Let's divide 54135977 by 891
We're looking to find how many times 891 goes into 54135977.

On to step 1:
If we divide 5 by 891, we get 0 and a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 891

Going ahead to step 2:
If we divide 54 by 891, we get 0 and a remainder of 54.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 54 to get 54.
Fetch the next digit (1) from the dividend, attach it to 54 and continue: 541 / 891

Moving on to step 3:
When dividing 541 by 891, we get 0 with a remainder of 541.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 541, we end up with 541.
Append the next digit (3) from the dividend to 541 and continue with: 5413 / 891

On to step 4:
If we divide 5413 by 891, we get 6 and a remainder of 67.
Write down 6 as next digit of the result. 
Result so far: 6.0
The remainder is 67 after subtracting 5346 from 5413.
Append the next digit (5) from the dividend to 67 and continue with: 675 / 891

Step 5:
If we divide 675 by 891, we get 0 and a remainder of 675.
Use 0 as the next digit of our solution. 
Result so far: 60.0
Deduct 0 from 675 and we're left with 675.
Grab the next digit (9) from the dividend, add it to 675, then carry on: 6759 / 891

On to step 6:
When dividing 6759 by 891, we get 7 with a remainder of 522.
The next digit of our result is 7. 
Result so far: 607.0
Deduct 6237 from 6759 and we're left with 522.
Include the next digit (7) from the dividend after 522, then repeat: 5227 / 891

Moving on to step 7:
891 can be fit into 5227 5 times, resulting in a remainder of 772.
Record the quotient 5 as the next digit in the result. 
Result so far: 6075.0
Subtracting 4455 from 5227 leaves us with 772.
Take the next digit (7) from the dividend and append it to 772, then repeat: 7727 / 891

On to step 8:
When dividing 7727 by 891, we get 8 with a remainder of 599.
Write down 8 as next digit of the result. 
Result so far: 60758.0
If we take 7128 away from 7727, we end up with 599.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5990, and continue the process.

Going ahead to step 9:
891 goes into 5990 6 times with a remainder of 644.
The next digit of our result is 6. 
Result so far: 60758.6
Subtract 5346 from 5990 to get 644.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6440, and continue the process.

On to step 10:
If we divide 6440 by 891, we get 7 and a remainder of 203.
Write down 7 as next digit of the result. 
Result so far: 60758.67
Subtract 6237 from 6440 to get 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

Let's proceed to step 11:
If we divide 2030 by 891, we get 2 and a remainder of 248.
The next digit of our result is 2. 
Result so far: 60758.672
Deduct 1782 from 2030 and we're left with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Moving on to step 12:
The number 891 fits into 2480 2 times, leaving a remainder of 698.
The next digit of our result is 2. 
Result so far: 60758.6722
Subtract 1782 from 2480 to get 698.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6980, and continue the process.

The final outcome is 60758.6722, with a leftover of 0.00698.
