We divide 64830283 by 420
Let's see how many times 420 fits into 64830283.

Advancing to step 1:
420 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 420

Step 2:
When dividing 64 by 420, we get 0 with a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 64 to get 64.
Bring next digit (8) of the dividend behind the 64 and repeat the process: 648 / 420

Step 3:
420 can be fit into 648 1 times, resulting in a remainder of 228.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 420 from 648 to get 228.
Append the next digit (3) from the dividend to 228 and continue with: 2283 / 420

Let's proceed to step 4:
420 goes into 2283 5 times with a remainder of 183.
The next digit of our result is 5. 
Result so far: 15.0
Subtract 2100 from 2283 to get 183.
Take the next digit (0) from the dividend and append it to 183, then repeat: 1830 / 420

On to step 5:
The number 420 fits into 1830 4 times, leaving a remainder of 150.
Write down 4 as next digit of the result. 
Result so far: 154.0
Subtracting 1680 from 1830 leaves us with 150.
Take the next digit (2) from the dividend and append it to 150, then repeat: 1502 / 420

Advancing to step 6:
The number 420 fits into 1502 3 times, leaving a remainder of 242.
The number 3 becomes the next digit in our result. 
Result so far: 1543.0
Subtracting 1260 from 1502 leaves us with 242.
Bring next digit (8) of the dividend behind the 242 and repeat the process: 2428 / 420

Let's proceed to step 7:
420 goes into 2428 5 times with a remainder of 328.
The number 5 becomes the next digit in our result. 
Result so far: 15435.0
Deduct 2100 from 2428 and we're left with 328.
Grab the next digit (3) from the dividend, add it to 328, then carry on: 3283 / 420

Going ahead to step 8:
420 can be fit into 3283 7 times, resulting in a remainder of 343.
The next digit of our result is 7. 
Result so far: 154357.0
The remainder is 343 after subtracting 2940 from 3283.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3430, and continue the process.

Going ahead to step 9:
When dividing 3430 by 420, we get 8 with a remainder of 70.
Put 8 as the next digit of the answer. 
Result so far: 154357.8
If we take 3360 away from 3430, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 10:
420 can be fit into 700 1 times, resulting in a remainder of 280.
The next digit of our result is 1. 
Result so far: 154357.81
Deduct 420 from 700 and we're left with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Going ahead to step 11:
The number 420 fits into 2800 6 times, leaving a remainder of 280.
Put 6 as the next digit of the answer. 
Result so far: 154357.816
Deduct 2520 from 2800 and we're left with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Step 12:
420 goes into 2800 6 times with a remainder of 280.
Put 6 as the next digit of the answer. 
Result so far: 154357.8166
Subtract 2520 from 2800 to get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

After the division, we end up with 154357.8166 and a remainder of 0.0028.
