81703000 ÷ 402 
Let's see how many times 402 fits into 81703000.

Let's proceed to step 1:
8 divided by 402 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 402

Moving on to step 2:
81 divided by 402 is 0 with a remainder of 81.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Fetch the next digit (7) from the dividend, attach it to 81 and continue: 817 / 402

On to step 3:
When dividing 817 by 402, we get 2 with a remainder of 13.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 804 from 817 and we're left with 13.
Take the next digit (0) from the dividend and append it to 13, then repeat: 130 / 402

On to step 4:
When dividing 130 by 402, we get 0 with a remainder of 130.
The next digit of our result is 0. 
Result so far: 20.0
Deduct 0 from 130 and we're left with 130.
Fetch the next digit (3) from the dividend, attach it to 130 and continue: 1303 / 402

On to step 5:
402 can be fit into 1303 3 times, resulting in a remainder of 97.
Write down 3 as next digit of the result. 
Result so far: 203.0
Subtract 1206 from 1303 to get 97.
Grab the next digit (0) from the dividend, add it to 97, then carry on: 970 / 402

Step 6:
If we divide 970 by 402, we get 2 and a remainder of 166.
Record the quotient 2 as the next digit in the result. 
Result so far: 2032.0
If we take 804 away from 970, we end up with 166.
Bring next digit (0) of the dividend behind the 166 and repeat the process: 1660 / 402

On to step 7:
402 goes into 1660 4 times with a remainder of 52.
The next digit of our result is 4. 
Result so far: 20324.0
If we take 1608 away from 1660, we end up with 52.
Grab the next digit (0) from the dividend, add it to 52, then carry on: 520 / 402

Moving on to step 8:
520 divided by 402 is 1 with a remainder of 118.
The next digit of our result is 1. 
Result so far: 203241.0
If we subtract 402 from 520, we get 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Moving on to step 9:
402 goes into 1180 2 times with a remainder of 376.
Record the quotient 2 as the next digit in the result. 
Result so far: 203241.2
Deduct 804 from 1180 and we're left with 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Advancing to step 10:
402 goes into 3760 9 times with a remainder of 142.
Write down 9 as next digit of the result. 
Result so far: 203241.29
Subtract 3618 from 3760 to get 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Moving on to step 11:
402 goes into 1420 3 times with a remainder of 214.
Record the quotient 3 as the next digit in the result. 
Result so far: 203241.293
If we take 1206 away from 1420, we end up with 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

On to step 12:
402 can be fit into 2140 5 times, resulting in a remainder of 130.
Use 5 as the next digit of our solution. 
Result so far: 203241.2935
Subtracting 2010 from 2140 leaves us 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.

Let's proceed to step 13:
402 can be fit into 1300 3 times, resulting in a remainder of 94.
The number 3 becomes the next digit in our result. 
Result so far: 203241.29353
If we subtract 1206 from 1300, we get 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Moving on to step 14:
When dividing 940 by 402, we get 2 with a remainder of 136.
The number 2 becomes the next digit in our result. 
Result so far: 203241.293532
The remainder is 136 after subtracting 804 from 940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Moving on to step 15:
The number 402 fits into 1360 3 times, leaving a remainder of 154.
Put 3 as the next digit of the answer. 
Result so far: 203241.2935323
Subtracting 1206 from 1360 leaves us with 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Let's proceed to step 16:
If we divide 1540 by 402, we get 3 and a remainder of 334.
Write down 3 as next digit of the result. 
Result so far: 203241.29353233
Subtracting 1206 from 1540 leaves us with 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

The final result is 203241.29353233 with a remainder of 3.34e-07.
