We're dividing 21486377 by 845 
Our goal is to divide 21486377 by 845.

Advancing to step 1:
When dividing 2 by 845, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 845

Step 2:
The number 845 fits into 21 0 times, leaving a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Grab the next digit (4) from the dividend, add it to 21, then carry on: 214 / 845

Moving on to step 3:
If we divide 214 by 845, we get 0 and a remainder of 214.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 214 leaves us with 214.
Append the next digit (8) from the dividend to 214 and continue with: 2148 / 845

Step 4:
When dividing 2148 by 845, we get 2 with a remainder of 458.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 1690 from 2148 to get 458.
Include the next digit (6) from the dividend after 458, then repeat: 4586 / 845

Moving on to step 5:
845 goes into 4586 5 times with a remainder of 361.
Put 5 as the next digit of the answer. 
Result so far: 25.0
Deduct 4225 from 4586 and we're left with 361.
Bring next digit (3) of the dividend behind the 361 and repeat the process: 3613 / 845

Advancing to step 6:
The number 845 fits into 3613 4 times, leaving a remainder of 233.
Write down 4 as next digit of the result. 
Result so far: 254.0
Deduct 3380 from 3613 and we're left with 233.
Include the next digit (7) from the dividend after 233, then repeat: 2337 / 845

Let's proceed to step 7:
845 goes into 2337 2 times with a remainder of 647.
The number 2 becomes the next digit in our result. 
Result so far: 2542.0
Subtracting 1690 from 2337 leaves us with 647.
Grab the next digit (7) from the dividend, add it to 647, then carry on: 6477 / 845

Going ahead to step 8:
845 can be fit into 6477 7 times, resulting in a remainder of 562.
The number 7 becomes the next digit in our result. 
Result so far: 25427.0
Subtracting 5915 from 6477 leaves us with 562.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5620, and continue the process.

Step 9:
When dividing 5620 by 845, we get 6 with a remainder of 550.
Put 6 as the next digit of the answer. 
Result so far: 25427.6
If we take 5070 away from 5620, we end up with 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Advancing to step 10:
When dividing 5500 by 845, we get 6 with a remainder of 430.
Record the quotient 6 as the next digit in the result. 
Result so far: 25427.66
Deduct 5070 from 5500 and we're left with 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Our division results in 25427.66 with a remaining 0.43.
