We divide 161800 by 89
We're looking to find how many times 89 goes into 161800.

Let's proceed to step 1:
89 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 89

Moving on to step 2:
16 divided by 89 is 0 with a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 16, we end up with 16.
Bring next digit (1) of the dividend behind the 16 and repeat the process: 161 / 89

Going ahead to step 3:
89 can be fit into 161 1 times, resulting in a remainder of 72.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 89 from 161 to get 72.
Bring next digit (8) of the dividend behind the 72 and repeat the process: 728 / 89

Let's proceed to step 4:
The number 89 fits into 728 8 times, leaving a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 18.0
Deduct 712 from 728 and we're left with 16.
Append the next digit (0) from the dividend to 16 and continue with: 160 / 89

Advancing to step 5:
If we divide 160 by 89, we get 1 and a remainder of 71.
Put 1 as the next digit of the answer. 
Result so far: 181.0
Deduct 89 from 160 and we're left with 71.
Append the next digit (0) from the dividend to 71 and continue with: 710 / 89

On to step 6:
The number 89 fits into 710 7 times, leaving a remainder of 87.
Use 7 as the next digit of our solution. 
Result so far: 1817.0
Subtract 623 from 710 to get 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Advancing to step 7:
89 can be fit into 870 9 times, resulting in a remainder of 69.
The number 9 becomes the next digit in our result. 
Result so far: 1817.9
Subtract 801 from 870 to get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

On to step 8:
If we divide 690 by 89, we get 7 and a remainder of 67.
Use 7 as the next digit of our solution. 
Result so far: 1817.97
If we take 623 away from 690, we end up with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Step 9:
670 divided by 89 is 7 with a remainder of 47.
Use 7 as the next digit of our solution. 
Result so far: 1817.977
The remainder is 47 after subtracting 623 from 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

The final result is 1817.977 with a remainder of 0.0047.
