We look at the division of 51672318 by 170 
We want to divide 51672318 by 170.

Step 1:
When dividing 5 by 170, 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.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 170

Step 2:
When dividing 51 by 170, we get 0 with a remainder of 51.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 51, we get 51.
Fetch the next digit (6) from the dividend, attach it to 51 and continue: 516 / 170

Moving on to step 3:
If we divide 516 by 170, we get 3 and a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 510 away from 516, we end up with 6.
Take the next digit (7) from the dividend and append it to 6, then repeat: 67 / 170

Advancing to step 4:
When dividing 67 by 170, we get 0 with a remainder of 67.
Use 0 as the next digit of our solution. 
Result so far: 30.0
Deduct 0 from 67 and we're left with 67.
Append the next digit (2) from the dividend to 67 and continue with: 672 / 170

Moving on to step 5:
If we divide 672 by 170, we get 3 and a remainder of 162.
Put 3 as the next digit of the answer. 
Result so far: 303.0
Subtracting 510 from 672 leaves us with 162.
Append the next digit (3) from the dividend to 162 and continue with: 1623 / 170

Step 6:
If we divide 1623 by 170, we get 9 and a remainder of 93.
The next digit of our result is 9. 
Result so far: 3039.0
If we subtract 1530 from 1623, we get 93.
Bring next digit (1) of the dividend behind the 93 and repeat the process: 931 / 170

Advancing to step 7:
If we divide 931 by 170, we get 5 and a remainder of 81.
Put 5 as the next digit of the answer. 
Result so far: 30395.0
If we subtract 850 from 931, we get 81.
Bring next digit (8) of the dividend behind the 81 and repeat the process: 818 / 170

On to step 8:
170 can be fit into 818 4 times, resulting in a remainder of 138.
Use 4 as the next digit of our solution. 
Result so far: 303954.0
Subtract 680 from 818 to get 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

On to step 9:
1380 divided by 170 is 8 with a remainder of 20.
Put 8 as the next digit of the answer. 
Result so far: 303954.8
Deduct 1360 from 1380 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.

Step 10:
When dividing 200 by 170, we get 1 with a remainder of 30.
The next digit of our result is 1. 
Result so far: 303954.81
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.

Let's proceed to step 11:
170 goes into 300 1 times with a remainder of 130.
The number 1 becomes the next digit in our result. 
Result so far: 303954.811
Deduct 170 from 300 and we're left 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 303954.811 with a remainder of 0.013.
