68140955 ÷ 170 
Our goal is to divide 68140955 by 170.

Moving on to step 1:
6 divided by 170 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 170

Let's proceed to step 2:
170 can be fit into 68 0 times, resulting in a remainder of 68.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 68 leaves us with 68.
Fetch the next digit (1) from the dividend, attach it to 68 and continue: 681 / 170

Going ahead to step 3:
If we divide 681 by 170, we get 4 and a remainder of 1.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Deduct 680 from 681 and we're left with 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 170

Let's proceed to step 4:
14 divided by 170 is 0 with a remainder of 14.
The number 0 becomes the next digit in our result. 
Result so far: 40.0
Deduct 0 from 14 and we're left with 14.
Take the next digit (0) from the dividend and append it to 14, then repeat: 140 / 170

Let's proceed to step 5:
If we divide 140 by 170, we get 0 and a remainder of 140.
Record the quotient 0 as the next digit in the result. 
Result so far: 400.0
Subtract 0 from 140 to get 140.
Fetch the next digit (9) from the dividend, attach it to 140 and continue: 1409 / 170

On to step 6:
170 can be fit into 1409 8 times, resulting in a remainder of 49.
Record the quotient 8 as the next digit in the result. 
Result so far: 4008.0
If we subtract 1360 from 1409, we get 49.
Fetch the next digit (5) from the dividend, attach it to 49 and continue: 495 / 170

Advancing to step 7:
495 divided by 170 is 2 with a remainder of 155.
The number 2 becomes the next digit in our result. 
Result so far: 40082.0
If we take 340 away from 495, we end up with 155.
Fetch the next digit (5) from the dividend, attach it to 155 and continue: 1555 / 170

Going ahead to step 8:
170 can be fit into 1555 9 times, resulting in a remainder of 25.
Record the quotient 9 as the next digit in the result. 
Result so far: 400829.0
Deduct 1530 from 1555 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 9:
If we divide 250 by 170, we get 1 and a remainder of 80.
The number 1 becomes the next digit in our result. 
Result so far: 400829.1
Subtracting 170 from 250 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 10:
170 goes into 800 4 times with a remainder of 120.
The number 4 becomes the next digit in our result. 
Result so far: 400829.14
If we subtract 680 from 800, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Advancing to step 11:
If we divide 1200 by 170, we get 7 and a remainder of 10.
The next digit of our result is 7. 
Result so far: 400829.147
If we subtract 1190 from 1200, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 12:
The number 170 fits into 100 0 times, leaving a remainder of 100.
Use 0 as the next digit of our solution. 
Result so far: 400829.147
The remainder is 100 after subtracting 0 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Moving on to step 13:
If we divide 1000 by 170, we get 5 and a remainder of 150.
Record the quotient 5 as the next digit in the result. 
Result so far: 400829.14705
Subtract 850 from 1000 to get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Let's proceed to step 14:
The number 170 fits into 1500 8 times, leaving a remainder of 140.
The number 8 becomes the next digit in our result. 
Result so far: 400829.147058
Deduct 1360 from 1500 and we're left with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Going ahead to step 15:
The number 170 fits into 1400 8 times, leaving a remainder of 40.
Record the quotient 8 as the next digit in the result. 
Result so far: 400829.1470588
If we subtract 1360 from 1400, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

In conclusion, the division gives 400829.1470588 with a balance of 4e-07.
