We divide 3685921 by 725
We're looking to find how many times 725 goes into 3685921.

On to step 1:
725 can be fit into 3 0 times, resulting in a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (6) of the dividend behind the 3 and repeat the process: 36 / 725

On to step 2:
725 goes into 36 0 times with a remainder of 36.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 36, we get 36.
Grab the next digit (8) from the dividend, add it to 36, then carry on: 368 / 725

Step 3:
When dividing 368 by 725, we get 0 with a remainder of 368.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 368 after subtracting 0 from 368.
Bring next digit (5) of the dividend behind the 368 and repeat the process: 3685 / 725

Going ahead to step 4:
When dividing 3685 by 725, we get 5 with a remainder of 60.
Put 5 as the next digit of the answer. 
Result so far: 5.0
The remainder is 60 after subtracting 3625 from 3685.
Append the next digit (9) from the dividend to 60 and continue with: 609 / 725

Going ahead to step 5:
725 goes into 609 0 times with a remainder of 609.
Put 0 as the next digit of the answer. 
Result so far: 50.0
Deduct 0 from 609 and we're left with 609.
Take the next digit (2) from the dividend and append it to 609, then repeat: 6092 / 725

Advancing to step 6:
If we divide 6092 by 725, we get 8 and a remainder of 292.
Write down 8 as next digit of the result. 
Result so far: 508.0
Subtracting 5800 from 6092 leaves us with 292.
Include the next digit (1) from the dividend after 292, then repeat: 2921 / 725

Let's proceed to step 7:
725 goes into 2921 4 times with a remainder of 21.
The next digit of our result is 4. 
Result so far: 5084.0
The remainder is 21 after subtracting 2900 from 2921.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 8:
When dividing 210 by 725, we get 0 with a remainder of 210.
The next digit of our result is 0. 
Result so far: 5084.0
Subtract 0 from 210 to get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Step 9:
The number 725 fits into 2100 2 times, leaving a remainder of 650.
Use 2 as the next digit of our solution. 
Result so far: 5084.02
If we take 1450 away from 2100, we end up with 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

Step 10:
6500 divided by 725 is 8 with a remainder of 700.
Use 8 as the next digit of our solution. 
Result so far: 5084.028
If we take 5800 away from 6500, we end up with 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

On to step 11:
If we divide 7000 by 725, we get 9 and a remainder of 475.
Use 9 as the next digit of our solution. 
Result so far: 5084.0289
Subtracting 6525 from 7000 leaves us with 475.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4750, and continue the process.

On to step 12:
The number 725 fits into 4750 6 times, leaving a remainder of 400.
The number 6 becomes the next digit in our result. 
Result so far: 5084.02896
If we take 4350 away from 4750, we end up with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Let's proceed to step 13:
725 can be fit into 4000 5 times, resulting in a remainder of 375.
The number 5 becomes the next digit in our result. 
Result so far: 5084.028965
Subtracting 3625 from 4000 leaves us with 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Moving on to step 14:
If we divide 3750 by 725, we get 5 and a remainder of 125.
Record the quotient 5 as the next digit in the result. 
Result so far: 5084.0289655
The remainder is 125 after subtracting 3625 from 3750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

The final result is 5084.0289655 with a remainder of 1.25e-06.
