Let's divide 56647554 by 646
Our goal is to divide 56647554 by 646.

Going ahead to step 1:
646 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Fetch the next digit (6) from the dividend, attach it to 5 and continue: 56 / 646

Moving on to step 2:
The number 646 fits into 56 0 times, leaving a remainder of 56.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 56 to get 56.
Append the next digit (6) from the dividend to 56 and continue with: 566 / 646

Advancing to step 3:
The number 646 fits into 566 0 times, leaving a remainder of 566.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 566 and we're left with 566.
Bring next digit (4) of the dividend behind the 566 and repeat the process: 5664 / 646

Advancing to step 4:
5664 divided by 646 is 8 with a remainder of 496.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtracting 5168 from 5664 leaves us with 496.
Take the next digit (7) from the dividend and append it to 496, then repeat: 4967 / 646

Moving on to step 5:
The number 646 fits into 4967 7 times, leaving a remainder of 445.
Record the quotient 7 as the next digit in the result. 
Result so far: 87.0
Deduct 4522 from 4967 and we're left with 445.
Include the next digit (5) from the dividend after 445, then repeat: 4455 / 646

Let's proceed to step 6:
The number 646 fits into 4455 6 times, leaving a remainder of 579.
The number 6 becomes the next digit in our result. 
Result so far: 876.0
If we take 3876 away from 4455, we end up with 579.
Grab the next digit (5) from the dividend, add it to 579, then carry on: 5795 / 646

Step 7:
646 can be fit into 5795 8 times, resulting in a remainder of 627.
The next digit of our result is 8. 
Result so far: 8768.0
Deduct 5168 from 5795 and we're left with 627.
Append the next digit (4) from the dividend to 627 and continue with: 6274 / 646

Let's proceed to step 8:
6274 divided by 646 is 9 with a remainder of 460.
The next digit of our result is 9. 
Result so far: 87689.0
If we take 5814 away from 6274, we end up with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Going ahead to step 9:
646 goes into 4600 7 times with a remainder of 78.
Put 7 as the next digit of the answer. 
Result so far: 87689.7
If we take 4522 away from 4600, we end up with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Going ahead to step 10:
The number 646 fits into 780 1 times, leaving a remainder of 134.
Write down 1 as next digit of the result. 
Result so far: 87689.71
Deduct 646 from 780 and we're left with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Advancing to step 11:
646 can be fit into 1340 2 times, resulting in a remainder of 48.
Put 2 as the next digit of the answer. 
Result so far: 87689.712
If we take 1292 away from 1340, 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.

On to step 12:
646 can be fit into 480 0 times, resulting in a remainder of 480.
The next digit of our result is 0. 
Result so far: 87689.712
The remainder is 480 after subtracting 0 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Advancing to step 13:
646 can be fit into 4800 7 times, resulting in a remainder of 278.
The next digit of our result is 7. 
Result so far: 87689.71207
The remainder is 278 after subtracting 4522 from 4800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

Moving on to step 14:
When dividing 2780 by 646, we get 4 with a remainder of 196.
Put 4 as the next digit of the answer. 
Result so far: 87689.712074
If we subtract 2584 from 2780, we get 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

On to step 15:
If we divide 1960 by 646, we get 3 and a remainder of 22.
Record the quotient 3 as the next digit in the result. 
Result so far: 87689.7120743
If we take 1938 away from 1960, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 16:
The number 646 fits into 220 0 times, leaving a remainder of 220.
Put 0 as the next digit of the answer. 
Result so far: 87689.7120743
Subtracting 0 from 220 leaves us with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

After the division, we end up with 87689.7120743 and a remainder of 2.2e-07.
