We divide 55621457 by 646
Let's see how many times 646 fits into 55621457.

Let's proceed to step 1:
646 goes into 5 0 times with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Grab the next digit (5) from the dividend, add it to 5, then carry on: 55 / 646

Going ahead to step 2:
The number 646 fits into 55 0 times, leaving a remainder of 55.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 55 leaves us with 55.
Fetch the next digit (6) from the dividend, attach it to 55 and continue: 556 / 646

Advancing to step 3:
The number 646 fits into 556 0 times, leaving a remainder of 556.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 556, we get 556.
Fetch the next digit (2) from the dividend, attach it to 556 and continue: 5562 / 646

Going ahead to step 4:
646 goes into 5562 8 times with a remainder of 394.
The next digit of our result is 8. 
Result so far: 8.0
Subtracting 5168 from 5562 leaves us with 394.
Bring next digit (1) of the dividend behind the 394 and repeat the process: 3941 / 646

Let's proceed to step 5:
The number 646 fits into 3941 6 times, leaving a remainder of 65.
Use 6 as the next digit of our solution. 
Result so far: 86.0
If we subtract 3876 from 3941, we get 65.
Take the next digit (4) from the dividend and append it to 65, then repeat: 654 / 646

Moving on to step 6:
The number 646 fits into 654 1 times, leaving a remainder of 8.
The next digit of our result is 1. 
Result so far: 861.0
If we subtract 646 from 654, we get 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 646

Let's proceed to step 7:
646 can be fit into 85 0 times, resulting in a remainder of 85.
Put 0 as the next digit of the answer. 
Result so far: 8610.0
The remainder is 85 after subtracting 0 from 85.
Grab the next digit (7) from the dividend, add it to 85, then carry on: 857 / 646

Let's proceed to step 8:
When dividing 857 by 646, we get 1 with a remainder of 211.
The next digit of our result is 1. 
Result so far: 86101.0
If we subtract 646 from 857, we get 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

Going ahead to step 9:
2110 divided by 646 is 3 with a remainder of 172.
The next digit of our result is 3. 
Result so far: 86101.3
If we subtract 1938 from 2110, we get 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Moving on to step 10:
The number 646 fits into 1720 2 times, leaving a remainder of 428.
Record the quotient 2 as the next digit in the result. 
Result so far: 86101.32
If we take 1292 away from 1720, we end up with 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

On to step 11:
The number 646 fits into 4280 6 times, leaving a remainder of 404.
Use 6 as the next digit of our solution. 
Result so far: 86101.326
Subtract 3876 from 4280 to get 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Advancing to step 12:
4040 divided by 646 is 6 with a remainder of 164.
Record the quotient 6 as the next digit in the result. 
Result so far: 86101.3266
Deduct 3876 from 4040 and we're left with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

The quotient of the division is 86101.3266, and the remainder is 0.00164.
