147399 ÷ 57 
We're looking to find how many times 57 goes into 147399.

On to step 1:
The number 57 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 57

Moving on to step 2:
The number 57 fits into 14 0 times, leaving a remainder of 14.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 14, we get 14.
Take the next digit (7) from the dividend and append it to 14, then repeat: 147 / 57

Moving on to step 3:
57 goes into 147 2 times with a remainder of 33.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 114 from 147 and we're left with 33.
Append the next digit (3) from the dividend to 33 and continue with: 333 / 57

Going ahead to step 4:
If we divide 333 by 57, we get 5 and a remainder of 48.
The next digit of our result is 5. 
Result so far: 25.0
Deduct 285 from 333 and we're left with 48.
Fetch the next digit (9) from the dividend, attach it to 48 and continue: 489 / 57

Let's proceed to step 5:
57 can be fit into 489 8 times, resulting in a remainder of 33.
The next digit of our result is 8. 
Result so far: 258.0
If we take 456 away from 489, we end up with 33.
Fetch the next digit (9) from the dividend, attach it to 33 and continue: 339 / 57

Moving on to step 6:
If we divide 339 by 57, we get 5 and a remainder of 54.
Write down 5 as next digit of the result. 
Result so far: 2585.0
If we take 285 away from 339, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 7:
540 divided by 57 is 9 with a remainder of 27.
Write down 9 as next digit of the result. 
Result so far: 2585.9
Subtract 513 from 540 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 8:
The number 57 fits into 270 4 times, leaving a remainder of 42.
Put 4 as the next digit of the answer. 
Result so far: 2585.94
Subtracting 228 from 270 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 9:
When dividing 420 by 57, we get 7 with a remainder of 21.
Put 7 as the next digit of the answer. 
Result so far: 2585.947
The remainder is 21 after subtracting 399 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 10:
The number 57 fits into 210 3 times, leaving a remainder of 39.
The next digit of our result is 3. 
Result so far: 2585.9473
Deduct 171 from 210 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 11:
57 can be fit into 390 6 times, resulting in a remainder of 48.
Use 6 as the next digit of our solution. 
Result so far: 2585.94736
Subtract 342 from 390 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 12:
The number 57 fits into 480 8 times, leaving a remainder of 24.
Use 8 as the next digit of our solution. 
Result so far: 2585.947368
If we subtract 456 from 480, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 13:
57 goes into 240 4 times with a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 2585.9473684
If we subtract 228 from 240, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 14:
57 goes into 120 2 times with a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 2585.94736842
If we take 114 away from 120, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The final result is 2585.94736842 with a remainder of 6e-09.
