The number 54 fits into 379 7 times, leaving a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 1187.0
Deduct 378 from 379 and we're left with 1.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 54

Moving on to step 6:
11 divided by 54 is 0 with a remainder of 11.
Record the quotient 0 as the next digit in the result. 
Result so far: 11870.0
Subtracting 0 from 11 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 7:
If we divide 110 by 54, we get 2 and a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 11870.2
Deduct 108 from 110 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 8:
54 goes into 20 0 times with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 11870.2
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 9:
54 can be fit into 200 3 times, resulting in a remainder of 38.
Use 3 as the next digit of our solution. 
Result so far: 11870.203
Subtracting 162 from 200 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 10:
If we divide 380 by 54, we get 7 and a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 11870.2037
If we take 378 away from 380, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 11:
20 divided by 54 is 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 11870.2037
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 12:
54 can be fit into 200 3 times, resulting in a remainder of 38.
Use 3 as the next digit of our solution. 
Result so far: 11870.203703
If we take 162 away from 200, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 13:
380 divided by 54 is 7 with a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 11870.2037037
If we subtract 378 from 380, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 14:
If we divide 20 by 54, we get 0 and a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 11870.2037037
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The quotient of the division is 11870.2037037, and the remainder is 2e-08.
