57521570 divided by 166 
Our goal is to divide 57521570 by 166.

Advancing to step 1:
When dividing 5 by 166, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 166

Going ahead to step 2:
The number 166 fits into 57 0 times, leaving a remainder of 57.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 57 after subtracting 0 from 57.
Grab the next digit (5) from the dividend, add it to 57, then carry on: 575 / 166

Moving on to step 3:
The number 166 fits into 575 3 times, leaving a remainder of 77.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 498 away from 575, we end up with 77.
Grab the next digit (2) from the dividend, add it to 77, then carry on: 772 / 166

On to step 4:
When dividing 772 by 166, we get 4 with a remainder of 108.
The number 4 becomes the next digit in our result. 
Result so far: 34.0
If we take 664 away from 772, we end up with 108.
Grab the next digit (1) from the dividend, add it to 108, then carry on: 1081 / 166

Let's proceed to step 5:
When dividing 1081 by 166, we get 6 with a remainder of 85.
Write down 6 as next digit of the result. 
Result so far: 346.0
If we take 996 away from 1081, we end up with 85.
Bring next digit (5) of the dividend behind the 85 and repeat the process: 855 / 166

Advancing to step 6:
166 goes into 855 5 times with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 3465.0
Deduct 830 from 855 and we're left with 25.
Grab the next digit (7) from the dividend, add it to 25, then carry on: 257 / 166

Moving on to step 7:
When dividing 257 by 166, we get 1 with a remainder of 91.
Write down 1 as next digit of the result. 
Result so far: 34651.0
Subtract 166 from 257 to get 91.
Take the next digit (0) from the dividend and append it to 91, then repeat: 910 / 166

Moving on to step 8:
166 can be fit into 910 5 times, resulting in a remainder of 80.
The next digit of our result is 5. 
Result so far: 346515.0
Subtract 830 from 910 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 9:
The number 166 fits into 800 4 times, leaving a remainder of 136.
Write down 4 as next digit of the result. 
Result so far: 346515.4
Subtract 664 from 800 to get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Step 10:
1360 divided by 166 is 8 with a remainder of 32.
Write down 8 as next digit of the result. 
Result so far: 346515.48
The remainder is 32 after subtracting 1328 from 1360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 11:
166 goes into 320 1 times with a remainder of 154.
Put 1 as the next digit of the answer. 
Result so far: 346515.481
Subtracting 166 from 320 leaves us with 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Let's proceed to step 12:
166 can be fit into 1540 9 times, resulting in a remainder of 46.
Write down 9 as next digit of the result. 
Result so far: 346515.4819
Subtracting 1494 from 1540 leaves us 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 13:
166 can be fit into 460 2 times, resulting in a remainder of 128.
The next digit of our result is 2. 
Result so far: 346515.48192
If we take 332 away from 460, we end up with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Advancing to step 14:
If we divide 1280 by 166, we get 7 and a remainder of 118.
Use 7 as the next digit of our solution. 
Result so far: 346515.481927
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.

Going ahead to step 15:
The number 166 fits into 1180 7 times, leaving a remainder of 18.
Put 7 as the next digit of the answer. 
Result so far: 346515.4819277
If we take 1162 away from 1180, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The final result is 346515.4819277 with a remainder of 1.8e-07.
