643286 divided by 57 
Our goal is to divide 643286 by 57.

Going ahead to step 1:
The number 57 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 57

Moving on to step 2:
When dividing 64 by 57, we get 1 with a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 57 from 64 to get 7.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 57

Moving on to step 3:
73 divided by 57 is 1 with a remainder of 16.
Write down 1 as next digit of the result. 
Result so far: 11.0
If we subtract 57 from 73, we get 16.
Bring next digit (2) of the dividend behind the 16 and repeat the process: 162 / 57

On to step 4:
162 divided by 57 is 2 with a remainder of 48.
The next digit of our result is 2. 
Result so far: 112.0
Subtract 114 from 162 to get 48.
Append the next digit (8) from the dividend to 48 and continue with: 488 / 57

Let's proceed to step 5:
The number 57 fits into 488 8 times, leaving a remainder of 32.
Use 8 as the next digit of our solution. 
Result so far: 1128.0
If we take 456 away from 488, we end up with 32.
Grab the next digit (6) from the dividend, add it to 32, then carry on: 326 / 57

Advancing to step 6:
The number 57 fits into 326 5 times, leaving a remainder of 41.
Write down 5 as next digit of the result. 
Result so far: 11285.0
If we subtract 285 from 326, 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.

Going ahead to step 7:
57 goes into 410 7 times with a remainder of 11.
Use 7 as the next digit of our solution. 
Result so far: 11285.7
The remainder is 11 after subtracting 399 from 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 8:
The number 57 fits into 110 1 times, leaving a remainder of 53.
Write down 1 as next digit of the result. 
Result so far: 11285.71
Subtract 57 from 110 to get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Advancing to step 9:
57 goes into 530 9 times with a remainder of 17.
Put 9 as the next digit of the answer. 
Result so far: 11285.719
The remainder is 17 after subtracting 513 from 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 10:
57 goes into 170 2 times with a remainder of 56.
The next digit of our result is 2. 
Result so far: 11285.7192
Subtract 114 from 170 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 11:
560 divided by 57 is 9 with a remainder of 47.
The number 9 becomes the next digit in our result. 
Result so far: 11285.71929
Subtract 513 from 560 to get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Moving on to step 12:
If we divide 470 by 57, we get 8 and a remainder of 14.
Write down 8 as next digit of the result. 
Result so far: 11285.719298
Deduct 456 from 470 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 13:
57 can be fit into 140 2 times, resulting in a remainder of 26.
Write down 2 as next digit of the result. 
Result so far: 11285.7192982
Deduct 114 from 140 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 14:
If we divide 260 by 57, we get 4 and a remainder of 32.
The number 4 becomes the next digit in our result. 
Result so far: 11285.71929824
Deduct 228 from 260 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The quotient of the division is 11285.71929824, and the remainder is 3.2e-08.
