15542271 divided by 420 
Our goal is to divide 15542271 by 420.

On to step 1:
420 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 420

Moving on to step 2:
If we divide 15 by 420, we get 0 and a remainder of 15.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 15 leaves us with 15.
Fetch the next digit (5) from the dividend, attach it to 15 and continue: 155 / 420

Going ahead to step 3:
420 goes into 155 0 times with a remainder of 155.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 155 to get 155.
Include the next digit (4) from the dividend after 155, then repeat: 1554 / 420

Moving on to step 4:
If we divide 1554 by 420, we get 3 and a remainder of 294.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 1260 from 1554 to get 294.
Take the next digit (2) from the dividend and append it to 294, then repeat: 2942 / 420

Step 5:
If we divide 2942 by 420, we get 7 and a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 37.0
If we subtract 2940 from 2942, we get 2.
Grab the next digit (2) from the dividend, add it to 2, then carry on: 22 / 420

Step 6:
The number 420 fits into 22 0 times, leaving a remainder of 22.
Record the quotient 0 as the next digit in the result. 
Result so far: 370.0
Subtract 0 from 22 to get 22.
Bring next digit (7) of the dividend behind the 22 and repeat the process: 227 / 420

On to step 7:
If we divide 227 by 420, we get 0 and a remainder of 227.
The number 0 becomes the next digit in our result. 
Result so far: 3700.0
Subtracting 0 from 227 leaves us with 227.
Take the next digit (1) from the dividend and append it to 227, then repeat: 2271 / 420

On to step 8:
2271 divided by 420 is 5 with a remainder of 171.
Write down 5 as next digit of the result. 
Result so far: 37005.0
The remainder is 171 after subtracting 2100 from 2271.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

On to step 9:
420 can be fit into 1710 4 times, resulting in a remainder of 30.
Record the quotient 4 as the next digit in the result. 
Result so far: 37005.4
If we take 1680 away from 1710, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 10:
When dividing 300 by 420, we get 0 with a remainder of 300.
The next digit of our result is 0. 
Result so far: 37005.4
Subtracting 0 from 300 leaves us 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.

On to step 11:
420 can be fit into 3000 7 times, resulting in a remainder of 60.
Record the quotient 7 as the next digit in the result. 
Result so far: 37005.407
The remainder is 60 after subtracting 2940 from 3000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 12:
If we divide 600 by 420, we get 1 and a remainder of 180.
Write down 1 as next digit of the result. 
Result so far: 37005.4071
Subtracting 420 from 600 leaves us 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 13:
When dividing 1800 by 420, we get 4 with a remainder of 120.
Use 4 as the next digit of our solution. 
Result so far: 37005.40714
Deduct 1680 from 1800 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Moving on to step 14:
If we divide 1200 by 420, we get 2 and a remainder of 360.
Use 2 as the next digit of our solution. 
Result so far: 37005.407142
Subtract 840 from 1200 to get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Advancing to step 15:
The number 420 fits into 3600 8 times, leaving a remainder of 240.
The next digit of our result is 8. 
Result so far: 37005.4071428
The remainder is 240 after subtracting 3360 from 3600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Step 16:
When dividing 2400 by 420, we get 5 with a remainder of 300.
Put 5 as the next digit of the answer. 
Result so far: 37005.40714285
Subtracting 2100 from 2400 leaves us 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.

In conclusion, the division gives 37005.40714285 with a balance of 3e-07.
