We're dividing 61871863 by 840 
Our goal is to divide 61871863 by 840.

Step 1:
If we divide 6 by 840, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (1) from the dividend and append it to 6, then repeat: 61 / 840

Step 2:
The number 840 fits into 61 0 times, leaving a remainder of 61.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 61 after subtracting 0 from 61.
Take the next digit (8) from the dividend and append it to 61, then repeat: 618 / 840

Moving on to step 3:
840 goes into 618 0 times with a remainder of 618.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 618 to get 618.
Append the next digit (7) from the dividend to 618 and continue with: 6187 / 840

On to step 4:
840 can be fit into 6187 7 times, resulting in a remainder of 307.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we subtract 5880 from 6187, we get 307.
Fetch the next digit (1) from the dividend, attach it to 307 and continue: 3071 / 840

Let's proceed to step 5:
When dividing 3071 by 840, we get 3 with a remainder of 551.
The number 3 becomes the next digit in our result. 
Result so far: 73.0
Subtracting 2520 from 3071 leaves us with 551.
Grab the next digit (8) from the dividend, add it to 551, then carry on: 5518 / 840

On to step 6:
If we divide 5518 by 840, we get 6 and a remainder of 478.
Record the quotient 6 as the next digit in the result. 
Result so far: 736.0
Deduct 5040 from 5518 and we're left with 478.
Append the next digit (6) from the dividend to 478 and continue with: 4786 / 840

Advancing to step 7:
4786 divided by 840 is 5 with a remainder of 586.
The next digit of our result is 5. 
Result so far: 7365.0
Deduct 4200 from 4786 and we're left with 586.
Append the next digit (3) from the dividend to 586 and continue with: 5863 / 840

On to step 8:
840 can be fit into 5863 6 times, resulting in a remainder of 823.
Put 6 as the next digit of the answer. 
Result so far: 73656.0
If we subtract 5040 from 5863, we get 823.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8230, and continue the process.

Moving on to step 9:
If we divide 8230 by 840, we get 9 and a remainder of 670.
Put 9 as the next digit of the answer. 
Result so far: 73656.9
If we subtract 7560 from 8230, we get 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6700, and continue the process.

Step 10:
If we divide 6700 by 840, we get 7 and a remainder of 820.
Write down 7 as next digit of the result. 
Result so far: 73656.97
Subtracting 5880 from 6700 leaves us with 820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8200, and continue the process.

Moving on to step 11:
8200 divided by 840 is 9 with a remainder of 640.
The number 9 becomes the next digit in our result. 
Result so far: 73656.979
Deduct 7560 from 8200 and we're left with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

On to step 12:
The number 840 fits into 6400 7 times, leaving a remainder of 520.
Write down 7 as next digit of the result. 
Result so far: 73656.9797
If we subtract 5880 from 6400, we get 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Advancing to step 13:
The number 840 fits into 5200 6 times, leaving a remainder of 160.
The number 6 becomes the next digit in our result. 
Result so far: 73656.97976
If we take 5040 away from 5200, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 14:
1600 divided by 840 is 1 with a remainder of 760.
Write down 1 as next digit of the result. 
Result so far: 73656.979761
If we take 840 away from 1600, we end up with 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

Advancing to step 15:
840 goes into 7600 9 times with a remainder of 40.
Write down 9 as next digit of the result. 
Result so far: 73656.9797619
Subtracting 7560 from 7600 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 16:
If we divide 400 by 840, we get 0 and a remainder of 400.
The next digit of our result is 0. 
Result so far: 73656.9797619
Deduct 0 from 400 and we're left with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

After the division, we end up with 73656.9797619 and a remainder of 4e-07.
