We look at the division of 42368816 by 420 
Our goal is to divide 42368816 by 420.

Let's proceed to step 1:
If we divide 4 by 420, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 420

Moving on to step 2:
When dividing 42 by 420, we get 0 with a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 42 after subtracting 0 from 42.
Fetch the next digit (3) from the dividend, attach it to 42 and continue: 423 / 420

Step 3:
When dividing 423 by 420, we get 1 with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 420 from 423 to get 3.
Append the next digit (6) from the dividend to 3 and continue with: 36 / 420

Going ahead to step 4:
When dividing 36 by 420, we get 0 with a remainder of 36.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtract 0 from 36 to get 36.
Fetch the next digit (8) from the dividend, attach it to 36 and continue: 368 / 420

Advancing to step 5:
368 divided by 420 is 0 with a remainder of 368.
The number 0 becomes the next digit in our result. 
Result so far: 100.0
If we take 0 away from 368, we end up with 368.
Fetch the next digit (8) from the dividend, attach it to 368 and continue: 3688 / 420

Moving on to step 6:
The number 420 fits into 3688 8 times, leaving a remainder of 328.
Use 8 as the next digit of our solution. 
Result so far: 1008.0
The remainder is 328 after subtracting 3360 from 3688.
Append the next digit (1) from the dividend to 328 and continue with: 3281 / 420

Let's proceed to step 7:
When dividing 3281 by 420, we get 7 with a remainder of 341.
Put 7 as the next digit of the answer. 
Result so far: 10087.0
Subtracting 2940 from 3281 leaves us with 341.
Append the next digit (6) from the dividend to 341 and continue with: 3416 / 420

Advancing to step 8:
The number 420 fits into 3416 8 times, leaving a remainder of 56.
The next digit of our result is 8. 
Result so far: 100878.0
Subtracting 3360 from 3416 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 9:
420 can be fit into 560 1 times, resulting in a remainder of 140.
The next digit of our result is 1. 
Result so far: 100878.1
Deduct 420 from 560 and we're left with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Step 10:
When dividing 1400 by 420, we get 3 with a remainder of 140.
The next digit of our result is 3. 
Result so far: 100878.13
The remainder is 140 after subtracting 1260 from 1400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Let's proceed to step 11:
420 can be fit into 1400 3 times, resulting in a remainder of 140.
Put 3 as the next digit of the answer. 
Result so far: 100878.133
The remainder is 140 after subtracting 1260 from 1400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

The final result is 100878.133 with a remainder of 0.014.
