842142 ÷ 55 
We want to divide 842142 by 55.

On to step 1:
55 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 55

Let's proceed to step 2:
If we divide 84 by 55, we get 1 and a remainder of 29.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 55 from 84, we get 29.
Append the next digit (2) from the dividend to 29 and continue with: 292 / 55

Step 3:
If we divide 292 by 55, we get 5 and a remainder of 17.
The next digit of our result is 5. 
Result so far: 15.0
Deduct 275 from 292 and we're left with 17.
Bring next digit (1) of the dividend behind the 17 and repeat the process: 171 / 55

On to step 4:
55 can be fit into 171 3 times, resulting in a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 153.0
Subtracting 165 from 171 leaves us with 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 55

Going ahead to step 5:
The number 55 fits into 64 1 times, leaving a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 1531.0
The remainder is 9 after subtracting 55 from 64.
Fetch the next digit (2) from the dividend, attach it to 9 and continue: 92 / 55

Going ahead to step 6:
92 divided by 55 is 1 with a remainder of 37.
Write down 1 as next digit of the result. 
Result so far: 15311.0
Subtract 55 from 92 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 7:
When dividing 370 by 55, we get 6 with a remainder of 40.
The number 6 becomes the next digit in our result. 
Result so far: 15311.6
Deduct 330 from 370 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 8:
When dividing 400 by 55, we get 7 with a remainder of 15.
Write down 7 as next digit of the result. 
Result so far: 15311.67
Deduct 385 from 400 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 9:
55 goes into 150 2 times with a remainder of 40.
Record the quotient 2 as the next digit in the result. 
Result so far: 15311.672
Subtract 110 from 150 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 10:
55 can be fit into 400 7 times, resulting in a remainder of 15.
Use 7 as the next digit of our solution. 
Result so far: 15311.6727
The remainder is 15 after subtracting 385 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 11:
150 divided by 55 is 2 with a remainder of 40.
Use 2 as the next digit of our solution. 
Result so far: 15311.67272
The remainder is 40 after subtracting 110 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 12:
55 goes into 400 7 times with a remainder of 15.
Put 7 as the next digit of the answer. 
Result so far: 15311.672727
If we take 385 away from 400, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 13:
55 can be fit into 150 2 times, resulting in a remainder of 40.
Record the quotient 2 as the next digit in the result. 
Result so far: 15311.6727272
If we take 110 away from 150, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 14:
400 divided by 55 is 7 with a remainder of 15.
The number 7 becomes the next digit in our result. 
Result so far: 15311.67272727
Deduct 385 from 400 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The final outcome is 15311.67272727, with a leftover of 1.5e-08.
