40685455 ÷ 170 
We want to divide 40685455 by 170.

Let's proceed to step 1:
When dividing 4 by 170, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 170

Step 2:
When dividing 40 by 170, we get 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 40 leaves us with 40.
Fetch the next digit (6) from the dividend, attach it to 40 and continue: 406 / 170

Going ahead to step 3:
170 can be fit into 406 2 times, resulting in a remainder of 66.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 340 from 406 to get 66.
Bring next digit (8) of the dividend behind the 66 and repeat the process: 668 / 170

On to step 4:
668 divided by 170 is 3 with a remainder of 158.
The next digit of our result is 3. 
Result so far: 23.0
Deduct 510 from 668 and we're left with 158.
Append the next digit (5) from the dividend to 158 and continue with: 1585 / 170

Advancing to step 5:
The number 170 fits into 1585 9 times, leaving a remainder of 55.
Put 9 as the next digit of the answer. 
Result so far: 239.0
If we subtract 1530 from 1585, we get 55.
Take the next digit (4) from the dividend and append it to 55, then repeat: 554 / 170

Moving on to step 6:
170 can be fit into 554 3 times, resulting in a remainder of 44.
The next digit of our result is 3. 
Result so far: 2393.0
Subtract 510 from 554 to get 44.
Grab the next digit (5) from the dividend, add it to 44, then carry on: 445 / 170

On to step 7:
The number 170 fits into 445 2 times, leaving a remainder of 105.
Use 2 as the next digit of our solution. 
Result so far: 23932.0
If we take 340 away from 445, we end up with 105.
Fetch the next digit (5) from the dividend, attach it to 105 and continue: 1055 / 170

Step 8:
1055 divided by 170 is 6 with a remainder of 35.
The number 6 becomes the next digit in our result. 
Result so far: 239326.0
If we take 1020 away from 1055, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 9:
When dividing 350 by 170, we get 2 with a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 239326.2
Subtracting 340 from 350 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 10:
The number 170 fits into 100 0 times, leaving a remainder of 100.
Record the quotient 0 as the next digit in the result. 
Result so far: 239326.2
Deduct 0 from 100 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 11:
170 goes into 1000 5 times with a remainder of 150.
Put 5 as the next digit of the answer. 
Result so far: 239326.205
If we take 850 away from 1000, we end up with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Moving on to step 12:
1500 divided by 170 is 8 with a remainder of 140.
Write down 8 as next digit of the result. 
Result so far: 239326.2058
Subtracting 1360 from 1500 leaves us 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.

On to step 13:
When dividing 1400 by 170, we get 8 with a remainder of 40.
Record the quotient 8 as the next digit in the result. 
Result so far: 239326.20588
Subtract 1360 from 1400 to 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 239326.20588 with a balance of 4e-05.
