We look at the division of 45420584 by 685 
We want to figure out the number of times 45420584 can be divided by 685.

On to step 1:
685 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 685

Moving on to step 2:
If we divide 45 by 685, we get 0 and a remainder of 45.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 45 after subtracting 0 from 45.
Fetch the next digit (4) from the dividend, attach it to 45 and continue: 454 / 685

Going ahead to step 3:
If we divide 454 by 685, we get 0 and a remainder of 454.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 454, we end up with 454.
Include the next digit (2) from the dividend after 454, then repeat: 4542 / 685

On to step 4:
4542 divided by 685 is 6 with a remainder of 432.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we subtract 4110 from 4542, we get 432.
Include the next digit (0) from the dividend after 432, then repeat: 4320 / 685

Advancing to step 5:
685 goes into 4320 6 times with a remainder of 210.
The number 6 becomes the next digit in our result. 
Result so far: 66.0
Subtract 4110 from 4320 to get 210.
Fetch the next digit (5) from the dividend, attach it to 210 and continue: 2105 / 685

Moving on to step 6:
The number 685 fits into 2105 3 times, leaving a remainder of 50.
Put 3 as the next digit of the answer. 
Result so far: 663.0
Subtract 2055 from 2105 to get 50.
Include the next digit (8) from the dividend after 50, then repeat: 508 / 685

Going ahead to step 7:
If we divide 508 by 685, we get 0 and a remainder of 508.
Put 0 as the next digit of the answer. 
Result so far: 6630.0
If we take 0 away from 508, we end up with 508.
Grab the next digit (4) from the dividend, add it to 508, then carry on: 5084 / 685

Moving on to step 8:
5084 divided by 685 is 7 with a remainder of 289.
Put 7 as the next digit of the answer. 
Result so far: 66307.0
Deduct 4795 from 5084 and we're left with 289.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2890, and continue the process.

Let's proceed to step 9:
685 goes into 2890 4 times with a remainder of 150.
Use 4 as the next digit of our solution. 
Result so far: 66307.4
The remainder is 150 after subtracting 2740 from 2890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Advancing to step 10:
If we divide 1500 by 685, we get 2 and a remainder of 130.
The next digit of our result is 2. 
Result so far: 66307.42
If we take 1370 away from 1500, we end up with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

On to step 11:
1300 divided by 685 is 1 with a remainder of 615.
The next digit of our result is 1. 
Result so far: 66307.421
If we take 685 away from 1300, we end up with 615.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6150, and continue the process.

Step 12:
The number 685 fits into 6150 8 times, leaving a remainder of 670.
The number 8 becomes the next digit in our result. 
Result so far: 66307.4218
If we take 5480 away from 6150, we end up with 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6700, and continue the process.

Going ahead to step 13:
When dividing 6700 by 685, we get 9 with a remainder of 535.
The next digit of our result is 9. 
Result so far: 66307.42189
Deduct 6165 from 6700 and we're left with 535.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5350, and continue the process.

Advancing to step 14:
685 can be fit into 5350 7 times, resulting in a remainder of 555.
Put 7 as the next digit of the answer. 
Result so far: 66307.421897
The remainder is 555 after subtracting 4795 from 5350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5550, and continue the process.

Moving on to step 15:
If we divide 5550 by 685, we get 8 and a remainder of 70.
The next digit of our result is 8. 
Result so far: 66307.4218978
If we take 5480 away from 5550, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 16:
If we divide 700 by 685, we get 1 and a remainder of 15.
Use 1 as the next digit of our solution. 
Result so far: 66307.42189781
Deduct 685 from 700 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The quotient of the division is 66307.42189781, and the remainder is 1.5e-08.
