We look at the division of 40552430 by 684 
Let's see how many times 684 fits into 40552430.

Moving on to step 1:
684 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 (0) from the dividend, add it to 4, then carry on: 40 / 684

Advancing to step 2:
40 divided by 684 is 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 40, we end up with 40.
Include the next digit (5) from the dividend after 40, then repeat: 405 / 684

Moving on to step 3:
684 goes into 405 0 times with a remainder of 405.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 405 and we're left with 405.
Append the next digit (5) from the dividend to 405 and continue with: 4055 / 684

On to step 4:
If we divide 4055 by 684, we get 5 and a remainder of 635.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we subtract 3420 from 4055, we get 635.
Append the next digit (2) from the dividend to 635 and continue with: 6352 / 684

Advancing to step 5:
684 goes into 6352 9 times with a remainder of 196.
Record the quotient 9 as the next digit in the result. 
Result so far: 59.0
Deduct 6156 from 6352 and we're left with 196.
Include the next digit (4) from the dividend after 196, then repeat: 1964 / 684

On to step 6:
684 goes into 1964 2 times with a remainder of 596.
Put 2 as the next digit of the answer. 
Result so far: 592.0
If we take 1368 away from 1964, we end up with 596.
Append the next digit (3) from the dividend to 596 and continue with: 5963 / 684

Advancing to step 7:
If we divide 5963 by 684, we get 8 and a remainder of 491.
Put 8 as the next digit of the answer. 
Result so far: 5928.0
Deduct 5472 from 5963 and we're left with 491.
Take the next digit (0) from the dividend and append it to 491, then repeat: 4910 / 684

Let's proceed to step 8:
684 goes into 4910 7 times with a remainder of 122.
The number 7 becomes the next digit in our result. 
Result so far: 59287.0
Subtracting 4788 from 4910 leaves us with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Advancing to step 9:
If we divide 1220 by 684, we get 1 and a remainder of 536.
The next digit of our result is 1. 
Result so far: 59287.1
The remainder is 536 after subtracting 684 from 1220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5360, and continue the process.

Let's proceed to step 10:
The number 684 fits into 5360 7 times, leaving a remainder of 572.
Put 7 as the next digit of the answer. 
Result so far: 59287.17
Subtract 4788 from 5360 to get 572.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5720, and continue the process.

Advancing to step 11:
684 can be fit into 5720 8 times, resulting in a remainder of 248.
Record the quotient 8 as the next digit in the result. 
Result so far: 59287.178
Subtracting 5472 from 5720 leaves us with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Going ahead to step 12:
When dividing 2480 by 684, we get 3 with a remainder of 428.
Write down 3 as next digit of the result. 
Result so far: 59287.1783
The remainder is 428 after subtracting 2052 from 2480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

On to step 13:
684 goes into 4280 6 times with a remainder of 176.
The next digit of our result is 6. 
Result so far: 59287.17836
The remainder is 176 after subtracting 4104 from 4280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

On to step 14:
684 goes into 1760 2 times with a remainder of 392.
The next digit of our result is 2. 
Result so far: 59287.178362
If we take 1368 away from 1760, we end up with 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

On to step 15:
When dividing 3920 by 684, we get 5 with a remainder of 500.
Use 5 as the next digit of our solution. 
Result so far: 59287.1783625
Subtract 3420 from 3920 to get 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

On to step 16:
684 goes into 5000 7 times with a remainder of 212.
Use 7 as the next digit of our solution. 
Result so far: 59287.17836257
Subtracting 4788 from 5000 leaves us with 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

The quotient of the division is 59287.17836257, and the remainder is 2.12e-07.
