42163856 ÷ 163 
We want to figure out the number of times 42163856 can be divided by 163.

Going ahead to step 1:
The number 163 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 163

Moving on to step 2:
163 can be fit into 42 0 times, resulting in a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Append the next digit (1) from the dividend to 42 and continue with: 421 / 163

Advancing to step 3:
421 divided by 163 is 2 with a remainder of 95.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 95 after subtracting 326 from 421.
Include the next digit (6) from the dividend after 95, then repeat: 956 / 163

Moving on to step 4:
When dividing 956 by 163, we get 5 with a remainder of 141.
Use 5 as the next digit of our solution. 
Result so far: 25.0
If we subtract 815 from 956, we get 141.
Take the next digit (3) from the dividend and append it to 141, then repeat: 1413 / 163

Going ahead to step 5:
If we divide 1413 by 163, we get 8 and a remainder of 109.
The next digit of our result is 8. 
Result so far: 258.0
If we take 1304 away from 1413, we end up with 109.
Grab the next digit (8) from the dividend, add it to 109, then carry on: 1098 / 163

On to step 6:
The number 163 fits into 1098 6 times, leaving a remainder of 120.
The number 6 becomes the next digit in our result. 
Result so far: 2586.0
If we subtract 978 from 1098, we get 120.
Bring next digit (5) of the dividend behind the 120 and repeat the process: 1205 / 163

Step 7:
The number 163 fits into 1205 7 times, leaving a remainder of 64.
The next digit of our result is 7. 
Result so far: 25867.0
The remainder is 64 after subtracting 1141 from 1205.
Include the next digit (6) from the dividend after 64, then repeat: 646 / 163

Step 8:
646 divided by 163 is 3 with a remainder of 157.
The number 3 becomes the next digit in our result. 
Result so far: 258673.0
Deduct 489 from 646 and we're left with 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

On to step 9:
When dividing 1570 by 163, we get 9 with a remainder of 103.
Put 9 as the next digit of the answer. 
Result so far: 258673.9
Deduct 1467 from 1570 and we're left with 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Going ahead to step 10:
163 goes into 1030 6 times with a remainder of 52.
Use 6 as the next digit of our solution. 
Result so far: 258673.96
Subtracting 978 from 1030 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 11:
520 divided by 163 is 3 with a remainder of 31.
The number 3 becomes the next digit in our result. 
Result so far: 258673.963
Subtracting 489 from 520 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 12:
The number 163 fits into 310 1 times, leaving a remainder of 147.
Record the quotient 1 as the next digit in the result. 
Result so far: 258673.9631
The remainder is 147 after subtracting 163 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

Advancing to step 13:
163 goes into 1470 9 times with a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 258673.96319
Deduct 1467 from 1470 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 14:
If we divide 30 by 163, we get 0 and a remainder of 30.
The next digit of our result is 0. 
Result so far: 258673.96319
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 15:
The number 163 fits into 300 1 times, leaving a remainder of 137.
The number 1 becomes the next digit in our result. 
Result so far: 258673.9631901
If we subtract 163 from 300, we get 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

On to step 16:
163 can be fit into 1370 8 times, resulting in a remainder of 66.
Use 8 as the next digit of our solution. 
Result so far: 258673.96319018
The remainder is 66 after subtracting 1304 from 1370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

The final result is 258673.96319018 with a remainder of 6.6e-08.
