We look at the division of 51123443 by 392 
We're looking to find how many times 392 goes into 51123443.

Going ahead to step 1:
When dividing 5 by 392, we get 0 with 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.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 392

Advancing to step 2:
When dividing 51 by 392, we get 0 with a remainder of 51.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 51, we get 51.
Bring next digit (1) of the dividend behind the 51 and repeat the process: 511 / 392

Let's proceed to step 3:
The number 392 fits into 511 1 times, leaving a remainder of 119.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 392 from 511 to get 119.
Include the next digit (2) from the dividend after 119, then repeat: 1192 / 392

On to step 4:
1192 divided by 392 is 3 with a remainder of 16.
The next digit of our result is 3. 
Result so far: 13.0
The remainder is 16 after subtracting 1176 from 1192.
Append the next digit (3) from the dividend to 16 and continue with: 163 / 392

Advancing to step 5:
When dividing 163 by 392, we get 0 with a remainder of 163.
Record the quotient 0 as the next digit in the result. 
Result so far: 130.0
Subtracting 0 from 163 leaves us with 163.
Include the next digit (4) from the dividend after 163, then repeat: 1634 / 392

Step 6:
1634 divided by 392 is 4 with a remainder of 66.
Record the quotient 4 as the next digit in the result. 
Result so far: 1304.0
Subtract 1568 from 1634 to get 66.
Include the next digit (4) from the dividend after 66, then repeat: 664 / 392

On to step 7:
When dividing 664 by 392, we get 1 with a remainder of 272.
Use 1 as the next digit of our solution. 
Result so far: 13041.0
If we take 392 away from 664, we end up with 272.
Grab the next digit (3) from the dividend, add it to 272, then carry on: 2723 / 392

Let's proceed to step 8:
The number 392 fits into 2723 6 times, leaving a remainder of 371.
Record the quotient 6 as the next digit in the result. 
Result so far: 130416.0
Subtract 2352 from 2723 to get 371.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3710, and continue the process.

Let's proceed to step 9:
If we divide 3710 by 392, we get 9 and a remainder of 182.
Record the quotient 9 as the next digit in the result. 
Result so far: 130416.9
If we subtract 3528 from 3710, we get 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Let's proceed to step 10:
1820 divided by 392 is 4 with a remainder of 252.
Record the quotient 4 as the next digit in the result. 
Result so far: 130416.94
Subtract 1568 from 1820 to get 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Moving on to step 11:
2520 divided by 392 is 6 with a remainder of 168.
The number 6 becomes the next digit in our result. 
Result so far: 130416.946
Subtracting 2352 from 2520 leaves us with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Advancing to step 12:
1680 divided by 392 is 4 with a remainder of 112.
Put 4 as the next digit of the answer. 
Result so far: 130416.9464
If we take 1568 away from 1680, we end up with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Moving on to step 13:
392 goes into 1120 2 times with a remainder of 336.
Use 2 as the next digit of our solution. 
Result so far: 130416.94642
Subtract 784 from 1120 to get 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

On to step 14:
When dividing 3360 by 392, we get 8 with a remainder of 224.
Record the quotient 8 as the next digit in the result. 
Result so far: 130416.946428
Subtracting 3136 from 3360 leaves us with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Step 15:
When dividing 2240 by 392, we get 5 with a remainder of 280.
The next digit of our result is 5. 
Result so far: 130416.9464285
Subtract 1960 from 2240 to get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Going ahead to step 16:
392 goes into 2800 7 times with a remainder of 56.
Write down 7 as next digit of the result. 
Result so far: 130416.94642857
If we subtract 2744 from 2800, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

The final outcome is 130416.94642857, with a leftover of 5.6e-08.
