We look at the division of 420621 by 56 
We're looking to find how many times 56 goes into 420621.

Moving on to step 1:
4 divided by 56 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 56

Step 2:
If we divide 42 by 56, we get 0 and a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 42, we end up with 42.
Take the next digit (0) from the dividend and append it to 42, then repeat: 420 / 56

Moving on to step 3:
56 can be fit into 420 7 times, resulting in a remainder of 28.
The next digit of our result is 7. 
Result so far: 7.0
Subtracting 392 from 420 leaves us with 28.
Fetch the next digit (6) from the dividend, attach it to 28 and continue: 286 / 56

Advancing to step 4:
56 can be fit into 286 5 times, resulting in a remainder of 6.
Put 5 as the next digit of the answer. 
Result so far: 75.0
Subtract 280 from 286 to get 6.
Bring next digit (2) of the dividend behind the 6 and repeat the process: 62 / 56

Let's proceed to step 5:
56 can be fit into 62 1 times, resulting in a remainder of 6.
The next digit of our result is 1. 
Result so far: 751.0
The remainder is 6 after subtracting 56 from 62.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 56

Let's proceed to step 6:
If we divide 61 by 56, we get 1 and a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 7511.0
If we take 56 away from 61, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 7:
The number 56 fits into 50 0 times, leaving a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 7511.0
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 8:
56 can be fit into 500 8 times, resulting in a remainder of 52.
Write down 8 as next digit of the result. 
Result so far: 7511.08
Deduct 448 from 500 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 9:
When dividing 520 by 56, we get 9 with a remainder of 16.
The next digit of our result is 9. 
Result so far: 7511.089
The remainder is 16 after subtracting 504 from 520.
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 10:
If we divide 160 by 56, we get 2 and a remainder of 48.
The next digit of our result is 2. 
Result so far: 7511.0892
Subtracting 112 from 160 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 11:
56 can be fit into 480 8 times, resulting in a remainder of 32.
Record the quotient 8 as the next digit in the result. 
Result so far: 7511.08928
Deduct 448 from 480 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 12:
The number 56 fits into 320 5 times, leaving a remainder of 40.
Put 5 as the next digit of the answer. 
Result so far: 7511.089285
If we take 280 away from 320, we end up 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.

Going ahead to step 13:
56 goes into 400 7 times with a remainder of 8.
Record the quotient 7 as the next digit in the result. 
Result so far: 7511.0892857
If we take 392 away from 400, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 14:
The number 56 fits into 80 1 times, leaving a remainder of 24.
The next digit of our result is 1. 
Result so far: 7511.08928571
Deduct 56 from 80 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

After the division, we end up with 7511.08928571 and a remainder of 2.4e-08.
