663887 ÷ 57 
We want to figure out the number of times 663887 can be divided by 57.

Moving on to step 1:
57 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 57

Let's proceed to step 2:
If we divide 66 by 57, we get 1 and a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 9 after subtracting 57 from 66.
Grab the next digit (3) from the dividend, add it to 9, then carry on: 93 / 57

Moving on to step 3:
When dividing 93 by 57, we get 1 with a remainder of 36.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
The remainder is 36 after subtracting 57 from 93.
Bring next digit (8) of the dividend behind the 36 and repeat the process: 368 / 57

Step 4:
57 can be fit into 368 6 times, resulting in a remainder of 26.
Record the quotient 6 as the next digit in the result. 
Result so far: 116.0
If we subtract 342 from 368, we get 26.
Take the next digit (8) from the dividend and append it to 26, then repeat: 268 / 57

Let's proceed to step 5:
57 goes into 268 4 times with a remainder of 40.
Put 4 as the next digit of the answer. 
Result so far: 1164.0
Subtracting 228 from 268 leaves us with 40.
Bring next digit (7) of the dividend behind the 40 and repeat the process: 407 / 57

Advancing to step 6:
57 can be fit into 407 7 times, resulting in a remainder of 8.
Write down 7 as next digit of the result. 
Result so far: 11647.0
Deduct 399 from 407 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 7:
The number 57 fits into 80 1 times, leaving a remainder of 23.
Write down 1 as next digit of the result. 
Result so far: 11647.1
If we take 57 away from 80, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 8:
If we divide 230 by 57, we get 4 and a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 11647.14
The remainder is 2 after subtracting 228 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 9:
If we divide 20 by 57, we get 0 and a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 11647.14
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.

Advancing to step 10:
57 can be fit into 200 3 times, resulting in a remainder of 29.
Record the quotient 3 as the next digit in the result. 
Result so far: 11647.1403
If we subtract 171 from 200, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 11:
The number 57 fits into 290 5 times, leaving a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 11647.14035
Subtracting 285 from 290 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 12:
57 goes into 50 0 times with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 11647.14035
If we take 0 away from 50, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 13:
57 goes into 500 8 times with a remainder of 44.
The number 8 becomes the next digit in our result. 
Result so far: 11647.1403508
If we subtract 456 from 500, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 14:
The number 57 fits into 440 7 times, leaving a remainder of 41.
Use 7 as the next digit of our solution. 
Result so far: 11647.14035087
If we subtract 399 from 440, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

After the division, we end up with 11647.14035087 and a remainder of 4.1e-08.
