We're dividing 51331050 by 315 
We want to divide 51331050 by 315.

Let's proceed to step 1:
315 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 315

Moving on to step 2:
If we divide 51 by 315, we get 0 and a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 51 leaves us with 51.
Append the next digit (3) from the dividend to 51 and continue with: 513 / 315

Going ahead to step 3:
When dividing 513 by 315, we get 1 with a remainder of 198.
The next digit of our result is 1. 
Result so far: 1.0
If we take 315 away from 513, we end up with 198.
Include the next digit (3) from the dividend after 198, then repeat: 1983 / 315

Advancing to step 4:
The number 315 fits into 1983 6 times, leaving a remainder of 93.
The next digit of our result is 6. 
Result so far: 16.0
If we take 1890 away from 1983, we end up with 93.
Fetch the next digit (1) from the dividend, attach it to 93 and continue: 931 / 315

On to step 5:
315 goes into 931 2 times with a remainder of 301.
Write down 2 as next digit of the result. 
Result so far: 162.0
The remainder is 301 after subtracting 630 from 931.
Include the next digit (0) from the dividend after 301, then repeat: 3010 / 315

On to step 6:
315 goes into 3010 9 times with a remainder of 175.
Write down 9 as next digit of the result. 
Result so far: 1629.0
If we take 2835 away from 3010, we end up with 175.
Include the next digit (5) from the dividend after 175, then repeat: 1755 / 315

On to step 7:
1755 divided by 315 is 5 with a remainder of 180.
The next digit of our result is 5. 
Result so far: 16295.0
Subtracting 1575 from 1755 leaves us with 180.
Fetch the next digit (0) from the dividend, attach it to 180 and continue: 1800 / 315

Moving on to step 8:
315 goes into 1800 5 times with a remainder of 225.
Record the quotient 5 as the next digit in the result. 
Result so far: 162955.0
Subtracting 1575 from 1800 leaves us with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Going ahead to step 9:
315 goes into 2250 7 times with a remainder of 45.
Use 7 as the next digit of our solution. 
Result so far: 162955.7
The remainder is 45 after subtracting 2205 from 2250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 10:
315 can be fit into 450 1 times, resulting in a remainder of 135.
Put 1 as the next digit of the answer. 
Result so far: 162955.71
If we take 315 away from 450, we end up with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Step 11:
1350 divided by 315 is 4 with a remainder of 90.
Record the quotient 4 as the next digit in the result. 
Result so far: 162955.714
If we take 1260 away from 1350, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Going ahead to step 12:
The number 315 fits into 900 2 times, leaving a remainder of 270.
Use 2 as the next digit of our solution. 
Result so far: 162955.7142
Subtracting 630 from 900 leaves us with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Advancing to step 13:
2700 divided by 315 is 8 with a remainder of 180.
Record the quotient 8 as the next digit in the result. 
Result so far: 162955.71428
Deduct 2520 from 2700 and we're left with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Advancing to step 14:
When dividing 1800 by 315, we get 5 with a remainder of 225.
The next digit of our result is 5. 
Result so far: 162955.714285
Deduct 1575 from 1800 and we're left with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Step 15:
When dividing 2250 by 315, we get 7 with a remainder of 45.
The number 7 becomes the next digit in our result. 
Result so far: 162955.7142857
If we take 2205 away from 2250, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 16:
315 goes into 450 1 times with a remainder of 135.
Record the quotient 1 as the next digit in the result. 
Result so far: 162955.71428571
If we take 315 away from 450, we end up with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

The final outcome is 162955.71428571, with a leftover of 1.35e-07.
