81715019 ÷ 206 
We want to divide 81715019 by 206.

Moving on to step 1:
If we divide 8 by 206, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 206

Step 2:
If we divide 81 by 206, we get 0 and a remainder of 81.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 81 leaves us with 81.
Bring next digit (7) of the dividend behind the 81 and repeat the process: 817 / 206

Going ahead to step 3:
If we divide 817 by 206, we get 3 and a remainder of 199.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 618 from 817 to get 199.
Include the next digit (1) from the dividend after 199, then repeat: 1991 / 206

Step 4:
1991 divided by 206 is 9 with a remainder of 137.
Put 9 as the next digit of the answer. 
Result so far: 39.0
Subtract 1854 from 1991 to get 137.
Fetch the next digit (5) from the dividend, attach it to 137 and continue: 1375 / 206

Moving on to step 5:
1375 divided by 206 is 6 with a remainder of 139.
Use 6 as the next digit of our solution. 
Result so far: 396.0
If we subtract 1236 from 1375, we get 139.
Bring next digit (0) of the dividend behind the 139 and repeat the process: 1390 / 206

Advancing to step 6:
206 goes into 1390 6 times with a remainder of 154.
Write down 6 as next digit of the result. 
Result so far: 3966.0
Deduct 1236 from 1390 and we're left with 154.
Fetch the next digit (1) from the dividend, attach it to 154 and continue: 1541 / 206

On to step 7:
1541 divided by 206 is 7 with a remainder of 99.
The number 7 becomes the next digit in our result. 
Result so far: 39667.0
If we subtract 1442 from 1541, we get 99.
Take the next digit (9) from the dividend and append it to 99, then repeat: 999 / 206

Moving on to step 8:
When dividing 999 by 206, we get 4 with a remainder of 175.
Record the quotient 4 as the next digit in the result. 
Result so far: 396674.0
Deduct 824 from 999 and we're left with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Moving on to step 9:
If we divide 1750 by 206, we get 8 and a remainder of 102.
Record the quotient 8 as the next digit in the result. 
Result so far: 396674.8
Subtracting 1648 from 1750 leaves us with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Step 10:
206 goes into 1020 4 times with a remainder of 196.
Write down 4 as next digit of the result. 
Result so far: 396674.84
The remainder is 196 after subtracting 824 from 1020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Going ahead to step 11:
When dividing 1960 by 206, we get 9 with a remainder of 106.
Put 9 as the next digit of the answer. 
Result so far: 396674.849
If we take 1854 away from 1960, we end up with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Advancing to step 12:
When dividing 1060 by 206, we get 5 with a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 396674.8495
If we take 1030 away from 1060, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 13:
If we divide 300 by 206, we get 1 and a remainder of 94.
Record the quotient 1 as the next digit in the result. 
Result so far: 396674.84951
If we take 206 away from 300, we end up with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Step 14:
206 goes into 940 4 times with a remainder of 116.
Use 4 as the next digit of our solution. 
Result so far: 396674.849514
If we subtract 824 from 940, we get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Going ahead to step 15:
206 can be fit into 1160 5 times, resulting in a remainder of 130.
The number 5 becomes the next digit in our result. 
Result so far: 396674.8495145
If we take 1030 away from 1160, we end up with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Going ahead to step 16:
The number 206 fits into 1300 6 times, leaving a remainder of 64.
Write down 6 as next digit of the result. 
Result so far: 396674.84951456
Subtracting 1236 from 1300 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

In conclusion, the division gives 396674.84951456 with a balance of 6.4e-08.
