We divide 21846423 by 451
We want to divide 21846423 by 451.

On to step 1:
451 can be fit into 2 0 times, resulting in a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 451

Going ahead to step 2:
If we divide 21 by 451, we get 0 and a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Fetch the next digit (8) from the dividend, attach it to 21 and continue: 218 / 451

Moving on to step 3:
218 divided by 451 is 0 with a remainder of 218.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 218, we get 218.
Bring next digit (4) of the dividend behind the 218 and repeat the process: 2184 / 451

Going ahead to step 4:
The number 451 fits into 2184 4 times, leaving a remainder of 380.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 1804 from 2184 and we're left with 380.
Append the next digit (6) from the dividend to 380 and continue with: 3806 / 451

On to step 5:
When dividing 3806 by 451, we get 8 with a remainder of 198.
Use 8 as the next digit of our solution. 
Result so far: 48.0
Subtracting 3608 from 3806 leaves us with 198.
Include the next digit (4) from the dividend after 198, then repeat: 1984 / 451

Moving on to step 6:
1984 divided by 451 is 4 with a remainder of 180.
Put 4 as the next digit of the answer. 
Result so far: 484.0
Deduct 1804 from 1984 and we're left with 180.
Grab the next digit (2) from the dividend, add it to 180, then carry on: 1802 / 451

Moving on to step 7:
451 goes into 1802 3 times with a remainder of 449.
Record the quotient 3 as the next digit in the result. 
Result so far: 4843.0
If we subtract 1353 from 1802, we get 449.
Append the next digit (3) from the dividend to 449 and continue with: 4493 / 451

Going ahead to step 8:
If we divide 4493 by 451, we get 9 and a remainder of 434.
Record the quotient 9 as the next digit in the result. 
Result so far: 48439.0
If we subtract 4059 from 4493, we get 434.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4340, and continue the process.

On to step 9:
The number 451 fits into 4340 9 times, leaving a remainder of 281.
Write down 9 as next digit of the result. 
Result so far: 48439.9
Deduct 4059 from 4340 and we're left with 281.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2810, and continue the process.

Moving on to step 10:
When dividing 2810 by 451, we get 6 with a remainder of 104.
Record the quotient 6 as the next digit in the result. 
Result so far: 48439.96
Deduct 2706 from 2810 and we're left with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

On to step 11:
1040 divided by 451 is 2 with a remainder of 138.
The number 2 becomes the next digit in our result. 
Result so far: 48439.962
Subtract 902 from 1040 to get 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Let's proceed to step 12:
The number 451 fits into 1380 3 times, leaving a remainder of 27.
Write down 3 as next digit of the result. 
Result so far: 48439.9623
Deduct 1353 from 1380 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 13:
451 can be fit into 270 0 times, resulting in a remainder of 270.
The next digit of our result is 0. 
Result so far: 48439.9623
The remainder is 270 after subtracting 0 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Moving on to step 14:
451 goes into 2700 5 times with a remainder of 445.
Record the quotient 5 as the next digit in the result. 
Result so far: 48439.962305
If we take 2255 away from 2700, we end up with 445.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

Going ahead to step 15:
The number 451 fits into 4450 9 times, leaving a remainder of 391.
Put 9 as the next digit of the answer. 
Result so far: 48439.9623059
If we subtract 4059 from 4450, we get 391.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3910, and continue the process.

Advancing to step 16:
The number 451 fits into 3910 8 times, leaving a remainder of 302.
The next digit of our result is 8. 
Result so far: 48439.96230598
Subtracting 3608 from 3910 leaves us with 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

In conclusion, the division gives 48439.96230598 with a balance of 3.02e-07.
