55638821 ÷ 891 
We want to figure out the number of times 55638821 can be divided by 891.

Let's proceed to step 1:
891 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 891

Moving on to step 2:
891 goes into 55 0 times with a remainder of 55.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 55 to get 55.
Take the next digit (6) from the dividend and append it to 55, then repeat: 556 / 891

Advancing to step 3:
891 can be fit into 556 0 times, resulting in 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.
Grab the next digit (3) from the dividend, add it to 556, then carry on: 5563 / 891

On to step 4:
5563 divided by 891 is 6 with a remainder of 217.
The next digit of our result is 6. 
Result so far: 6.0
Subtracting 5346 from 5563 leaves us with 217.
Fetch the next digit (8) from the dividend, attach it to 217 and continue: 2178 / 891

Step 5:
If we divide 2178 by 891, we get 2 and a remainder of 396.
Record the quotient 2 as the next digit in the result. 
Result so far: 62.0
If we take 1782 away from 2178, we end up with 396.
Include the next digit (8) from the dividend after 396, then repeat: 3968 / 891

On to step 6:
3968 divided by 891 is 4 with a remainder of 404.
Write down 4 as next digit of the result. 
Result so far: 624.0
If we take 3564 away from 3968, we end up with 404.
Bring next digit (2) of the dividend behind the 404 and repeat the process: 4042 / 891

Going ahead to step 7:
891 can be fit into 4042 4 times, resulting in a remainder of 478.
Record the quotient 4 as the next digit in the result. 
Result so far: 6244.0
Subtract 3564 from 4042 to get 478.
Grab the next digit (1) from the dividend, add it to 478, then carry on: 4781 / 891

On to step 8:
891 goes into 4781 5 times with a remainder of 326.
Write down 5 as next digit of the result. 
Result so far: 62445.0
If we take 4455 away from 4781, we end up with 326.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

Advancing to step 9:
The number 891 fits into 3260 3 times, leaving a remainder of 587.
Put 3 as the next digit of the answer. 
Result so far: 62445.3
Subtract 2673 from 3260 to get 587.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5870, and continue the process.

Step 10:
891 can be fit into 5870 6 times, resulting in a remainder of 524.
The next digit of our result is 6. 
Result so far: 62445.36
The remainder is 524 after subtracting 5346 from 5870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5240, and continue the process.

Step 11:
When dividing 5240 by 891, we get 5 with a remainder of 785.
Record the quotient 5 as the next digit in the result. 
Result so far: 62445.365
Subtract 4455 from 5240 to get 785.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7850, and continue the process.

Advancing to step 12:
891 goes into 7850 8 times with a remainder of 722.
Use 8 as the next digit of our solution. 
Result so far: 62445.3658
Subtract 7128 from 7850 to get 722.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7220, and continue the process.

Moving on to step 13:
891 can be fit into 7220 8 times, resulting in a remainder of 92.
Write down 8 as next digit of the result. 
Result so far: 62445.36588
If we subtract 7128 from 7220, we get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

The final result is 62445.36588 with a remainder of 9.2e-05.
