71597891 ÷ 206 
We want to divide 71597891 by 206.

On to step 1:
206 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 206

Moving on to step 2:
If we divide 71 by 206, we get 0 and a remainder of 71.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 71 to get 71.
Take the next digit (5) from the dividend and append it to 71, then repeat: 715 / 206

On to step 3:
The number 206 fits into 715 3 times, leaving a remainder of 97.
The next digit of our result is 3. 
Result so far: 3.0
Subtracting 618 from 715 leaves us with 97.
Append the next digit (9) from the dividend to 97 and continue with: 979 / 206

Going ahead to step 4:
206 can be fit into 979 4 times, resulting in a remainder of 155.
The number 4 becomes the next digit in our result. 
Result so far: 34.0
Subtracting 824 from 979 leaves us with 155.
Take the next digit (7) from the dividend and append it to 155, then repeat: 1557 / 206

Going ahead to step 5:
If we divide 1557 by 206, we get 7 and a remainder of 115.
The next digit of our result is 7. 
Result so far: 347.0
Deduct 1442 from 1557 and we're left with 115.
Include the next digit (8) from the dividend after 115, then repeat: 1158 / 206

Advancing to step 6:
The number 206 fits into 1158 5 times, leaving a remainder of 128.
The number 5 becomes the next digit in our result. 
Result so far: 3475.0
If we take 1030 away from 1158, we end up with 128.
Include the next digit (9) from the dividend after 128, then repeat: 1289 / 206

Step 7:
206 goes into 1289 6 times with a remainder of 53.
The number 6 becomes the next digit in our result. 
Result so far: 34756.0
Subtract 1236 from 1289 to get 53.
Take the next digit (1) from the dividend and append it to 53, then repeat: 531 / 206

Step 8:
531 divided by 206 is 2 with a remainder of 119.
Put 2 as the next digit of the answer. 
Result so far: 347562.0
If we subtract 412 from 531, we get 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Let's proceed to step 9:
206 can be fit into 1190 5 times, resulting in a remainder of 160.
The number 5 becomes the next digit in our result. 
Result so far: 347562.5
Deduct 1030 from 1190 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 10:
When dividing 1600 by 206, we get 7 with a remainder of 158.
The number 7 becomes the next digit in our result. 
Result so far: 347562.57
If we subtract 1442 from 1600, we get 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

On to step 11:
The number 206 fits into 1580 7 times, leaving a remainder of 138.
The number 7 becomes the next digit in our result. 
Result so far: 347562.577
Subtracting 1442 from 1580 leaves us with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

The final result is 347562.577 with a remainder of 0.0138.
