We look at the division of 39154457 by 684 
We're looking to find how many times 684 goes into 39154457.

Moving on to step 1:
684 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 684

Moving on to step 2:
684 goes into 39 0 times with a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Append the next digit (1) from the dividend to 39 and continue with: 391 / 684

Step 3:
684 goes into 391 0 times with a remainder of 391.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 391 to get 391.
Fetch the next digit (5) from the dividend, attach it to 391 and continue: 3915 / 684

On to step 4:
The number 684 fits into 3915 5 times, leaving a remainder of 495.
Put 5 as the next digit of the answer. 
Result so far: 5.0
The remainder is 495 after subtracting 3420 from 3915.
Take the next digit (4) from the dividend and append it to 495, then repeat: 4954 / 684

On to step 5:
684 goes into 4954 7 times with a remainder of 166.
Record the quotient 7 as the next digit in the result. 
Result so far: 57.0
If we subtract 4788 from 4954, we get 166.
Grab the next digit (4) from the dividend, add it to 166, then carry on: 1664 / 684

Advancing to step 6:
1664 divided by 684 is 2 with a remainder of 296.
The number 2 becomes the next digit in our result. 
Result so far: 572.0
If we subtract 1368 from 1664, we get 296.
Include the next digit (5) from the dividend after 296, then repeat: 2965 / 684

Let's proceed to step 7:
If we divide 2965 by 684, we get 4 and a remainder of 229.
Use 4 as the next digit of our solution. 
Result so far: 5724.0
If we subtract 2736 from 2965, we get 229.
Take the next digit (7) from the dividend and append it to 229, then repeat: 2297 / 684

Step 8:
684 can be fit into 2297 3 times, resulting in a remainder of 245.
Write down 3 as next digit of the result. 
Result so far: 57243.0
The remainder is 245 after subtracting 2052 from 2297.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Advancing to step 9:
2450 divided by 684 is 3 with a remainder of 398.
Record the quotient 3 as the next digit in the result. 
Result so far: 57243.3
If we take 2052 away from 2450, we end up with 398.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

Step 10:
The number 684 fits into 3980 5 times, leaving a remainder of 560.
Record the quotient 5 as the next digit in the result. 
Result so far: 57243.35
Deduct 3420 from 3980 and we're left with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Let's proceed to step 11:
When dividing 5600 by 684, we get 8 with a remainder of 128.
Write down 8 as next digit of the result. 
Result so far: 57243.358
Subtract 5472 from 5600 to get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Let's proceed to step 12:
1280 divided by 684 is 1 with a remainder of 596.
The number 1 becomes the next digit in our result. 
Result so far: 57243.3581
Deduct 684 from 1280 and we're left with 596.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

Going ahead to step 13:
684 goes into 5960 8 times with a remainder of 488.
Write down 8 as next digit of the result. 
Result so far: 57243.35818
If we subtract 5472 from 5960, we get 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

Step 14:
684 goes into 4880 7 times with a remainder of 92.
Put 7 as the next digit of the answer. 
Result so far: 57243.358187
If we subtract 4788 from 4880, we get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Going ahead to step 15:
684 can be fit into 920 1 times, resulting in a remainder of 236.
The number 1 becomes the next digit in our result. 
Result so far: 57243.3581871
If we take 684 away from 920, we end up with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Going ahead to step 16:
When dividing 2360 by 684, we get 3 with a remainder of 308.
Put 3 as the next digit of the answer. 
Result so far: 57243.35818713
Subtract 2052 from 2360 to get 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

After the division, we end up with 57243.35818713 and a remainder of 3.08e-07.
