We're dividing 689872 by 42 
We want to divide 689872 by 42.

Let's proceed to step 1:
The number 42 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 42

On to step 2:
68 divided by 42 is 1 with a remainder of 26.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 42 from 68, we get 26.
Fetch the next digit (9) from the dividend, attach it to 26 and continue: 269 / 42

Advancing to step 3:
When dividing 269 by 42, we get 6 with a remainder of 17.
Put 6 as the next digit of the answer. 
Result so far: 16.0
Deduct 252 from 269 and we're left with 17.
Bring next digit (8) of the dividend behind the 17 and repeat the process: 178 / 42

Let's proceed to step 4:
If we divide 178 by 42, we get 4 and a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 164.0
Subtracting 168 from 178 leaves us with 10.
Fetch the next digit (7) from the dividend, attach it to 10 and continue: 107 / 42

Moving on to step 5:
If we divide 107 by 42, we get 2 and a remainder of 23.
Record the quotient 2 as the next digit in the result. 
Result so far: 1642.0
The remainder is 23 after subtracting 84 from 107.
Bring next digit (2) of the dividend behind the 23 and repeat the process: 232 / 42

On to step 6:
42 goes into 232 5 times with a remainder of 22.
The number 5 becomes the next digit in our result. 
Result so far: 16425.0
Subtracting 210 from 232 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 7:
The number 42 fits into 220 5 times, leaving a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 16425.5
Subtract 210 from 220 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
100 divided by 42 is 2 with a remainder of 16.
The next digit of our result is 2. 
Result so far: 16425.52
If we take 84 away from 100, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 9:
160 divided by 42 is 3 with a remainder of 34.
The next digit of our result is 3. 
Result so far: 16425.523
Subtracting 126 from 160 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 10:
The number 42 fits into 340 8 times, leaving a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 16425.5238
Subtract 336 from 340 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 11:
42 goes into 40 0 times with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 16425.5238
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 12:
42 goes into 400 9 times with a remainder of 22.
Record the quotient 9 as the next digit in the result. 
Result so far: 16425.523809
If we subtract 378 from 400, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 13:
If we divide 220 by 42, we get 5 and a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 16425.5238095
If we subtract 210 from 220, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 14:
100 divided by 42 is 2 with a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 16425.52380952
If we subtract 84 from 100, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 16425.52380952, with a leftover of 1.6e-08.
