We're dividing 65391400 by 170 
We want to divide 65391400 by 170.

Step 1:
170 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (5) of the dividend behind the 6 and repeat the process: 65 / 170

Step 2:
The number 170 fits into 65 0 times, leaving a remainder of 65.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 65 to get 65.
Fetch the next digit (3) from the dividend, attach it to 65 and continue: 653 / 170

On to step 3:
170 goes into 653 3 times with a remainder of 143.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 510 from 653 leaves us with 143.
Append the next digit (9) from the dividend to 143 and continue with: 1439 / 170

Step 4:
1439 divided by 170 is 8 with a remainder of 79.
Put 8 as the next digit of the answer. 
Result so far: 38.0
Subtracting 1360 from 1439 leaves us with 79.
Include the next digit (1) from the dividend after 79, then repeat: 791 / 170

Going ahead to step 5:
170 can be fit into 791 4 times, resulting in a remainder of 111.
Write down 4 as next digit of the result. 
Result so far: 384.0
Subtract 680 from 791 to get 111.
Append the next digit (4) from the dividend to 111 and continue with: 1114 / 170

Let's proceed to step 6:
The number 170 fits into 1114 6 times, leaving a remainder of 94.
Put 6 as the next digit of the answer. 
Result so far: 3846.0
Subtract 1020 from 1114 to get 94.
Take the next digit (0) from the dividend and append it to 94, then repeat: 940 / 170

Advancing to step 7:
170 goes into 940 5 times with a remainder of 90.
The number 5 becomes the next digit in our result. 
Result so far: 38465.0
Deduct 850 from 940 and we're left with 90.
Include the next digit (0) from the dividend after 90, then repeat: 900 / 170

Going ahead to step 8:
If we divide 900 by 170, we get 5 and a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 384655.0
If we take 850 away from 900, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 9:
170 can be fit into 500 2 times, resulting in a remainder of 160.
Put 2 as the next digit of the answer. 
Result so far: 384655.2
Subtracting 340 from 500 leaves us 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.

Let's proceed to step 10:
1600 divided by 170 is 9 with a remainder of 70.
Write down 9 as next digit of the result. 
Result so far: 384655.29
Subtract 1530 from 1600 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 11:
If we divide 700 by 170, we get 4 and a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 384655.294
Deduct 680 from 700 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 12:
170 can be fit into 200 1 times, resulting in a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 384655.2941
Subtracting 170 from 200 leaves us 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.

Step 13:
If we divide 300 by 170, we get 1 and a remainder of 130.
Record the quotient 1 as the next digit in the result. 
Result so far: 384655.29411
If we take 170 away from 300, 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.

The final result is 384655.29411 with a remainder of 0.00013.
