Let's divide 61806643 by 646
Our goal is to divide 61806643 by 646.

On to step 1:
646 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (1) from the dividend and append it to 6, then repeat: 61 / 646

Going ahead to step 2:
61 divided by 646 is 0 with a remainder of 61.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 61 leaves us with 61.
Take the next digit (8) from the dividend and append it to 61, then repeat: 618 / 646

On to step 3:
If we divide 618 by 646, we get 0 and a remainder of 618.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 618, we end up with 618.
Append the next digit (0) from the dividend to 618 and continue with: 6180 / 646

Moving on to step 4:
If we divide 6180 by 646, we get 9 and a remainder of 366.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we subtract 5814 from 6180, we get 366.
Fetch the next digit (6) from the dividend, attach it to 366 and continue: 3666 / 646

Advancing to step 5:
If we divide 3666 by 646, we get 5 and a remainder of 436.
The next digit of our result is 5. 
Result so far: 95.0
The remainder is 436 after subtracting 3230 from 3666.
Bring next digit (6) of the dividend behind the 436 and repeat the process: 4366 / 646

Let's proceed to step 6:
4366 divided by 646 is 6 with a remainder of 490.
Write down 6 as next digit of the result. 
Result so far: 956.0
Deduct 3876 from 4366 and we're left with 490.
Take the next digit (4) from the dividend and append it to 490, then repeat: 4904 / 646

Going ahead to step 7:
The number 646 fits into 4904 7 times, leaving a remainder of 382.
The next digit of our result is 7. 
Result so far: 9567.0
The remainder is 382 after subtracting 4522 from 4904.
Append the next digit (3) from the dividend to 382 and continue with: 3823 / 646

Going ahead to step 8:
If we divide 3823 by 646, we get 5 and a remainder of 593.
Write down 5 as next digit of the result. 
Result so far: 95675.0
If we take 3230 away from 3823, we end up with 593.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5930, and continue the process.

Advancing to step 9:
5930 divided by 646 is 9 with a remainder of 116.
Write down 9 as next digit of the result. 
Result so far: 95675.9
Subtract 5814 from 5930 to get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Going ahead to step 10:
1160 divided by 646 is 1 with a remainder of 514.
Write down 1 as next digit of the result. 
Result so far: 95675.91
Subtracting 646 from 1160 leaves us with 514.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5140, and continue the process.

Moving on to step 11:
646 can be fit into 5140 7 times, resulting in a remainder of 618.
The number 7 becomes the next digit in our result. 
Result so far: 95675.917
The remainder is 618 after subtracting 4522 from 5140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6180, and continue the process.

Advancing to step 12:
646 goes into 6180 9 times with a remainder of 366.
Use 9 as the next digit of our solution. 
Result so far: 95675.9179
If we take 5814 away from 6180, we end up with 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

On to step 13:
646 goes into 3660 5 times with a remainder of 430.
Write down 5 as next digit of the result. 
Result so far: 95675.91795
Subtract 3230 from 3660 to get 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Advancing to step 14:
The number 646 fits into 4300 6 times, leaving a remainder of 424.
Record the quotient 6 as the next digit in the result. 
Result so far: 95675.917956
If we subtract 3876 from 4300, we get 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

Let's proceed to step 15:
When dividing 4240 by 646, we get 6 with a remainder of 364.
Use 6 as the next digit of our solution. 
Result so far: 95675.9179566
If we subtract 3876 from 4240, we get 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

The final result is 95675.9179566 with a remainder of 3.64e-06.
