56122803 divided by 420 
Our goal is to divide 56122803 by 420.

On to step 1:
420 goes into 5 0 times 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.
Grab the next digit (6) from the dividend, add it to 5, then carry on: 56 / 420

Going ahead to step 2:
420 can be fit into 56 0 times, resulting in a remainder of 56.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 56 and we're left with 56.
Fetch the next digit (1) from the dividend, attach it to 56 and continue: 561 / 420

Let's proceed to step 3:
If we divide 561 by 420, we get 1 and a remainder of 141.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 420 from 561 and we're left with 141.
Grab the next digit (2) from the dividend, add it to 141, then carry on: 1412 / 420

On to step 4:
When dividing 1412 by 420, we get 3 with a remainder of 152.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
The remainder is 152 after subtracting 1260 from 1412.
Bring next digit (2) of the dividend behind the 152 and repeat the process: 1522 / 420

Advancing to step 5:
When dividing 1522 by 420, we get 3 with a remainder of 262.
Record the quotient 3 as the next digit in the result. 
Result so far: 133.0
Subtract 1260 from 1522 to get 262.
Fetch the next digit (8) from the dividend, attach it to 262 and continue: 2628 / 420

Advancing to step 6:
420 can be fit into 2628 6 times, resulting in a remainder of 108.
Write down 6 as next digit of the result. 
Result so far: 1336.0
Subtracting 2520 from 2628 leaves us with 108.
Grab the next digit (0) from the dividend, add it to 108, then carry on: 1080 / 420

Moving on to step 7:
The number 420 fits into 1080 2 times, leaving a remainder of 240.
Put 2 as the next digit of the answer. 
Result so far: 13362.0
If we take 840 away from 1080, we end up with 240.
Append the next digit (3) from the dividend to 240 and continue with: 2403 / 420

Let's proceed to step 8:
2403 divided by 420 is 5 with a remainder of 303.
Use 5 as the next digit of our solution. 
Result so far: 133625.0
Subtract 2100 from 2403 to get 303.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3030, and continue the process.

Step 9:
When dividing 3030 by 420, we get 7 with a remainder of 90.
Write down 7 as next digit of the result. 
Result so far: 133625.7
If we take 2940 away from 3030, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Going ahead to step 10:
420 can be fit into 900 2 times, resulting in a remainder of 60.
Write down 2 as next digit of the result. 
Result so far: 133625.72
Subtracting 840 from 900 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 11:
420 goes into 600 1 times with a remainder of 180.
Write down 1 as next digit of the result. 
Result so far: 133625.721
Subtract 420 from 600 to get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Advancing to step 12:
The number 420 fits into 1800 4 times, leaving a remainder of 120.
The next digit of our result is 4. 
Result so far: 133625.7214
Subtract 1680 from 1800 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Let's proceed to step 13:
420 can be fit into 1200 2 times, resulting in a remainder of 360.
Write down 2 as next digit of the result. 
Result so far: 133625.72142
The remainder is 360 after subtracting 840 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Going ahead to step 14:
The number 420 fits into 3600 8 times, leaving a remainder of 240.
Use 8 as the next digit of our solution. 
Result so far: 133625.721428
Subtract 3360 from 3600 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Advancing to step 15:
When dividing 2400 by 420, we get 5 with a remainder of 300.
The next digit of our result is 5. 
Result so far: 133625.7214285
Deduct 2100 from 2400 and we're left with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Moving on to step 16:
3000 divided by 420 is 7 with a remainder of 60.
The number 7 becomes the next digit in our result. 
Result so far: 133625.72142857
If we subtract 2940 from 3000, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Our division results in 133625.72142857 with a remaining 6e-08.
