We look at the division of 39643887 by 590 
We want to divide 39643887 by 590.

Going ahead to step 1:
When dividing 3 by 590, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 590

Going ahead to step 2:
39 divided by 590 is 0 with a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Bring next digit (6) of the dividend behind the 39 and repeat the process: 396 / 590

Advancing to step 3:
590 goes into 396 0 times with a remainder of 396.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 396 and we're left with 396.
Grab the next digit (4) from the dividend, add it to 396, then carry on: 3964 / 590

Step 4:
590 goes into 3964 6 times with a remainder of 424.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtracting 3540 from 3964 leaves us with 424.
Bring next digit (3) of the dividend behind the 424 and repeat the process: 4243 / 590

Step 5:
590 can be fit into 4243 7 times, resulting in a remainder of 113.
The number 7 becomes the next digit in our result. 
Result so far: 67.0
Subtracting 4130 from 4243 leaves us with 113.
Take the next digit (8) from the dividend and append it to 113, then repeat: 1138 / 590

Let's proceed to step 6:
The number 590 fits into 1138 1 times, leaving a remainder of 548.
Record the quotient 1 as the next digit in the result. 
Result so far: 671.0
The remainder is 548 after subtracting 590 from 1138.
Grab the next digit (8) from the dividend, add it to 548, then carry on: 5488 / 590

Step 7:
5488 divided by 590 is 9 with a remainder of 178.
Record the quotient 9 as the next digit in the result. 
Result so far: 6719.0
The remainder is 178 after subtracting 5310 from 5488.
Grab the next digit (7) from the dividend, add it to 178, then carry on: 1787 / 590

Let's proceed to step 8:
590 goes into 1787 3 times with a remainder of 17.
The next digit of our result is 3. 
Result so far: 67193.0
Subtracting 1770 from 1787 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 9:
If we divide 170 by 590, we get 0 and a remainder of 170.
Put 0 as the next digit of the answer. 
Result so far: 67193.0
Subtract 0 from 170 to get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Advancing to step 10:
The number 590 fits into 1700 2 times, leaving a remainder of 520.
Put 2 as the next digit of the answer. 
Result so far: 67193.02
If we subtract 1180 from 1700, we get 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Let's proceed to step 11:
590 goes into 5200 8 times with a remainder of 480.
Put 8 as the next digit of the answer. 
Result so far: 67193.028
If we take 4720 away from 5200, we end up with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Going ahead to step 12:
When dividing 4800 by 590, we get 8 with a remainder of 80.
Record the quotient 8 as the next digit in the result. 
Result so far: 67193.0288
If we take 4720 away from 4800, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

The final result is 67193.0288 with a remainder of 0.0008.
