We look at the division of 81739590 by 206 
We want to figure out the number of times 81739590 can be divided by 206.

Let's proceed to step 1:
The number 206 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 206

Going ahead to step 2:
81 divided by 206 is 0 with a remainder of 81.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 81, we get 81.
Fetch the next digit (7) from the dividend, attach it to 81 and continue: 817 / 206

Step 3:
817 divided by 206 is 3 with a remainder of 199.
The next digit of our result is 3. 
Result so far: 3.0
The remainder is 199 after subtracting 618 from 817.
Take the next digit (3) from the dividend and append it to 199, then repeat: 1993 / 206

Going ahead to step 4:
206 goes into 1993 9 times with a remainder of 139.
Record the quotient 9 as the next digit in the result. 
Result so far: 39.0
Deduct 1854 from 1993 and we're left with 139.
Bring next digit (9) of the dividend behind the 139 and repeat the process: 1399 / 206

Going ahead to step 5:
When dividing 1399 by 206, we get 6 with a remainder of 163.
The number 6 becomes the next digit in our result. 
Result so far: 396.0
Subtracting 1236 from 1399 leaves us with 163.
Take the next digit (5) from the dividend and append it to 163, then repeat: 1635 / 206

On to step 6:
206 can be fit into 1635 7 times, resulting in a remainder of 193.
Use 7 as the next digit of our solution. 
Result so far: 3967.0
If we take 1442 away from 1635, we end up with 193.
Bring next digit (9) of the dividend behind the 193 and repeat the process: 1939 / 206

Moving on to step 7:
206 goes into 1939 9 times with a remainder of 85.
Put 9 as the next digit of the answer. 
Result so far: 39679.0
The remainder is 85 after subtracting 1854 from 1939.
Include the next digit (0) from the dividend after 85, then repeat: 850 / 206

Let's proceed to step 8:
206 can be fit into 850 4 times, resulting in a remainder of 26.
Record the quotient 4 as the next digit in the result. 
Result so far: 396794.0
If we subtract 824 from 850, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 9:
206 goes into 260 1 times with a remainder of 54.
The number 1 becomes the next digit in our result. 
Result so far: 396794.1
If we take 206 away from 260, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 10:
If we divide 540 by 206, we get 2 and a remainder of 128.
Record the quotient 2 as the next digit in the result. 
Result so far: 396794.12
If we subtract 412 from 540, we get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Moving on to step 11:
1280 divided by 206 is 6 with a remainder of 44.
Record the quotient 6 as the next digit in the result. 
Result so far: 396794.126
Subtracting 1236 from 1280 leaves us 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 12:
When dividing 440 by 206, we get 2 with a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 396794.1262
Subtract 412 from 440 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 13:
When dividing 280 by 206, we get 1 with a remainder of 74.
The number 1 becomes the next digit in our result. 
Result so far: 396794.12621
Deduct 206 from 280 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Going ahead to step 14:
When dividing 740 by 206, we get 3 with a remainder of 122.
The number 3 becomes the next digit in our result. 
Result so far: 396794.126213
Deduct 618 from 740 and we're left with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

On to step 15:
1220 divided by 206 is 5 with a remainder of 190.
Put 5 as the next digit of the answer. 
Result so far: 396794.1262135
Subtract 1030 from 1220 to get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

On to step 16:
1900 divided by 206 is 9 with a remainder of 46.
Write down 9 as next digit of the result. 
Result so far: 396794.12621359
If we subtract 1854 from 1900, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

After the division, we end up with 396794.12621359 and a remainder of 4.6e-08.
