42352454 divided by 861 
Let's see how many times 861 fits into 42352454.

Step 1:
When dividing 4 by 861, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 861

Advancing to step 2:
If we divide 42 by 861, we get 0 and a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 42 after subtracting 0 from 42.
Bring next digit (3) of the dividend behind the 42 and repeat the process: 423 / 861

Step 3:
861 can be fit into 423 0 times, resulting in a remainder of 423.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 423 after subtracting 0 from 423.
Fetch the next digit (5) from the dividend, attach it to 423 and continue: 4235 / 861

Going ahead to step 4:
If we divide 4235 by 861, we get 4 and a remainder of 791.
The next digit of our result is 4. 
Result so far: 4.0
If we subtract 3444 from 4235, we get 791.
Take the next digit (2) from the dividend and append it to 791, then repeat: 7912 / 861

Advancing to step 5:
861 can be fit into 7912 9 times, resulting in a remainder of 163.
Write down 9 as next digit of the result. 
Result so far: 49.0
Subtract 7749 from 7912 to get 163.
Bring next digit (4) of the dividend behind the 163 and repeat the process: 1634 / 861

Let's proceed to step 6:
If we divide 1634 by 861, we get 1 and a remainder of 773.
Put 1 as the next digit of the answer. 
Result so far: 491.0
If we subtract 861 from 1634, we get 773.
Include the next digit (5) from the dividend after 773, then repeat: 7735 / 861

Let's proceed to step 7:
When dividing 7735 by 861, we get 8 with a remainder of 847.
The number 8 becomes the next digit in our result. 
Result so far: 4918.0
Subtracting 6888 from 7735 leaves us with 847.
Include the next digit (4) from the dividend after 847, then repeat: 8474 / 861

On to step 8:
The number 861 fits into 8474 9 times, leaving a remainder of 725.
Write down 9 as next digit of the result. 
Result so far: 49189.0
Deduct 7749 from 8474 and we're left with 725.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7250, and continue the process.

On to step 9:
If we divide 7250 by 861, we get 8 and a remainder of 362.
The next digit of our result is 8. 
Result so far: 49189.8
The remainder is 362 after subtracting 6888 from 7250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

Step 10:
When dividing 3620 by 861, we get 4 with a remainder of 176.
Write down 4 as next digit of the result. 
Result so far: 49189.84
The remainder is 176 after subtracting 3444 from 3620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

On to step 11:
If we divide 1760 by 861, we get 2 and a remainder of 38.
Write down 2 as next digit of the result. 
Result so far: 49189.842
Subtract 1722 from 1760 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 12:
861 can be fit into 380 0 times, resulting in a remainder of 380.
The number 0 becomes the next digit in our result. 
Result so far: 49189.842
Deduct 0 from 380 and we're left with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Moving on to step 13:
861 goes into 3800 4 times with a remainder of 356.
The number 4 becomes the next digit in our result. 
Result so far: 49189.84204
If we subtract 3444 from 3800, we get 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Step 14:
861 can be fit into 3560 4 times, resulting in a remainder of 116.
Use 4 as the next digit of our solution. 
Result so far: 49189.842044
The remainder is 116 after subtracting 3444 from 3560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

After the division, we end up with 49189.842044 and a remainder of 1.16e-05.
