We're dividing 762721 by 42 
We want to figure out the number of times 762721 can be divided by 42.

Going ahead to step 1:
42 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (6) from the dividend to 7 and continue with: 76 / 42

On to step 2:
If we divide 76 by 42, we get 1 and a remainder of 34.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 42 from 76, we get 34.
Append the next digit (2) from the dividend to 34 and continue with: 342 / 42

Step 3:
42 can be fit into 342 8 times, resulting in a remainder of 6.
The next digit of our result is 8. 
Result so far: 18.0
Deduct 336 from 342 and we're left with 6.
Include the next digit (7) from the dividend after 6, then repeat: 67 / 42

Advancing to step 4:
The number 42 fits into 67 1 times, leaving a remainder of 25.
The next digit of our result is 1. 
Result so far: 181.0
If we take 42 away from 67, we end up with 25.
Take the next digit (2) from the dividend and append it to 25, then repeat: 252 / 42

On to step 5:
When dividing 252 by 42, we get 6 with a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 1816.0
The remainder is 0 after subtracting 252 from 252.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 42

Going ahead to step 6:
1 divided by 42 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 18160.0
The remainder is 1 after subtracting 0 from 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 7:
If we divide 10 by 42, we get 0 and a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 18160.0
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
The number 42 fits into 100 2 times, leaving a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 18160.02
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.

Step 9:
42 can be fit into 160 3 times, resulting in a remainder of 34.
Use 3 as the next digit of our solution. 
Result so far: 18160.023
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.

Moving on to step 10:
When dividing 340 by 42, we get 8 with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 18160.0238
If we take 336 away from 340, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 11:
42 can be fit into 40 0 times, resulting in a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 18160.0238
If we take 0 away from 40, 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 12:
The number 42 fits into 400 9 times, leaving a remainder of 22.
Use 9 as the next digit of our solution. 
Result so far: 18160.023809
Subtracting 378 from 400 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 13:
The number 42 fits into 220 5 times, leaving a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 18160.0238095
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.

Step 14:
When dividing 100 by 42, we get 2 with a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 18160.02380952
Deduct 84 from 100 and we're left 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.

The quotient of the division is 18160.02380952, and the remainder is 1.6e-08.
