We divide 169643 by 89
We want to figure out the number of times 169643 can be divided by 89.

Going ahead to step 1:
89 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
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 / 89

Advancing to step 2:
When dividing 16 by 89, we get 0 with a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 16 leaves us with 16.
Fetch the next digit (9) from the dividend, attach it to 16 and continue: 169 / 89

Step 3:
169 divided by 89 is 1 with a remainder of 80.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 80 after subtracting 89 from 169.
Append the next digit (6) from the dividend to 80 and continue with: 806 / 89

Step 4:
If we divide 806 by 89, we get 9 and a remainder of 5.
Put 9 as the next digit of the answer. 
Result so far: 19.0
Subtracting 801 from 806 leaves us with 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 89

Advancing to step 5:
89 can be fit into 54 0 times, resulting in a remainder of 54.
Write down 0 as next digit of the result. 
Result so far: 190.0
Subtracting 0 from 54 leaves us with 54.
Grab the next digit (3) from the dividend, add it to 54, then carry on: 543 / 89

Step 6:
If we divide 543 by 89, we get 6 and a remainder of 9.
The number 6 becomes the next digit in our result. 
Result so far: 1906.0
Deduct 534 from 543 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.

Advancing to step 7:
89 can be fit into 90 1 times, resulting in a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 1906.1
If we take 89 away from 90, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 8:
89 goes into 10 0 times with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 1906.1
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 9:
If we divide 100 by 89, we get 1 and a remainder of 11.
The next digit of our result is 1. 
Result so far: 1906.101
If we subtract 89 from 100, we 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.

Moving on to step 10:
89 goes into 110 1 times with a remainder of 21.
Write down 1 as next digit of the result. 
Result so far: 1906.1011
Deduct 89 from 110 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

The final result is 1906.1011 with a remainder of 0.00021.
