51331066 ÷ 163 
Our goal is to divide 51331066 by 163.

Advancing to step 1:
When dividing 5 by 163, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 163

On to step 2:
If we divide 51 by 163, we get 0 and a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 51 and we're left with 51.
Bring next digit (3) of the dividend behind the 51 and repeat the process: 513 / 163

On to step 3:
163 can be fit into 513 3 times, resulting in a remainder of 24.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we take 489 away from 513, we end up with 24.
Fetch the next digit (3) from the dividend, attach it to 24 and continue: 243 / 163

Step 4:
163 goes into 243 1 times with a remainder of 80.
The next digit of our result is 1. 
Result so far: 31.0
Deduct 163 from 243 and we're left with 80.
Grab the next digit (1) from the dividend, add it to 80, then carry on: 801 / 163

Let's proceed to step 5:
If we divide 801 by 163, we get 4 and a remainder of 149.
Write down 4 as next digit of the result. 
Result so far: 314.0
If we subtract 652 from 801, we get 149.
Append the next digit (0) from the dividend to 149 and continue with: 1490 / 163

Let's proceed to step 6:
1490 divided by 163 is 9 with a remainder of 23.
Put 9 as the next digit of the answer. 
Result so far: 3149.0
Subtract 1467 from 1490 to get 23.
Take the next digit (6) from the dividend and append it to 23, then repeat: 236 / 163

On to step 7:
163 can be fit into 236 1 times, resulting in a remainder of 73.
Write down 1 as next digit of the result. 
Result so far: 31491.0
The remainder is 73 after subtracting 163 from 236.
Fetch the next digit (6) from the dividend, attach it to 73 and continue: 736 / 163

Advancing to step 8:
If we divide 736 by 163, we get 4 and a remainder of 84.
Use 4 as the next digit of our solution. 
Result so far: 314914.0
Subtract 652 from 736 to get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Step 9:
163 can be fit into 840 5 times, resulting in a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 314914.5
Subtract 815 from 840 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 10:
The number 163 fits into 250 1 times, leaving a remainder of 87.
Write down 1 as next digit of the result. 
Result so far: 314914.51
The remainder is 87 after subtracting 163 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Let's proceed to step 11:
163 can be fit into 870 5 times, resulting in a remainder of 55.
The number 5 becomes the next digit in our result. 
Result so far: 314914.515
Deduct 815 from 870 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

On to step 12:
550 divided by 163 is 3 with a remainder of 61.
Put 3 as the next digit of the answer. 
Result so far: 314914.5153
If we take 489 away from 550, we end up with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Let's proceed to step 13:
163 goes into 610 3 times with a remainder of 121.
Use 3 as the next digit of our solution. 
Result so far: 314914.51533
If we subtract 489 from 610, we get 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

After the division, we end up with 314914.51533 and a remainder of 0.000121.
