We're dividing 56783828 by 421 
We're looking to find how many times 421 goes into 56783828.

Going ahead to step 1:
When dividing 5 by 421, we get 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (6) from the dividend to 5 and continue with: 56 / 421

Advancing to step 2:
If we divide 56 by 421, we get 0 and a remainder of 56.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 56 leaves us with 56.
Include the next digit (7) from the dividend after 56, then repeat: 567 / 421

Going ahead to step 3:
421 can be fit into 567 1 times, resulting in a remainder of 146.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 421 from 567 leaves us with 146.
Include the next digit (8) from the dividend after 146, then repeat: 1468 / 421

Going ahead to step 4:
If we divide 1468 by 421, we get 3 and a remainder of 205.
Write down 3 as next digit of the result. 
Result so far: 13.0
The remainder is 205 after subtracting 1263 from 1468.
Take the next digit (3) from the dividend and append it to 205, then repeat: 2053 / 421

Moving on to step 5:
421 can be fit into 2053 4 times, resulting in a remainder of 369.
Use 4 as the next digit of our solution. 
Result so far: 134.0
If we take 1684 away from 2053, we end up with 369.
Bring next digit (8) of the dividend behind the 369 and repeat the process: 3698 / 421

Let's proceed to step 6:
421 goes into 3698 8 times with a remainder of 330.
Write down 8 as next digit of the result. 
Result so far: 1348.0
Deduct 3368 from 3698 and we're left with 330.
Grab the next digit (2) from the dividend, add it to 330, then carry on: 3302 / 421

Let's proceed to step 7:
421 can be fit into 3302 7 times, resulting in a remainder of 355.
Put 7 as the next digit of the answer. 
Result so far: 13487.0
Subtracting 2947 from 3302 leaves us with 355.
Grab the next digit (8) from the dividend, add it to 355, then carry on: 3558 / 421

Going ahead to step 8:
If we divide 3558 by 421, we get 8 and a remainder of 190.
Write down 8 as next digit of the result. 
Result so far: 134878.0
If we subtract 3368 from 3558, we get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Step 9:
When dividing 1900 by 421, we get 4 with a remainder of 216.
The next digit of our result is 4. 
Result so far: 134878.4
If we subtract 1684 from 1900, we get 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Step 10:
421 goes into 2160 5 times with a remainder of 55.
Use 5 as the next digit of our solution. 
Result so far: 134878.45
Subtract 2105 from 2160 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 11:
550 divided by 421 is 1 with a remainder of 129.
The number 1 becomes the next digit in our result. 
Result so far: 134878.451
If we take 421 away from 550, we end up with 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

On to step 12:
If we divide 1290 by 421, we get 3 and a remainder of 27.
Record the quotient 3 as the next digit in the result. 
Result so far: 134878.4513
Subtract 1263 from 1290 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 13:
When dividing 270 by 421, we get 0 with a remainder of 270.
The number 0 becomes the next digit in our result. 
Result so far: 134878.4513
Deduct 0 from 270 and we're left with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

On to step 14:
If we divide 2700 by 421, we get 6 and a remainder of 174.
The number 6 becomes the next digit in our result. 
Result so far: 134878.451306
The remainder is 174 after subtracting 2526 from 2700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Going ahead to step 15:
If we divide 1740 by 421, we get 4 and a remainder of 56.
Write down 4 as next digit of the result. 
Result so far: 134878.4513064
If we subtract 1684 from 1740, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 16:
421 can be fit into 560 1 times, resulting in a remainder of 139.
The number 1 becomes the next digit in our result. 
Result so far: 134878.45130641
Subtracting 421 from 560 leaves us with 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

The final outcome is 134878.45130641, with a leftover of 1.39e-07.
