We look at the division of 54580774 by 690 
We want to figure out the number of times 54580774 can be divided by 690.

On to step 1:
690 can be fit into 5 0 times, resulting in a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 690

Going ahead to step 2:
The number 690 fits into 54 0 times, leaving a remainder of 54.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 54 and we're left with 54.
Include the next digit (5) from the dividend after 54, then repeat: 545 / 690

Moving on to step 3:
When dividing 545 by 690, we get 0 with a remainder of 545.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 545 to get 545.
Include the next digit (8) from the dividend after 545, then repeat: 5458 / 690

Moving on to step 4:
5458 divided by 690 is 7 with a remainder of 628.
The next digit of our result is 7. 
Result so far: 7.0
Subtracting 4830 from 5458 leaves us with 628.
Include the next digit (0) from the dividend after 628, then repeat: 6280 / 690

Let's proceed to step 5:
When dividing 6280 by 690, we get 9 with a remainder of 70.
The next digit of our result is 9. 
Result so far: 79.0
Deduct 6210 from 6280 and we're left with 70.
Take the next digit (7) from the dividend and append it to 70, then repeat: 707 / 690

On to step 6:
If we divide 707 by 690, we get 1 and a remainder of 17.
The next digit of our result is 1. 
Result so far: 791.0
Subtracting 690 from 707 leaves us with 17.
Take the next digit (7) from the dividend and append it to 17, then repeat: 177 / 690

On to step 7:
If we divide 177 by 690, we get 0 and a remainder of 177.
The next digit of our result is 0. 
Result so far: 7910.0
Subtracting 0 from 177 leaves us with 177.
Fetch the next digit (4) from the dividend, attach it to 177 and continue: 1774 / 690

Going ahead to step 8:
The number 690 fits into 1774 2 times, leaving a remainder of 394.
Record the quotient 2 as the next digit in the result. 
Result so far: 79102.0
Subtracting 1380 from 1774 leaves us with 394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

Step 9:
690 can be fit into 3940 5 times, resulting in a remainder of 490.
Put 5 as the next digit of the answer. 
Result so far: 79102.5
Subtracting 3450 from 3940 leaves us with 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Step 10:
690 can be fit into 4900 7 times, resulting in a remainder of 70.
Use 7 as the next digit of our solution. 
Result so far: 79102.57
The remainder is 70 after subtracting 4830 from 4900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 11:
When dividing 700 by 690, we get 1 with a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 79102.571
Subtract 690 from 700 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 12:
The number 690 fits into 100 0 times, leaving a remainder of 100.
Use 0 as the next digit of our solution. 
Result so far: 79102.571
Deduct 0 from 100 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 13:
690 can be fit into 1000 1 times, resulting in a remainder of 310.
The number 1 becomes the next digit in our result. 
Result so far: 79102.57101
If we subtract 690 from 1000, we get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Advancing to step 14:
The number 690 fits into 3100 4 times, leaving a remainder of 340.
The number 4 becomes the next digit in our result. 
Result so far: 79102.571014
If we subtract 2760 from 3100, we get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Going ahead to step 15:
The number 690 fits into 3400 4 times, leaving a remainder of 640.
Write down 4 as next digit of the result. 
Result so far: 79102.5710144
Deduct 2760 from 3400 and we're left with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

The final result is 79102.5710144 with a remainder of 6.4e-06.
