We divide 45221481 by 420
Our goal is to divide 45221481 by 420.

On to step 1:
The number 420 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 420

Going ahead to step 2:
When dividing 45 by 420, we get 0 with a remainder of 45.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 45, we end up with 45.
Include the next digit (2) from the dividend after 45, then repeat: 452 / 420

Let's proceed to step 3:
420 can be fit into 452 1 times, resulting in a remainder of 32.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 420 from 452 and we're left with 32.
Include the next digit (2) from the dividend after 32, then repeat: 322 / 420

Let's proceed to step 4:
322 divided by 420 is 0 with a remainder of 322.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Deduct 0 from 322 and we're left with 322.
Take the next digit (1) from the dividend and append it to 322, then repeat: 3221 / 420

Moving on to step 5:
When dividing 3221 by 420, we get 7 with a remainder of 281.
Write down 7 as next digit of the result. 
Result so far: 107.0
Deduct 2940 from 3221 and we're left with 281.
Append the next digit (4) from the dividend to 281 and continue with: 2814 / 420

Let's proceed to step 6:
The number 420 fits into 2814 6 times, leaving a remainder of 294.
The next digit of our result is 6. 
Result so far: 1076.0
Subtract 2520 from 2814 to get 294.
Take the next digit (8) from the dividend and append it to 294, then repeat: 2948 / 420

Let's proceed to step 7:
When dividing 2948 by 420, we get 7 with a remainder of 8.
The next digit of our result is 7. 
Result so far: 10767.0
Subtract 2940 from 2948 to get 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 420

On to step 8:
If we divide 81 by 420, we get 0 and a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 107670.0
If we take 0 away from 81, we end up with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Going ahead to step 9:
When dividing 810 by 420, we get 1 with a remainder of 390.
The next digit of our result is 1. 
Result so far: 107670.1
Deduct 420 from 810 and we're left with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Step 10:
When dividing 3900 by 420, we get 9 with a remainder of 120.
Write down 9 as next digit of the result. 
Result so far: 107670.19
Subtract 3780 from 3900 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.

On to step 11:
The number 420 fits into 1200 2 times, leaving a remainder of 360.
Put 2 as the next digit of the answer. 
Result so far: 107670.192
If we take 840 away from 1200, we end up with 360.
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 12:
3600 divided by 420 is 8 with a remainder of 240.
The next digit of our result is 8. 
Result so far: 107670.1928
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.

Let's proceed to step 13:
When dividing 2400 by 420, we get 5 with a remainder of 300.
The next digit of our result is 5. 
Result so far: 107670.19285
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 14:
420 goes into 3000 7 times with a remainder of 60.
Write down 7 as next digit of the result. 
Result so far: 107670.192857
Deduct 2940 from 3000 and we're left 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.

Going ahead to step 15:
When dividing 600 by 420, we get 1 with a remainder of 180.
Put 1 as the next digit of the answer. 
Result so far: 107670.1928571
If we take 420 away from 600, we end up with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Going ahead to step 16:
420 can be fit into 1800 4 times, resulting in a remainder of 120.
Write down 4 as next digit of the result. 
Result so far: 107670.19285714
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.

In conclusion, the division gives 107670.19285714 with a balance of 1.2e-07.
