We're dividing 39788123 by 73 
We want to figure out the number of times 39788123 can be divided by 73.

On to step 1:
73 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 73

On to step 2:
73 can be fit into 39 0 times, resulting in a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Bring next digit (7) of the dividend behind the 39 and repeat the process: 397 / 73

On to step 3:
If we divide 397 by 73, we get 5 and a remainder of 32.
The next digit of our result is 5. 
Result so far: 5.0
Subtract 365 from 397 to get 32.
Grab the next digit (8) from the dividend, add it to 32, then carry on: 328 / 73

Moving on to step 4:
73 can be fit into 328 4 times, resulting in a remainder of 36.
The number 4 becomes the next digit in our result. 
Result so far: 54.0
Deduct 292 from 328 and we're left with 36.
Bring next digit (8) of the dividend behind the 36 and repeat the process: 368 / 73

On to step 5:
If we divide 368 by 73, we get 5 and a remainder of 3.
Use 5 as the next digit of our solution. 
Result so far: 545.0
The remainder is 3 after subtracting 365 from 368.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 73

On to step 6:
If we divide 31 by 73, we get 0 and a remainder of 31.
The next digit of our result is 0. 
Result so far: 5450.0
Deduct 0 from 31 and we're left with 31.
Fetch the next digit (2) from the dividend, attach it to 31 and continue: 312 / 73

Moving on to step 7:
312 divided by 73 is 4 with a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 54504.0
Subtract 292 from 312 to get 20.
Take the next digit (3) from the dividend and append it to 20, then repeat: 203 / 73

On to step 8:
The number 73 fits into 203 2 times, leaving a remainder of 57.
Put 2 as the next digit of the answer. 
Result so far: 545042.0
The remainder is 57 after subtracting 146 from 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Step 9:
If we divide 570 by 73, we get 7 and a remainder of 59.
Record the quotient 7 as the next digit in the result. 
Result so far: 545042.7
If we take 511 away from 570, we end up with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Going ahead to step 10:
When dividing 590 by 73, we get 8 with a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 545042.78
Deduct 584 from 590 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 11:
The number 73 fits into 60 0 times, leaving a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 545042.78
Subtracting 0 from 60 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 12:
When dividing 600 by 73, we get 8 with a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 545042.7808
The remainder is 16 after subtracting 584 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 13:
160 divided by 73 is 2 with a remainder of 14.
Put 2 as the next digit of the answer. 
Result so far: 545042.78082
Subtract 146 from 160 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 14:
The number 73 fits into 140 1 times, leaving a remainder of 67.
The next digit of our result is 1. 
Result so far: 545042.780821
If we take 73 away from 140, we end up with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Advancing to step 15:
73 goes into 670 9 times with a remainder of 13.
Record the quotient 9 as the next digit in the result. 
Result so far: 545042.7808219
Deduct 657 from 670 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 16:
73 goes into 130 1 times with a remainder of 57.
Write down 1 as next digit of the result. 
Result so far: 545042.78082191
The remainder is 57 after subtracting 73 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

After the division, we end up with 545042.78082191 and a remainder of 5.7e-08.
