Let's divide 51438917 by 831
We want to divide 51438917 by 831.

On to step 1:
The number 831 fits into 5 0 times, leaving a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 831

Advancing to step 2:
The number 831 fits into 51 0 times, leaving a remainder of 51.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 51 after subtracting 0 from 51.
Bring next digit (4) of the dividend behind the 51 and repeat the process: 514 / 831

On to step 3:
The number 831 fits into 514 0 times, leaving a remainder of 514.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 514 after subtracting 0 from 514.
Append the next digit (3) from the dividend to 514 and continue with: 5143 / 831

On to step 4:
831 goes into 5143 6 times with a remainder of 157.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtracting 4986 from 5143 leaves us with 157.
Bring next digit (8) of the dividend behind the 157 and repeat the process: 1578 / 831

Moving on to step 5:
1578 divided by 831 is 1 with a remainder of 747.
The next digit of our result is 1. 
Result so far: 61.0
If we take 831 away from 1578, we end up with 747.
Append the next digit (9) from the dividend to 747 and continue with: 7479 / 831

Going ahead to step 6:
When dividing 7479 by 831, we get 9 with a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 619.0
The remainder is 0 after subtracting 7479 from 7479.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 831

Moving on to step 7:
831 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 6190.0
If we subtract 0 from 1, we get 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 831

Step 8:
17 divided by 831 is 0 with a remainder of 17.
Use 0 as the next digit of our solution. 
Result so far: 61900.0
Deduct 0 from 17 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 9:
170 divided by 831 is 0 with a remainder of 170.
Record the quotient 0 as the next digit in the result. 
Result so far: 61900.0
The remainder is 170 after subtracting 0 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

On to step 10:
When dividing 1700 by 831, we get 2 with a remainder of 38.
The next digit of our result is 2. 
Result so far: 61900.02
If we take 1662 away from 1700, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 11:
If we divide 380 by 831, we get 0 and a remainder of 380.
Write down 0 as next digit of the result. 
Result so far: 61900.02
Subtract 0 from 380 to get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Advancing to step 12:
The number 831 fits into 3800 4 times, leaving a remainder of 476.
Write down 4 as next digit of the result. 
Result so far: 61900.0204
Subtracting 3324 from 3800 leaves us with 476.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

Advancing to step 13:
831 goes into 4760 5 times with a remainder of 605.
Write down 5 as next digit of the result. 
Result so far: 61900.02045
Subtracting 4155 from 4760 leaves us with 605.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6050, and continue the process.

Let's proceed to step 14:
831 can be fit into 6050 7 times, resulting in a remainder of 233.
Write down 7 as next digit of the result. 
Result so far: 61900.020457
If we subtract 5817 from 6050, we get 233.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

On to step 15:
If we divide 2330 by 831, we get 2 and a remainder of 668.
Record the quotient 2 as the next digit in the result. 
Result so far: 61900.0204572
Subtracting 1662 from 2330 leaves us with 668.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6680, and continue the process.

Let's proceed to step 16:
6680 divided by 831 is 8 with a remainder of 32.
Put 8 as the next digit of the answer. 
Result so far: 61900.02045728
Subtracting 6648 from 6680 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

In conclusion, the division gives 61900.02045728 with a balance of 3.2e-08.
