We're dividing 53181740 by 166 
Let's see how many times 166 fits into 53181740.

Advancing to step 1:
When dividing 5 by 166, we get 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 166

Moving on to step 2:
166 goes into 53 0 times with a remainder of 53.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 53, we end up with 53.
Fetch the next digit (1) from the dividend, attach it to 53 and continue: 531 / 166

On to step 3:
If we divide 531 by 166, we get 3 and a remainder of 33.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 33 after subtracting 498 from 531.
Fetch the next digit (8) from the dividend, attach it to 33 and continue: 338 / 166

Going ahead to step 4:
166 goes into 338 2 times with a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 32.0
Deduct 332 from 338 and we're left with 6.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 166

Moving on to step 5:
When dividing 61 by 166, we get 0 with a remainder of 61.
Write down 0 as next digit of the result. 
Result so far: 320.0
Deduct 0 from 61 and we're left with 61.
Append the next digit (7) from the dividend to 61 and continue with: 617 / 166

Let's proceed to step 6:
The number 166 fits into 617 3 times, leaving a remainder of 119.
Record the quotient 3 as the next digit in the result. 
Result so far: 3203.0
The remainder is 119 after subtracting 498 from 617.
Bring next digit (4) of the dividend behind the 119 and repeat the process: 1194 / 166

Step 7:
The number 166 fits into 1194 7 times, leaving a remainder of 32.
The number 7 becomes the next digit in our result. 
Result so far: 32037.0
Subtracting 1162 from 1194 leaves us with 32.
Fetch the next digit (0) from the dividend, attach it to 32 and continue: 320 / 166

Step 8:
166 goes into 320 1 times with a remainder of 154.
Use 1 as the next digit of our solution. 
Result so far: 320371.0
If we subtract 166 from 320, we get 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Moving on to step 9:
166 goes into 1540 9 times with a remainder of 46.
Write down 9 as next digit of the result. 
Result so far: 320371.9
If we take 1494 away from 1540, 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 10:
166 goes into 460 2 times with a remainder of 128.
Use 2 as the next digit of our solution. 
Result so far: 320371.92
The remainder is 128 after subtracting 332 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Going ahead to step 11:
1280 divided by 166 is 7 with a remainder of 118.
The next digit of our result is 7. 
Result so far: 320371.927
Deduct 1162 from 1280 and we're left with 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Let's proceed to step 12:
166 goes into 1180 7 times with a remainder of 18.
Record the quotient 7 as the next digit in the result. 
Result so far: 320371.9277
Subtracting 1162 from 1180 leaves us 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 quotient of the division is 320371.9277, and the remainder is 0.00018.
