57839534 ÷ 166 
We want to divide 57839534 by 166.

On to step 1:
The number 166 fits into 5 0 times, leaving a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 166

Going ahead to step 2:
166 goes into 57 0 times with a remainder of 57.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 57 and we're left with 57.
Bring next digit (8) of the dividend behind the 57 and repeat the process: 578 / 166

Moving on to step 3:
578 divided by 166 is 3 with a remainder of 80.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 498 from 578, we get 80.
Grab the next digit (3) from the dividend, add it to 80, then carry on: 803 / 166

Step 4:
When dividing 803 by 166, we get 4 with a remainder of 139.
The next digit of our result is 4. 
Result so far: 34.0
Subtracting 664 from 803 leaves us with 139.
Include the next digit (9) from the dividend after 139, then repeat: 1399 / 166

Let's proceed to step 5:
If we divide 1399 by 166, we get 8 and a remainder of 71.
Use 8 as the next digit of our solution. 
Result so far: 348.0
Subtract 1328 from 1399 to get 71.
Take the next digit (5) from the dividend and append it to 71, then repeat: 715 / 166

Step 6:
The number 166 fits into 715 4 times, leaving a remainder of 51.
Write down 4 as next digit of the result. 
Result so far: 3484.0
Subtracting 664 from 715 leaves us with 51.
Bring next digit (3) of the dividend behind the 51 and repeat the process: 513 / 166

Going ahead to step 7:
166 goes into 513 3 times with a remainder of 15.
The next digit of our result is 3. 
Result so far: 34843.0
If we subtract 498 from 513, we get 15.
Include the next digit (4) from the dividend after 15, then repeat: 154 / 166

Advancing to step 8:
The number 166 fits into 154 0 times, leaving a remainder of 154.
Write down 0 as next digit of the result. 
Result so far: 348430.0
The remainder is 154 after subtracting 0 from 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Step 9:
If we divide 1540 by 166, we get 9 and a remainder of 46.
Record the quotient 9 as the next digit in the result. 
Result so far: 348430.9
The remainder is 46 after subtracting 1494 from 1540.
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 10:
166 goes into 460 2 times with a remainder of 128.
The next digit of our result is 2. 
Result so far: 348430.92
If we subtract 332 from 460, we get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Let's proceed to step 11:
166 goes into 1280 7 times with a remainder of 118.
Put 7 as the next digit of the answer. 
Result so far: 348430.927
Subtract 1162 from 1280 to get 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Step 12:
166 goes into 1180 7 times with a remainder of 18.
Put 7 as the next digit of the answer. 
Result so far: 348430.9277
Subtract 1162 from 1180 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

In conclusion, the division gives 348430.9277 with a balance of 0.00018.
