Let's divide 31210729 by 619
Our goal is to divide 31210729 by 619.

Moving on to step 1:
If we divide 3 by 619, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 619

Step 2:
If we divide 31 by 619, we get 0 and a remainder of 31.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 31 and we're left with 31.
Grab the next digit (2) from the dividend, add it to 31, then carry on: 312 / 619

Let's proceed to step 3:
312 divided by 619 is 0 with a remainder of 312.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 312, we end up with 312.
Append the next digit (1) from the dividend to 312 and continue with: 3121 / 619

Step 4:
619 goes into 3121 5 times with a remainder of 26.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtract 3095 from 3121 to get 26.
Take the next digit (0) from the dividend and append it to 26, then repeat: 260 / 619

Let's proceed to step 5:
260 divided by 619 is 0 with a remainder of 260.
The next digit of our result is 0. 
Result so far: 50.0
If we take 0 away from 260, we end up with 260.
Include the next digit (7) from the dividend after 260, then repeat: 2607 / 619

Going ahead to step 6:
The number 619 fits into 2607 4 times, leaving a remainder of 131.
Put 4 as the next digit of the answer. 
Result so far: 504.0
Subtracting 2476 from 2607 leaves us with 131.
Take the next digit (2) from the dividend and append it to 131, then repeat: 1312 / 619

Moving on to step 7:
When dividing 1312 by 619, we get 2 with a remainder of 74.
The next digit of our result is 2. 
Result so far: 5042.0
If we subtract 1238 from 1312, we get 74.
Bring next digit (9) of the dividend behind the 74 and repeat the process: 749 / 619

Going ahead to step 8:
When dividing 749 by 619, we get 1 with a remainder of 130.
Write down 1 as next digit of the result. 
Result so far: 50421.0
The remainder is 130 after subtracting 619 from 749.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

On to step 9:
619 can be fit into 1300 2 times, resulting in a remainder of 62.
The next digit of our result is 2. 
Result so far: 50421.2
Deduct 1238 from 1300 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 10:
If we divide 620 by 619, we get 1 and a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 50421.21
The remainder is 1 after subtracting 619 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 11:
If we divide 10 by 619, we get 0 and a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 50421.21
If we take 0 away from 10, we end up 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.

Let's proceed to step 12:
619 can be fit into 100 0 times, resulting in a remainder of 100.
Put 0 as the next digit of the answer. 
Result so far: 50421.21
If we take 0 away from 100, we end up 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.

Our division results in 50421.21 with a remaining 0.001.
