We look at the division of 691378 by 42 
Our goal is to divide 691378 by 42.

Going ahead to step 1:
When dividing 6 by 42, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 42

Advancing to step 2:
When dividing 69 by 42, we get 1 with a remainder of 27.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 42 from 69 and we're left with 27.
Take the next digit (1) from the dividend and append it to 27, then repeat: 271 / 42

Step 3:
271 divided by 42 is 6 with a remainder of 19.
Use 6 as the next digit of our solution. 
Result so far: 16.0
Subtract 252 from 271 to get 19.
Include the next digit (3) from the dividend after 19, then repeat: 193 / 42

Moving on to step 4:
If we divide 193 by 42, we get 4 and a remainder of 25.
The number 4 becomes the next digit in our result. 
Result so far: 164.0
Subtracting 168 from 193 leaves us with 25.
Grab the next digit (7) from the dividend, add it to 25, then carry on: 257 / 42

On to step 5:
42 can be fit into 257 6 times, resulting in a remainder of 5.
Record the quotient 6 as the next digit in the result. 
Result so far: 1646.0
If we take 252 away from 257, we end up with 5.
Append the next digit (8) from the dividend to 5 and continue with: 58 / 42

Going ahead to step 6:
The number 42 fits into 58 1 times, leaving a remainder of 16.
Use 1 as the next digit of our solution. 
Result so far: 16461.0
The remainder is 16 after subtracting 42 from 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 7:
42 can be fit into 160 3 times, resulting in a remainder of 34.
The number 3 becomes the next digit in our result. 
Result so far: 16461.3
If we subtract 126 from 160, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 8:
340 divided by 42 is 8 with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 16461.38
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.

Moving on to step 9:
42 goes into 40 0 times with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 16461.38
If we subtract 0 from 40, we 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.

Moving on to step 10:
42 can be fit into 400 9 times, resulting in a remainder of 22.
Put 9 as the next digit of the answer. 
Result so far: 16461.3809
Subtract 378 from 400 to 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.

Let's proceed to step 11:
If we divide 220 by 42, we get 5 and a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 16461.38095
Subtracting 210 from 220 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.

Advancing to step 12:
42 can be fit into 100 2 times, resulting in a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 16461.380952
The remainder is 16 after subtracting 84 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 13:
When dividing 160 by 42, we get 3 with a remainder of 34.
The number 3 becomes the next digit in our result. 
Result so far: 16461.3809523
If we subtract 126 from 160, we get 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 14:
340 divided by 42 is 8 with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 16461.38095238
Deduct 336 from 340 and we're left 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.

After the division, we end up with 16461.38095238 and a remainder of 4e-09.
