658435 ÷ 42 
We want to figure out the number of times 658435 can be divided by 42.

Going ahead to step 1:
If we divide 6 by 42, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (5) from the dividend, add it to 6, then carry on: 65 / 42

Advancing to step 2:
42 can be fit into 65 1 times, resulting in a remainder of 23.
The next digit of our result is 1. 
Result so far: 1.0
If we take 42 away from 65, we end up with 23.
Bring next digit (8) of the dividend behind the 23 and repeat the process: 238 / 42

Advancing to step 3:
The number 42 fits into 238 5 times, leaving a remainder of 28.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Deduct 210 from 238 and we're left with 28.
Take the next digit (4) from the dividend and append it to 28, then repeat: 284 / 42

Step 4:
284 divided by 42 is 6 with a remainder of 32.
Write down 6 as next digit of the result. 
Result so far: 156.0
If we subtract 252 from 284, we get 32.
Grab the next digit (3) from the dividend, add it to 32, then carry on: 323 / 42

Moving on to step 5:
If we divide 323 by 42, we get 7 and a remainder of 29.
Use 7 as the next digit of our solution. 
Result so far: 1567.0
If we subtract 294 from 323, we get 29.
Append the next digit (5) from the dividend to 29 and continue with: 295 / 42

Let's proceed to step 6:
42 can be fit into 295 7 times, resulting in a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 15677.0
Subtract 294 from 295 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
42 can be fit into 10 0 times, resulting in a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 15677.0
The remainder is 10 after subtracting 0 from 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:
If we divide 100 by 42, we get 2 and a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 15677.02
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.

Advancing to step 9:
When dividing 160 by 42, we get 3 with a remainder of 34.
Use 3 as the next digit of our solution. 
Result so far: 15677.023
Subtract 126 from 160 to 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.

Let's proceed to step 10:
42 can be fit into 340 8 times, resulting in a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 15677.0238
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.

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: 15677.0238
Deduct 0 from 40 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.

Let's proceed to step 12:
400 divided by 42 is 9 with a remainder of 22.
Use 9 as the next digit of our solution. 
Result so far: 15677.023809
If we take 378 away from 400, we end up 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.

Moving on to step 13:
The number 42 fits into 220 5 times, leaving a remainder of 10.
The next digit of our result is 5. 
Result so far: 15677.0238095
If we take 210 away from 220, we end up 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 14:
100 divided by 42 is 2 with a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 15677.02380952
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.

The quotient of the division is 15677.02380952, and the remainder is 1.6e-08.
