We look at the division of 55643549 by 961 
Let's see how many times 961 fits into 55643549.

Going ahead to step 1:
The number 961 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 961

On to step 2:
When dividing 55 by 961, we get 0 with a remainder of 55.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 55, we get 55.
Append the next digit (6) from the dividend to 55 and continue with: 556 / 961

Advancing to step 3:
556 divided by 961 is 0 with a remainder of 556.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 556 after subtracting 0 from 556.
Fetch the next digit (4) from the dividend, attach it to 556 and continue: 5564 / 961

On to step 4:
If we divide 5564 by 961, we get 5 and a remainder of 759.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we take 4805 away from 5564, we end up with 759.
Fetch the next digit (3) from the dividend, attach it to 759 and continue: 7593 / 961

Step 5:
When dividing 7593 by 961, we get 7 with a remainder of 866.
Use 7 as the next digit of our solution. 
Result so far: 57.0
Subtract 6727 from 7593 to get 866.
Fetch the next digit (5) from the dividend, attach it to 866 and continue: 8665 / 961

On to step 6:
8665 divided by 961 is 9 with a remainder of 16.
Put 9 as the next digit of the answer. 
Result so far: 579.0
If we take 8649 away from 8665, we end up with 16.
Append the next digit (4) from the dividend to 16 and continue with: 164 / 961

On to step 7:
164 divided by 961 is 0 with a remainder of 164.
Record the quotient 0 as the next digit in the result. 
Result so far: 5790.0
Subtracting 0 from 164 leaves us with 164.
Include the next digit (9) from the dividend after 164, then repeat: 1649 / 961

On to step 8:
1649 divided by 961 is 1 with a remainder of 688.
Record the quotient 1 as the next digit in the result. 
Result so far: 57901.0
The remainder is 688 after subtracting 961 from 1649.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6880, and continue the process.

On to step 9:
961 can be fit into 6880 7 times, resulting in a remainder of 153.
Use 7 as the next digit of our solution. 
Result so far: 57901.7
If we subtract 6727 from 6880, we get 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

Let's proceed to step 10:
When dividing 1530 by 961, we get 1 with a remainder of 569.
Record the quotient 1 as the next digit in the result. 
Result so far: 57901.71
The remainder is 569 after subtracting 961 from 1530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5690, and continue the process.

On to step 11:
5690 divided by 961 is 5 with a remainder of 885.
Put 5 as the next digit of the answer. 
Result so far: 57901.715
If we subtract 4805 from 5690, we get 885.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8850, and continue the process.

Moving on to step 12:
8850 divided by 961 is 9 with a remainder of 201.
Write down 9 as next digit of the result. 
Result so far: 57901.7159
If we subtract 8649 from 8850, we get 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

Step 13:
If we divide 2010 by 961, we get 2 and a remainder of 88.
The number 2 becomes the next digit in our result. 
Result so far: 57901.71592
The remainder is 88 after subtracting 1922 from 2010.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Let's proceed to step 14:
The number 961 fits into 880 0 times, leaving a remainder of 880.
Use 0 as the next digit of our solution. 
Result so far: 57901.71592
If we subtract 0 from 880, we get 880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8800, and continue the process.

Moving on to step 15:
961 goes into 8800 9 times with a remainder of 151.
Write down 9 as next digit of the result. 
Result so far: 57901.7159209
If we subtract 8649 from 8800, we get 151.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

On to step 16:
The number 961 fits into 1510 1 times, leaving a remainder of 549.
Record the quotient 1 as the next digit in the result. 
Result so far: 57901.71592091
If we subtract 961 from 1510, we get 549.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5490, and continue the process.

The final outcome is 57901.71592091, with a leftover of 5.49e-07.
