30783053 divided by 420 
We're looking to find how many times 420 goes into 30783053.

Advancing to step 1:
When dividing 3 by 420, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 420

Moving on to step 2:
The number 420 fits into 30 0 times, leaving a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 30 and we're left with 30.
Take the next digit (7) from the dividend and append it to 30, then repeat: 307 / 420

Moving on to step 3:
307 divided by 420 is 0 with a remainder of 307.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 307 leaves us with 307.
Take the next digit (8) from the dividend and append it to 307, then repeat: 3078 / 420

Step 4:
3078 divided by 420 is 7 with a remainder of 138.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Deduct 2940 from 3078 and we're left with 138.
Include the next digit (3) from the dividend after 138, then repeat: 1383 / 420

Let's proceed to step 5:
420 can be fit into 1383 3 times, resulting in a remainder of 123.
Record the quotient 3 as the next digit in the result. 
Result so far: 73.0
The remainder is 123 after subtracting 1260 from 1383.
Take the next digit (0) from the dividend and append it to 123, then repeat: 1230 / 420

On to step 6:
When dividing 1230 by 420, we get 2 with a remainder of 390.
Use 2 as the next digit of our solution. 
Result so far: 732.0
The remainder is 390 after subtracting 840 from 1230.
Include the next digit (5) from the dividend after 390, then repeat: 3905 / 420

Advancing to step 7:
The number 420 fits into 3905 9 times, leaving a remainder of 125.
The next digit of our result is 9. 
Result so far: 7329.0
If we subtract 3780 from 3905, we get 125.
Include the next digit (3) from the dividend after 125, then repeat: 1253 / 420

Step 8:
When dividing 1253 by 420, we get 2 with a remainder of 413.
Use 2 as the next digit of our solution. 
Result so far: 73292.0
Subtracting 840 from 1253 leaves us with 413.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4130, and continue the process.

Going ahead to step 9:
4130 divided by 420 is 9 with a remainder of 350.
Write down 9 as next digit of the result. 
Result so far: 73292.9
The remainder is 350 after subtracting 3780 from 4130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

On to step 10:
420 goes into 3500 8 times with a remainder of 140.
The next digit of our result is 8. 
Result so far: 73292.98
Deduct 3360 from 3500 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 11:
When dividing 1400 by 420, we get 3 with a remainder of 140.
Put 3 as the next digit of the answer. 
Result so far: 73292.983
Subtracting 1260 from 1400 leaves us 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 12:
420 can be fit into 1400 3 times, resulting in a remainder of 140.
The number 3 becomes the next digit in our result. 
Result so far: 73292.9833
Deduct 1260 from 1400 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.

After the division, we end up with 73292.9833 and a remainder of 0.0014.
