We look at the division of 68578702 by 840 
Our goal is to divide 68578702 by 840.

Advancing to step 1:
When dividing 6 by 840, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 840

Advancing to step 2:
840 can be fit into 68 0 times, resulting in a remainder of 68.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 68 and we're left with 68.
Fetch the next digit (5) from the dividend, attach it to 68 and continue: 685 / 840

Moving on to step 3:
840 goes into 685 0 times with a remainder of 685.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 685, we end up with 685.
Include the next digit (7) from the dividend after 685, then repeat: 6857 / 840

Let's proceed to step 4:
840 can be fit into 6857 8 times, resulting in a remainder of 137.
Write down 8 as next digit of the result. 
Result so far: 8.0
Deduct 6720 from 6857 and we're left with 137.
Bring next digit (8) of the dividend behind the 137 and repeat the process: 1378 / 840

Advancing to step 5:
If we divide 1378 by 840, we get 1 and a remainder of 538.
The next digit of our result is 1. 
Result so far: 81.0
The remainder is 538 after subtracting 840 from 1378.
Include the next digit (7) from the dividend after 538, then repeat: 5387 / 840

On to step 6:
The number 840 fits into 5387 6 times, leaving a remainder of 347.
The next digit of our result is 6. 
Result so far: 816.0
If we subtract 5040 from 5387, we get 347.
Take the next digit (0) from the dividend and append it to 347, then repeat: 3470 / 840

Moving on to step 7:
840 can be fit into 3470 4 times, resulting in a remainder of 110.
Write down 4 as next digit of the result. 
Result so far: 8164.0
Subtract 3360 from 3470 to get 110.
Include the next digit (2) from the dividend after 110, then repeat: 1102 / 840

Moving on to step 8:
840 can be fit into 1102 1 times, resulting in a remainder of 262.
The next digit of our result is 1. 
Result so far: 81641.0
Subtracting 840 from 1102 leaves us with 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

On to step 9:
The number 840 fits into 2620 3 times, leaving a remainder of 100.
Use 3 as the next digit of our solution. 
Result so far: 81641.3
Subtract 2520 from 2620 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 10:
The number 840 fits into 1000 1 times, leaving a remainder of 160.
Record the quotient 1 as the next digit in the result. 
Result so far: 81641.31
If we subtract 840 from 1000, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 11:
If we divide 1600 by 840, we get 1 and a remainder of 760.
The number 1 becomes the next digit in our result. 
Result so far: 81641.311
Deduct 840 from 1600 and we're left 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.

Our division results in 81641.311 with a remaining 0.076.
