We're dividing 168991 by 11 
Our goal is to divide 168991 by 11.

On to step 1:
If we divide 1 by 11, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 11

On to step 2:
The number 11 fits into 16 1 times, leaving a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 11 from 16 and we're left with 5.
Append the next digit (8) from the dividend to 5 and continue with: 58 / 11

Step 3:
When dividing 58 by 11, we get 5 with a remainder of 3.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
If we subtract 55 from 58, we get 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 11

Going ahead to step 4:
If we divide 39 by 11, we get 3 and a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 153.0
Subtracting 33 from 39 leaves us with 6.
Take the next digit (9) from the dividend and append it to 6, then repeat: 69 / 11

On to step 5:
11 goes into 69 6 times with a remainder of 3.
The number 6 becomes the next digit in our result. 
Result so far: 1536.0
Deduct 66 from 69 and we're left with 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 11

Advancing to step 6:
The number 11 fits into 31 2 times, leaving a remainder of 9.
Put 2 as the next digit of the answer. 
Result so far: 15362.0
If we subtract 22 from 31, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 7:
11 can be fit into 90 8 times, resulting in a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 15362.8
The remainder is 2 after subtracting 88 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 8:
If we divide 20 by 11, we get 1 and a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 15362.81
Deduct 11 from 20 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 9:
The number 11 fits into 90 8 times, leaving a remainder of 2.
The next digit of our result is 8. 
Result so far: 15362.818
Deduct 88 from 90 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 10:
11 can be fit into 20 1 times, resulting in a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 15362.8181
Subtracting 11 from 20 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 11:
11 can be fit into 90 8 times, resulting in a remainder of 2.
The next digit of our result is 8. 
Result so far: 15362.81818
Subtract 88 from 90 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 12:
The number 11 fits into 20 1 times, leaving a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 15362.818181
If we take 11 away from 20, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 13:
When dividing 90 by 11, we get 8 with a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 15362.8181818
If we take 88 away from 90, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 14:
If we divide 20 by 11, we get 1 and a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 15362.81818181
If we take 11 away from 20, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

The final outcome is 15362.81818181, with a leftover of 9e-09.
