We're dividing 87813638 by 840 
We're looking to find how many times 840 goes into 87813638.

Let's proceed to step 1:
If we divide 8 by 840, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 840

Let's proceed to step 2:
When dividing 87 by 840, we get 0 with a remainder of 87.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 87 and we're left with 87.
Fetch the next digit (8) from the dividend, attach it to 87 and continue: 878 / 840

Step 3:
If we divide 878 by 840, we get 1 and a remainder of 38.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 840 from 878, we get 38.
Take the next digit (1) from the dividend and append it to 38, then repeat: 381 / 840

Step 4:
381 divided by 840 is 0 with a remainder of 381.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we subtract 0 from 381, we get 381.
Append the next digit (3) from the dividend to 381 and continue with: 3813 / 840

Let's proceed to step 5:
The number 840 fits into 3813 4 times, leaving a remainder of 453.
The number 4 becomes the next digit in our result. 
Result so far: 104.0
If we subtract 3360 from 3813, we get 453.
Append the next digit (6) from the dividend to 453 and continue with: 4536 / 840

Going ahead to step 6:
840 goes into 4536 5 times with a remainder of 336.
Record the quotient 5 as the next digit in the result. 
Result so far: 1045.0
If we take 4200 away from 4536, we end up with 336.
Take the next digit (3) from the dividend and append it to 336, then repeat: 3363 / 840

Going ahead to step 7:
When dividing 3363 by 840, we get 4 with a remainder of 3.
Put 4 as the next digit of the answer. 
Result so far: 10454.0
If we take 3360 away from 3363, we end up with 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 840

On to step 8:
When dividing 38 by 840, we get 0 with a remainder of 38.
Put 0 as the next digit of the answer. 
Result so far: 104540.0
Subtract 0 from 38 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 9:
The number 840 fits into 380 0 times, leaving a remainder of 380.
The number 0 becomes the next digit in our result. 
Result so far: 104540.0
The remainder is 380 after subtracting 0 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Step 10:
When dividing 3800 by 840, we get 4 with a remainder of 440.
Write down 4 as next digit of the result. 
Result so far: 104540.04
Deduct 3360 from 3800 and we're left with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Advancing to step 11:
When dividing 4400 by 840, we get 5 with a remainder of 200.
Write down 5 as next digit of the result. 
Result so far: 104540.045
Deduct 4200 from 4400 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Let's proceed to step 12:
840 can be fit into 2000 2 times, resulting in a remainder of 320.
The number 2 becomes the next digit in our result. 
Result so far: 104540.0452
Subtracting 1680 from 2000 leaves us with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Going ahead to step 13:
840 goes into 3200 3 times with a remainder of 680.
Record the quotient 3 as the next digit in the result. 
Result so far: 104540.04523
Deduct 2520 from 3200 and we're left with 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Advancing to step 14:
When dividing 6800 by 840, we get 8 with a remainder of 80.
Put 8 as the next digit of the answer. 
Result so far: 104540.045238
Subtracting 6720 from 6800 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 15:
The number 840 fits into 800 0 times, leaving a remainder of 800.
The next digit of our result is 0. 
Result so far: 104540.045238
Subtracting 0 from 800 leaves us with 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

Moving on to step 16:
8000 divided by 840 is 9 with a remainder of 440.
The number 9 becomes the next digit in our result. 
Result so far: 104540.04523809
Subtracting 7560 from 8000 leaves us with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

The quotient of the division is 104540.04523809, and the remainder is 4.4e-07.
