Let's divide 640390 by 61
We want to divide 640390 by 61.

Let's proceed to step 1:
61 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
Subtracting 0 from 6 leaves us with 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 61

On to step 2:
If we divide 64 by 61, we get 1 and a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 61 away from 64, we end up with 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 61

Let's proceed to step 3:
30 divided by 61 is 0 with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we subtract 0 from 30, we get 30.
Bring next digit (3) of the dividend behind the 30 and repeat the process: 303 / 61

Advancing to step 4:
61 goes into 303 4 times with a remainder of 59.
Write down 4 as next digit of the result. 
Result so far: 104.0
Subtract 244 from 303 to get 59.
Bring next digit (9) of the dividend behind the 59 and repeat the process: 599 / 61

Advancing to step 5:
If we divide 599 by 61, we get 9 and a remainder of 50.
Record the quotient 9 as the next digit in the result. 
Result so far: 1049.0
If we take 549 away from 599, we end up with 50.
Grab the next digit (0) from the dividend, add it to 50, then carry on: 500 / 61

Let's proceed to step 6:
When dividing 500 by 61, we get 8 with a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 10498.0
The remainder is 12 after subtracting 488 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 7:
61 can be fit into 120 1 times, resulting in a remainder of 59.
Use 1 as the next digit of our solution. 
Result so far: 10498.1
Deduct 61 from 120 and we're left with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Let's proceed to step 8:
When dividing 590 by 61, we get 9 with a remainder of 41.
The next digit of our result is 9. 
Result so far: 10498.19
Deduct 549 from 590 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Step 9:
61 can be fit into 410 6 times, resulting in a remainder of 44.
Write down 6 as next digit of the result. 
Result so far: 10498.196
The remainder is 44 after subtracting 366 from 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 10:
If we divide 440 by 61, we get 7 and a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 10498.1967
If we take 427 away from 440, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 11:
If we divide 130 by 61, we get 2 and a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 10498.19672
Subtract 122 from 130 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 12:
The number 61 fits into 80 1 times, leaving a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 10498.196721
If we take 61 away from 80, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 13:
61 can be fit into 190 3 times, resulting in a remainder of 7.
The next digit of our result is 3. 
Result so far: 10498.1967213
If we take 183 away from 190, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 14:
When dividing 70 by 61, we get 1 with a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 10498.19672131
If we subtract 61 from 70, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Our division results in 10498.19672131 with a remaining 9e-09.
