54861151 ÷ 986 
Our goal is to divide 54861151 by 986.

Advancing to step 1:
If we divide 5 by 986, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 986

Let's proceed to step 2:
986 goes into 54 0 times with a remainder of 54.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 54, we get 54.
Grab the next digit (8) from the dividend, add it to 54, then carry on: 548 / 986

Let's proceed to step 3:
986 can be fit into 548 0 times, resulting in a remainder of 548.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 548, we get 548.
Include the next digit (6) from the dividend after 548, then repeat: 5486 / 986

Advancing to step 4:
If we divide 5486 by 986, we get 5 and a remainder of 556.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtract 4930 from 5486 to get 556.
Grab the next digit (1) from the dividend, add it to 556, then carry on: 5561 / 986

Step 5:
986 can be fit into 5561 5 times, resulting in a remainder of 631.
The number 5 becomes the next digit in our result. 
Result so far: 55.0
Deduct 4930 from 5561 and we're left with 631.
Append the next digit (1) from the dividend to 631 and continue with: 6311 / 986

Moving on to step 6:
When dividing 6311 by 986, we get 6 with a remainder of 395.
Write down 6 as next digit of the result. 
Result so far: 556.0
Deduct 5916 from 6311 and we're left with 395.
Include the next digit (5) from the dividend after 395, then repeat: 3955 / 986

Moving on to step 7:
If we divide 3955 by 986, we get 4 and a remainder of 11.
Record the quotient 4 as the next digit in the result. 
Result so far: 5564.0
Deduct 3944 from 3955 and we're left with 11.
Grab the next digit (1) from the dividend, add it to 11, then carry on: 111 / 986

Let's proceed to step 8:
If we divide 111 by 986, we get 0 and a remainder of 111.
The next digit of our result is 0. 
Result so far: 55640.0
The remainder is 111 after subtracting 0 from 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Going ahead to step 9:
If we divide 1110 by 986, we get 1 and a remainder of 124.
Write down 1 as next digit of the result. 
Result so far: 55640.1
If we take 986 away from 1110, we end up with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Advancing to step 10:
When dividing 1240 by 986, we get 1 with a remainder of 254.
The number 1 becomes the next digit in our result. 
Result so far: 55640.11
If we take 986 away from 1240, we end up with 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

The final result is 55640.11 with a remainder of 0.254.
