We divide 604221 by 39
We want to divide 604221 by 39.

Step 1:
39 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (0) of the dividend behind the 6 and repeat the process: 60 / 39

Moving on to step 2:
When dividing 60 by 39, we get 1 with a remainder of 21.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 39 from 60 leaves us with 21.
Grab the next digit (4) from the dividend, add it to 21, then carry on: 214 / 39

Let's proceed to step 3:
If we divide 214 by 39, we get 5 and a remainder of 19.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Deduct 195 from 214 and we're left with 19.
Grab the next digit (2) from the dividend, add it to 19, then carry on: 192 / 39

Let's proceed to step 4:
If we divide 192 by 39, we get 4 and a remainder of 36.
The number 4 becomes the next digit in our result. 
Result so far: 154.0
Deduct 156 from 192 and we're left with 36.
Append the next digit (2) from the dividend to 36 and continue with: 362 / 39

Going ahead to step 5:
39 goes into 362 9 times with a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 1549.0
If we take 351 away from 362, we end up with 11.
Grab the next digit (1) from the dividend, add it to 11, then carry on: 111 / 39

Moving on to step 6:
39 can be fit into 111 2 times, resulting in a remainder of 33.
Use 2 as the next digit of our solution. 
Result so far: 15492.0
The remainder is 33 after subtracting 78 from 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Advancing to step 7:
The number 39 fits into 330 8 times, leaving a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 15492.8
Deduct 312 from 330 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 8:
39 can be fit into 180 4 times, resulting in a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 15492.84
If we take 156 away from 180, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 9:
39 can be fit into 240 6 times, resulting in a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 15492.846
The remainder is 6 after subtracting 234 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 10:
When dividing 60 by 39, we get 1 with a remainder of 21.
The next digit of our result is 1. 
Result so far: 15492.8461
If we subtract 39 from 60, we get 21.
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 11:
When dividing 210 by 39, we get 5 with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 15492.84615
Subtracting 195 from 210 leaves us 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.

Advancing to step 12:
The number 39 fits into 150 3 times, leaving a remainder of 33.
The next digit of our result is 3. 
Result so far: 15492.846153
The remainder is 33 after subtracting 117 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 13:
The number 39 fits into 330 8 times, leaving a remainder of 18.
Put 8 as the next digit of the answer. 
Result so far: 15492.8461538
The remainder is 18 after subtracting 312 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 14:
39 goes into 180 4 times with a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 15492.84615384
Deduct 156 from 180 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final outcome is 15492.84615384, with a leftover of 2.4e-08.
