71620169 ÷ 912 
We want to figure out the number of times 71620169 can be divided by 912.

On to step 1:
If we divide 7 by 912, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 912

Let's proceed to step 2:
If we divide 71 by 912, we get 0 and a remainder of 71.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 71 after subtracting 0 from 71.
Take the next digit (6) from the dividend and append it to 71, then repeat: 716 / 912

Step 3:
912 goes into 716 0 times with a remainder of 716.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 716 after subtracting 0 from 716.
Append the next digit (2) from the dividend to 716 and continue with: 7162 / 912

Moving on to step 4:
7162 divided by 912 is 7 with a remainder of 778.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we subtract 6384 from 7162, we get 778.
Fetch the next digit (0) from the dividend, attach it to 778 and continue: 7780 / 912

Let's proceed to step 5:
When dividing 7780 by 912, we get 8 with a remainder of 484.
The next digit of our result is 8. 
Result so far: 78.0
If we subtract 7296 from 7780, we get 484.
Include the next digit (1) from the dividend after 484, then repeat: 4841 / 912

On to step 6:
When dividing 4841 by 912, we get 5 with a remainder of 281.
Record the quotient 5 as the next digit in the result. 
Result so far: 785.0
Deduct 4560 from 4841 and we're left with 281.
Include the next digit (6) from the dividend after 281, then repeat: 2816 / 912

Step 7:
912 goes into 2816 3 times with a remainder of 80.
Put 3 as the next digit of the answer. 
Result so far: 7853.0
If we subtract 2736 from 2816, we get 80.
Take the next digit (9) from the dividend and append it to 80, then repeat: 809 / 912

On to step 8:
The number 912 fits into 809 0 times, leaving a remainder of 809.
Use 0 as the next digit of our solution. 
Result so far: 78530.0
Subtract 0 from 809 to get 809.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8090, and continue the process.

Going ahead to step 9:
8090 divided by 912 is 8 with a remainder of 794.
Write down 8 as next digit of the result. 
Result so far: 78530.8
If we take 7296 away from 8090, we end up with 794.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7940, and continue the process.

Advancing to step 10:
912 can be fit into 7940 8 times, resulting in a remainder of 644.
Put 8 as the next digit of the answer. 
Result so far: 78530.88
Subtract 7296 from 7940 to get 644.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6440, and continue the process.

In conclusion, the division gives 78530.88 with a balance of 0.644.
