640764 divided by 61 
We want to figure out the number of times 640764 can be divided by 61.

Step 1:
If we divide 6 by 61, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 61

Going ahead to step 2:
If we divide 64 by 61, we get 1 and a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 3 after subtracting 61 from 64.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 61

Step 3:
If we divide 30 by 61, we get 0 and a remainder of 30.
The next digit of our result is 0. 
Result so far: 10.0
Deduct 0 from 30 and we're left with 30.
Fetch the next digit (7) from the dividend, attach it to 30 and continue: 307 / 61

On to step 4:
The number 61 fits into 307 5 times, leaving a remainder of 2.
Put 5 as the next digit of the answer. 
Result so far: 105.0
The remainder is 2 after subtracting 305 from 307.
Fetch the next digit (6) from the dividend, attach it to 2 and continue: 26 / 61

Going ahead to step 5:
61 can be fit into 26 0 times, resulting in a remainder of 26.
Use 0 as the next digit of our solution. 
Result so far: 1050.0
If we subtract 0 from 26, we get 26.
Include the next digit (4) from the dividend after 26, then repeat: 264 / 61

Let's proceed to step 6:
61 goes into 264 4 times with a remainder of 20.
The next digit of our result is 4. 
Result so far: 10504.0
Subtracting 244 from 264 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 7:
When dividing 200 by 61, we get 3 with a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 10504.3
The remainder is 17 after subtracting 183 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 8:
When dividing 170 by 61, we get 2 with a remainder of 48.
Write down 2 as next digit of the result. 
Result so far: 10504.32
If we take 122 away from 170, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 9:
If we divide 480 by 61, we get 7 and a remainder of 53.
Use 7 as the next digit of our solution. 
Result so far: 10504.327
Subtract 427 from 480 to get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

On to step 10:
When dividing 530 by 61, we get 8 with a remainder of 42.
Put 8 as the next digit of the answer. 
Result so far: 10504.3278
The remainder is 42 after subtracting 488 from 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 11:
61 can be fit into 420 6 times, resulting in a remainder of 54.
Put 6 as the next digit of the answer. 
Result so far: 10504.32786
Subtracting 366 from 420 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 12:
The number 61 fits into 540 8 times, leaving a remainder of 52.
Use 8 as the next digit of our solution. 
Result so far: 10504.327868
If we subtract 488 from 540, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 13:
520 divided by 61 is 8 with a remainder of 32.
Put 8 as the next digit of the answer. 
Result so far: 10504.3278688
Subtract 488 from 520 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The quotient of the division is 10504.3278688, and the remainder is 3.2e-07.
