163690 ÷ 91 
Let's see how many times 91 fits into 163690.

Going ahead to step 1:
When dividing 1 by 91, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 91

On to step 2:
When dividing 16 by 91, we get 0 with a remainder of 16.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 16 and we're left with 16.
Bring next digit (3) of the dividend behind the 16 and repeat the process: 163 / 91

Let's proceed to step 3:
If we divide 163 by 91, we get 1 and a remainder of 72.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 91 from 163 to get 72.
Fetch the next digit (6) from the dividend, attach it to 72 and continue: 726 / 91

Moving on to step 4:
When dividing 726 by 91, we get 7 with a remainder of 89.
The next digit of our result is 7. 
Result so far: 17.0
Deduct 637 from 726 and we're left with 89.
Include the next digit (9) from the dividend after 89, then repeat: 899 / 91

On to step 5:
If we divide 899 by 91, we get 9 and a remainder of 80.
Use 9 as the next digit of our solution. 
Result so far: 179.0
Subtract 819 from 899 to get 80.
Grab the next digit (0) from the dividend, add it to 80, then carry on: 800 / 91

Let's proceed to step 6:
The number 91 fits into 800 8 times, leaving a remainder of 72.
The number 8 becomes the next digit in our result. 
Result so far: 1798.0
Subtract 728 from 800 to get 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 7:
91 goes into 720 7 times with a remainder of 83.
Record the quotient 7 as the next digit in the result. 
Result so far: 1798.7
If we subtract 637 from 720, we get 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Step 8:
830 divided by 91 is 9 with a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 1798.79
The remainder is 11 after subtracting 819 from 830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 9:
When dividing 110 by 91, we get 1 with a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 1798.791
If we subtract 91 from 110, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 10:
The number 91 fits into 190 2 times, leaving a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 1798.7912
If we subtract 182 from 190, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 11:
80 divided by 91 is 0 with a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 1798.7912
The remainder is 80 after subtracting 0 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 12:
800 divided by 91 is 8 with a remainder of 72.
The number 8 becomes the next digit in our result. 
Result so far: 1798.791208
If we take 728 away from 800, we end up 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.

On to step 13:
91 can be fit into 720 7 times, resulting in a remainder of 83.
Record the quotient 7 as the next digit in the result. 
Result so far: 1798.7912087
If we take 637 away from 720, we end up with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

On to step 14:
91 goes into 830 9 times with a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 1798.79120879
Subtract 819 from 830 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

After the division, we end up with 1798.79120879 and a remainder of 1.1e-08.
