89519819 ÷ 206 
Our goal is to divide 89519819 by 206.

Step 1:
206 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (9) from the dividend after 8, then repeat: 89 / 206

Moving on to step 2:
206 goes into 89 0 times with a remainder of 89.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 89, we end up with 89.
Append the next digit (5) from the dividend to 89 and continue with: 895 / 206

Step 3:
If we divide 895 by 206, we get 4 and a remainder of 71.
The next digit of our result is 4. 
Result so far: 4.0
If we subtract 824 from 895, we get 71.
Fetch the next digit (1) from the dividend, attach it to 71 and continue: 711 / 206

Moving on to step 4:
If we divide 711 by 206, we get 3 and a remainder of 93.
Write down 3 as next digit of the result. 
Result so far: 43.0
If we subtract 618 from 711, we get 93.
Fetch the next digit (9) from the dividend, attach it to 93 and continue: 939 / 206

Advancing to step 5:
The number 206 fits into 939 4 times, leaving a remainder of 115.
The number 4 becomes the next digit in our result. 
Result so far: 434.0
If we take 824 away from 939, we end up with 115.
Include the next digit (8) from the dividend after 115, then repeat: 1158 / 206

Moving on to step 6:
The number 206 fits into 1158 5 times, leaving a remainder of 128.
Use 5 as the next digit of our solution. 
Result so far: 4345.0
If we subtract 1030 from 1158, we get 128.
Append the next digit (1) from the dividend to 128 and continue with: 1281 / 206

Moving on to step 7:
When dividing 1281 by 206, we get 6 with a remainder of 45.
Put 6 as the next digit of the answer. 
Result so far: 43456.0
Deduct 1236 from 1281 and we're left with 45.
Take the next digit (9) from the dividend and append it to 45, then repeat: 459 / 206

Moving on to step 8:
459 divided by 206 is 2 with a remainder of 47.
The next digit of our result is 2. 
Result so far: 434562.0
If we take 412 away from 459, we end up with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Step 9:
When dividing 470 by 206, we get 2 with a remainder of 58.
The next digit of our result is 2. 
Result so far: 434562.2
If we take 412 away from 470, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 10:
580 divided by 206 is 2 with a remainder of 168.
Write down 2 as next digit of the result. 
Result so far: 434562.22
If we subtract 412 from 580, we get 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Our division results in 434562.22 with a remaining 0.168.
