Let's divide 639290 by 61
We're looking to find how many times 61 goes into 639290.

Moving on to step 1:
If we divide 6 by 61, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 61

Going ahead to step 2:
If we divide 63 by 61, we get 1 and a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 61 from 63, we get 2.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 61

Step 3:
61 can be fit into 29 0 times, resulting in a remainder of 29.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we subtract 0 from 29, we get 29.
Fetch the next digit (2) from the dividend, attach it to 29 and continue: 292 / 61

Advancing to step 4:
292 divided by 61 is 4 with a remainder of 48.
Put 4 as the next digit of the answer. 
Result so far: 104.0
Subtracting 244 from 292 leaves us with 48.
Include the next digit (9) from the dividend after 48, then repeat: 489 / 61

On to step 5:
The number 61 fits into 489 8 times, leaving a remainder of 1.
The number 8 becomes the next digit in our result. 
Result so far: 1048.0
The remainder is 1 after subtracting 488 from 489.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 61

Let's proceed to step 6:
The number 61 fits into 10 0 times, leaving a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 10480.0
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 7:
When dividing 100 by 61, we get 1 with a remainder of 39.
The number 1 becomes the next digit in our result. 
Result so far: 10480.1
Deduct 61 from 100 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 8:
When dividing 390 by 61, we get 6 with a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 10480.16
The remainder is 24 after subtracting 366 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 9:
The number 61 fits into 240 3 times, leaving a remainder of 57.
Record the quotient 3 as the next digit in the result. 
Result so far: 10480.163
Subtract 183 from 240 to get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Let's proceed to step 10:
570 divided by 61 is 9 with a remainder of 21.
The next digit of our result is 9. 
Result so far: 10480.1639
If we subtract 549 from 570, 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:
61 can be fit into 210 3 times, resulting in a remainder of 27.
The next digit of our result is 3. 
Result so far: 10480.16393
If we subtract 183 from 210, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 12:
If we divide 270 by 61, we get 4 and a remainder of 26.
The next digit of our result is 4. 
Result so far: 10480.163934
The remainder is 26 after subtracting 244 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 13:
When dividing 260 by 61, we get 4 with a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 10480.1639344
Deduct 244 from 260 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

After the division, we end up with 10480.1639344 and a remainder of 1.6e-07.
