Let's divide 45641085 by 840
Our goal is to divide 45641085 by 840.

Let's proceed to step 1:
840 goes into 4 0 times with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 840

Moving on to step 2:
840 can be fit into 45 0 times, resulting in a remainder of 45.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 45 leaves us with 45.
Append the next digit (6) from the dividend to 45 and continue with: 456 / 840

On to step 3:
When dividing 456 by 840, we get 0 with a remainder of 456.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 456, we end up with 456.
Fetch the next digit (4) from the dividend, attach it to 456 and continue: 4564 / 840

On to step 4:
4564 divided by 840 is 5 with a remainder of 364.
Put 5 as the next digit of the answer. 
Result so far: 5.0
The remainder is 364 after subtracting 4200 from 4564.
Fetch the next digit (1) from the dividend, attach it to 364 and continue: 3641 / 840

Moving on to step 5:
840 can be fit into 3641 4 times, resulting in a remainder of 281.
Put 4 as the next digit of the answer. 
Result so far: 54.0
The remainder is 281 after subtracting 3360 from 3641.
Fetch the next digit (0) from the dividend, attach it to 281 and continue: 2810 / 840

Step 6:
When dividing 2810 by 840, we get 3 with a remainder of 290.
The next digit of our result is 3. 
Result so far: 543.0
The remainder is 290 after subtracting 2520 from 2810.
Fetch the next digit (8) from the dividend, attach it to 290 and continue: 2908 / 840

On to step 7:
When dividing 2908 by 840, we get 3 with a remainder of 388.
The number 3 becomes the next digit in our result. 
Result so far: 5433.0
If we subtract 2520 from 2908, we get 388.
Take the next digit (5) from the dividend and append it to 388, then repeat: 3885 / 840

Going ahead to step 8:
When dividing 3885 by 840, we get 4 with a remainder of 525.
Put 4 as the next digit of the answer. 
Result so far: 54334.0
Subtract 3360 from 3885 to get 525.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5250, and continue the process.

Going ahead to step 9:
The number 840 fits into 5250 6 times, leaving a remainder of 210.
Use 6 as the next digit of our solution. 
Result so far: 54334.6
If we subtract 5040 from 5250, we get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Step 10:
840 can be fit into 2100 2 times, resulting in a remainder of 420.
Record the quotient 2 as the next digit in the result. 
Result so far: 54334.62
Subtracting 1680 from 2100 leaves us with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Let's proceed to step 11:
The number 840 fits into 4200 5 times, leaving a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 54334.625
The remainder is 0 after subtracting 4200 from 4200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 12:
0 divided by 840 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 54334.625
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 13:
840 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 54334.625
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 54334.625 with a remainder of 0.0.
