86193277 divided by 840 
We want to divide 86193277 by 840.

Moving on to step 1:
8 divided by 840 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 840

Step 2:
86 divided by 840 is 0 with a remainder of 86.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 86 to get 86.
Bring next digit (1) of the dividend behind the 86 and repeat the process: 861 / 840

On to step 3:
When dividing 861 by 840, we get 1 with a remainder of 21.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 840 away from 861, we end up with 21.
Take the next digit (9) from the dividend and append it to 21, then repeat: 219 / 840

Step 4:
840 can be fit into 219 0 times, resulting in a remainder of 219.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we take 0 away from 219, we end up with 219.
Fetch the next digit (3) from the dividend, attach it to 219 and continue: 2193 / 840

Let's proceed to step 5:
840 goes into 2193 2 times with a remainder of 513.
Record the quotient 2 as the next digit in the result. 
Result so far: 102.0
Subtracting 1680 from 2193 leaves us with 513.
Take the next digit (2) from the dividend and append it to 513, then repeat: 5132 / 840

Moving on to step 6:
When dividing 5132 by 840, we get 6 with a remainder of 92.
Put 6 as the next digit of the answer. 
Result so far: 1026.0
If we subtract 5040 from 5132, we get 92.
Take the next digit (7) from the dividend and append it to 92, then repeat: 927 / 840

Going ahead to step 7:
840 can be fit into 927 1 times, resulting in a remainder of 87.
Write down 1 as next digit of the result. 
Result so far: 10261.0
If we subtract 840 from 927, we get 87.
Include the next digit (7) from the dividend after 87, then repeat: 877 / 840

Advancing to step 8:
840 can be fit into 877 1 times, resulting in a remainder of 37.
The next digit of our result is 1. 
Result so far: 102611.0
Subtract 840 from 877 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 9:
370 divided by 840 is 0 with a remainder of 370.
The next digit of our result is 0. 
Result so far: 102611.0
Subtract 0 from 370 to get 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Going ahead to step 10:
The number 840 fits into 3700 4 times, leaving a remainder of 340.
Put 4 as the next digit of the answer. 
Result so far: 102611.04
The remainder is 340 after subtracting 3360 from 3700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Advancing to step 11:
When dividing 3400 by 840, we get 4 with a remainder of 40.
Record the quotient 4 as the next digit in the result. 
Result so far: 102611.044
The remainder is 40 after subtracting 3360 from 3400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Our division results in 102611.044 with a remaining 0.004.
