173488 ÷ 57 
We're looking to find how many times 57 goes into 173488.

Step 1:
57 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 57

On to step 2:
If we divide 17 by 57, we get 0 and a remainder of 17.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 17 leaves us with 17.
Fetch the next digit (3) from the dividend, attach it to 17 and continue: 173 / 57

Going ahead to step 3:
The number 57 fits into 173 3 times, leaving a remainder of 2.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 171 from 173 and we're left with 2.
Append the next digit (4) from the dividend to 2 and continue with: 24 / 57

On to step 4:
If we divide 24 by 57, we get 0 and a remainder of 24.
Write down 0 as next digit of the result. 
Result so far: 30.0
Subtract 0 from 24 to get 24.
Append the next digit (8) from the dividend to 24 and continue with: 248 / 57

Advancing to step 5:
57 can be fit into 248 4 times, resulting in a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 304.0
Subtract 228 from 248 to get 20.
Fetch the next digit (8) from the dividend, attach it to 20 and continue: 208 / 57

Moving on to step 6:
57 goes into 208 3 times with a remainder of 37.
Write down 3 as next digit of the result. 
Result so far: 3043.0
If we subtract 171 from 208, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 7:
370 divided by 57 is 6 with a remainder of 28.
The next digit of our result is 6. 
Result so far: 3043.6
If we subtract 342 from 370, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 8:
If we divide 280 by 57, we get 4 and a remainder of 52.
Put 4 as the next digit of the answer. 
Result so far: 3043.64
Deduct 228 from 280 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 9:
When dividing 520 by 57, we get 9 with a remainder of 7.
Record the quotient 9 as the next digit in the result. 
Result so far: 3043.649
The remainder is 7 after subtracting 513 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 10:
70 divided by 57 is 1 with a remainder of 13.
The next digit of our result is 1. 
Result so far: 3043.6491
Subtract 57 from 70 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 11:
130 divided by 57 is 2 with a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 3043.64912
Deduct 114 from 130 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 12:
160 divided by 57 is 2 with a remainder of 46.
The number 2 becomes the next digit in our result. 
Result so far: 3043.649122
Subtract 114 from 160 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

In conclusion, the division gives 3043.649122 with a balance of 4.6e-06.
