99210198 ÷ 206 
Our goal is to divide 99210198 by 206.

Let's proceed to step 1:
9 divided by 206 is 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 206

Moving on to step 2:
206 goes into 99 0 times with a remainder of 99.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 99, we end up with 99.
Take the next digit (2) from the dividend and append it to 99, then repeat: 992 / 206

Advancing to step 3:
If we divide 992 by 206, we get 4 and a remainder of 168.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtract 824 from 992 to get 168.
Append the next digit (1) from the dividend to 168 and continue with: 1681 / 206

Let's proceed to step 4:
When dividing 1681 by 206, we get 8 with a remainder of 33.
Record the quotient 8 as the next digit in the result. 
Result so far: 48.0
Subtracting 1648 from 1681 leaves us with 33.
Fetch the next digit (0) from the dividend, attach it to 33 and continue: 330 / 206

Let's proceed to step 5:
206 can be fit into 330 1 times, resulting in a remainder of 124.
Put 1 as the next digit of the answer. 
Result so far: 481.0
Deduct 206 from 330 and we're left with 124.
Take the next digit (1) from the dividend and append it to 124, then repeat: 1241 / 206

On to step 6:
The number 206 fits into 1241 6 times, leaving a remainder of 5.
The next digit of our result is 6. 
Result so far: 4816.0
The remainder is 5 after subtracting 1236 from 1241.
Append the next digit (9) from the dividend to 5 and continue with: 59 / 206

Let's proceed to step 7:
If we divide 59 by 206, we get 0 and a remainder of 59.
The number 0 becomes the next digit in our result. 
Result so far: 48160.0
Subtract 0 from 59 to get 59.
Grab the next digit (8) from the dividend, add it to 59, then carry on: 598 / 206

Going ahead to step 8:
206 goes into 598 2 times with a remainder of 186.
Record the quotient 2 as the next digit in the result. 
Result so far: 481602.0
Subtracting 412 from 598 leaves us with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Step 9:
If we divide 1860 by 206, we get 9 and a remainder of 6.
Write down 9 as next digit of the result. 
Result so far: 481602.9
The remainder is 6 after subtracting 1854 from 1860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 10:
60 divided by 206 is 0 with a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 481602.9
Subtracting 0 from 60 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 11:
206 goes into 600 2 times with a remainder of 188.
The number 2 becomes the next digit in our result. 
Result so far: 481602.902
Subtract 412 from 600 to get 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Going ahead to step 12:
206 goes into 1880 9 times with a remainder of 26.
Put 9 as the next digit of the answer. 
Result so far: 481602.9029
The remainder is 26 after subtracting 1854 from 1880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 13:
206 goes into 260 1 times with a remainder of 54.
Put 1 as the next digit of the answer. 
Result so far: 481602.90291
If we subtract 206 from 260, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 14:
206 goes into 540 2 times with a remainder of 128.
Write down 2 as next digit of the result. 
Result so far: 481602.902912
Deduct 412 from 540 and we're left with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Let's proceed to step 15:
The number 206 fits into 1280 6 times, leaving a remainder of 44.
Use 6 as the next digit of our solution. 
Result so far: 481602.9029126
If we take 1236 away from 1280, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 16:
The number 206 fits into 440 2 times, leaving a remainder of 28.
Write down 2 as next digit of the result. 
Result so far: 481602.90291262
Deduct 412 from 440 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

After the division, we end up with 481602.90291262 and a remainder of 2.8e-08.
