43879 ÷ 57 
We want to figure out the number of times 43879 can be divided by 57.

Advancing to step 1:
If we divide 4 by 57, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 57

Going ahead to step 2:
When dividing 43 by 57, we get 0 with a remainder of 43.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 43 to get 43.
Append the next digit (8) from the dividend to 43 and continue with: 438 / 57

Going ahead to step 3:
When dividing 438 by 57, we get 7 with a remainder of 39.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we subtract 399 from 438, we get 39.
Append the next digit (7) from the dividend to 39 and continue with: 397 / 57

Moving on to step 4:
If we divide 397 by 57, we get 6 and a remainder of 55.
Put 6 as the next digit of the answer. 
Result so far: 76.0
If we take 342 away from 397, we end up with 55.
Grab the next digit (9) from the dividend, add it to 55, then carry on: 559 / 57

Step 5:
57 can be fit into 559 9 times, resulting in a remainder of 46.
The number 9 becomes the next digit in our result. 
Result so far: 769.0
If we take 513 away from 559, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 6:
57 can be fit into 460 8 times, resulting in a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 769.8
If we subtract 456 from 460, we 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 7:
57 can be fit into 40 0 times, resulting in a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 769.8
Deduct 0 from 40 and we're left 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 8:
57 goes into 400 7 times with a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 769.807
Subtract 399 from 400 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 9:
The number 57 fits into 10 0 times, leaving a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 769.807
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 10:
If we divide 100 by 57, we get 1 and a remainder of 43.
Record the quotient 1 as the next digit in the result. 
Result so far: 769.80701
If we take 57 away from 100, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 11:
57 goes into 430 7 times with a remainder of 31.
Put 7 as the next digit of the answer. 
Result so far: 769.807017
Subtracting 399 from 430 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 12:
The number 57 fits into 310 5 times, leaving a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 769.8070175
Subtract 285 from 310 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 13:
When dividing 250 by 57, we get 4 with a remainder of 22.
Put 4 as the next digit of the answer. 
Result so far: 769.80701754
Deduct 228 from 250 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.

The quotient of the division is 769.80701754, and the remainder is 2.2e-08.
