71904739 ÷ 623 
We want to figure out the number of times 71904739 can be divided by 623.

Going ahead to step 1:
When dividing 7 by 623, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 623

Advancing to step 2:
71 divided by 623 is 0 with a remainder of 71.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 71, we get 71.
Append the next digit (9) from the dividend to 71 and continue with: 719 / 623

Step 3:
623 goes into 719 1 times with a remainder of 96.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 623 from 719 and we're left with 96.
Fetch the next digit (0) from the dividend, attach it to 96 and continue: 960 / 623

Moving on to step 4:
The number 623 fits into 960 1 times, leaving a remainder of 337.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Subtract 623 from 960 to get 337.
Include the next digit (4) from the dividend after 337, then repeat: 3374 / 623

Advancing to step 5:
623 can be fit into 3374 5 times, resulting in a remainder of 259.
Record the quotient 5 as the next digit in the result. 
Result so far: 115.0
Deduct 3115 from 3374 and we're left with 259.
Bring next digit (7) of the dividend behind the 259 and repeat the process: 2597 / 623

On to step 6:
When dividing 2597 by 623, we get 4 with a remainder of 105.
Put 4 as the next digit of the answer. 
Result so far: 1154.0
Deduct 2492 from 2597 and we're left with 105.
Include the next digit (3) from the dividend after 105, then repeat: 1053 / 623

Advancing to step 7:
If we divide 1053 by 623, we get 1 and a remainder of 430.
Write down 1 as next digit of the result. 
Result so far: 11541.0
Subtracting 623 from 1053 leaves us with 430.
Fetch the next digit (9) from the dividend, attach it to 430 and continue: 4309 / 623

Moving on to step 8:
623 can be fit into 4309 6 times, resulting in a remainder of 571.
Use 6 as the next digit of our solution. 
Result so far: 115416.0
If we take 3738 away from 4309, we end up with 571.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5710, and continue the process.

Let's proceed to step 9:
623 can be fit into 5710 9 times, resulting in a remainder of 103.
Put 9 as the next digit of the answer. 
Result so far: 115416.9
Subtract 5607 from 5710 to get 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Moving on to step 10:
The number 623 fits into 1030 1 times, leaving a remainder of 407.
Record the quotient 1 as the next digit in the result. 
Result so far: 115416.91
Deduct 623 from 1030 and we're left with 407.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4070, and continue the process.

On to step 11:
623 goes into 4070 6 times with a remainder of 332.
Write down 6 as next digit of the result. 
Result so far: 115416.916
Deduct 3738 from 4070 and we're left with 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

Going ahead to step 12:
When dividing 3320 by 623, we get 5 with a remainder of 205.
The number 5 becomes the next digit in our result. 
Result so far: 115416.9165
The remainder is 205 after subtracting 3115 from 3320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

On to step 13:
When dividing 2050 by 623, we get 3 with a remainder of 181.
Use 3 as the next digit of our solution. 
Result so far: 115416.91653
If we take 1869 away from 2050, we end up with 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

Going ahead to step 14:
623 can be fit into 1810 2 times, resulting in a remainder of 564.
Record the quotient 2 as the next digit in the result. 
Result so far: 115416.916532
If we take 1246 away from 1810, we end up with 564.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5640, and continue the process.

On to step 15:
When dividing 5640 by 623, we get 9 with a remainder of 33.
Record the quotient 9 as the next digit in the result. 
Result so far: 115416.9165329
Subtracting 5607 from 5640 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 16:
623 goes into 330 0 times with a remainder of 330.
The number 0 becomes the next digit in our result. 
Result so far: 115416.9165329
Subtract 0 from 330 to get 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

The final result is 115416.9165329 with a remainder of 3.3e-07.
