Our goal is to divide 21887633 by 166.

Advancing to step 1:
2 divided by 166 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 166

Let's proceed to step 2:
21 divided by 166 is 0 with a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Include the next digit (8) from the dividend after 21, then repeat: 218 / 166

Moving on to step 3:
166 goes into 218 1 times with a remainder of 52.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 166 from 218, we get 52.
Bring next digit (8) of the dividend behind the 52 and repeat the process: 528 / 166

On to step 4:
166 goes into 528 3 times with a remainder of 30.
Put 3 as the next digit of the answer. 
Result so far: 13.0
The remainder is 30 after subtracting 498 from 528.
Append the next digit (7) from the dividend to 30 and continue with: 307 / 166

Step 5:
The number 166 fits into 307 1 times, leaving a remainder of 141.
Write down 1 as next digit of the result. 
Result so far: 131.0
Subtract 166 from 307 to get 141.
Grab the next digit (6) from the dividend, add it to 141, then carry on: 1416 / 166

Moving on to step 6:
166 can be fit into 1416 8 times, resulting in a remainder of 88.
Write down 8 as next digit of the result. 
Result so far: 1318.0
The remainder is 88 after subtracting 1328 from 1416.
Bring next digit (3) of the dividend behind the 88 and repeat the process: 883 / 166

Advancing to step 7:
The number 166 fits into 883 5 times, leaving a remainder of 53.
Put 5 as the next digit of the answer. 
Result so far: 13185.0
If we subtract 830 from 883, we get 53.
Grab the next digit (3) from the dividend, add it to 53, then carry on: 533 / 166

Going ahead to step 8:
166 can be fit into 533 3 times, resulting in a remainder of 35.
Write down 3 as next digit of the result. 
Result so far: 131853.0
The remainder is 35 after subtracting 498 from 533.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 9:
The number 166 fits into 350 2 times, leaving a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 131853.2
The remainder is 18 after subtracting 332 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 10:
180 divided by 166 is 1 with a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 131853.21
Deduct 166 from 180 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 11:
When dividing 140 by 166, we get 0 with a remainder of 140.
Record the quotient 0 as the next digit in the result. 
Result so far: 131853.21
Subtract 0 from 140 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Step 12:
When dividing 1400 by 166, we get 8 with a remainder of 72.
Put 8 as the next digit of the answer. 
Result so far: 131853.2108
Deduct 1328 from 1400 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 13:
720 divided by 166 is 4 with a remainder of 56.
Use 4 as the next digit of our solution. 
Result so far: 131853.21084
If we subtract 664 from 720, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 14:
166 can be fit into 560 3 times, resulting in a remainder of 62.
Write down 3 as next digit of the result. 
Result so far: 131853.210843
The remainder is 62 after subtracting 498 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 15:
The number 166 fits into 620 3 times, leaving a remainder of 122.
The next digit of our result is 3. 
Result so far: 131853.2108433
Subtract 498 from 620 to get 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

The final outcome is 131853.2108433, with a leftover of 1.22e-06.
