We look at the division of 7734289 by 840 
Let's see how many times 840 fits into 7734289.

Moving on to step 1:
7 divided by 840 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 840

Let's proceed to step 2:
When dividing 77 by 840, we get 0 with a remainder of 77.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 77 and we're left with 77.
Take the next digit (3) from the dividend and append it to 77, then repeat: 773 / 840

Let's proceed to step 3:
773 divided by 840 is 0 with a remainder of 773.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 773 and we're left with 773.
Bring next digit (4) of the dividend behind the 773 and repeat the process: 7734 / 840

Step 4:
840 goes into 7734 9 times with a remainder of 174.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Deduct 7560 from 7734 and we're left with 174.
Bring next digit (2) of the dividend behind the 174 and repeat the process: 1742 / 840

Going ahead to step 5:
If we divide 1742 by 840, we get 2 and a remainder of 62.
Record the quotient 2 as the next digit in the result. 
Result so far: 92.0
If we subtract 1680 from 1742, we get 62.
Include the next digit (8) from the dividend after 62, then repeat: 628 / 840

Step 6:
If we divide 628 by 840, we get 0 and a remainder of 628.
Write down 0 as next digit of the result. 
Result so far: 920.0
Subtracting 0 from 628 leaves us with 628.
Fetch the next digit (9) from the dividend, attach it to 628 and continue: 6289 / 840

On to step 7:
If we divide 6289 by 840, we get 7 and a remainder of 409.
The next digit of our result is 7. 
Result so far: 9207.0
Subtract 5880 from 6289 to get 409.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4090, and continue the process.

On to step 8:
840 can be fit into 4090 4 times, resulting in a remainder of 730.
The next digit of our result is 4. 
Result so far: 9207.4
Subtract 3360 from 4090 to get 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7300, and continue the process.

Let's proceed to step 9:
The number 840 fits into 7300 8 times, leaving a remainder of 580.
Record the quotient 8 as the next digit in the result. 
Result so far: 9207.48
Deduct 6720 from 7300 and we're left with 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Advancing to step 10:
The number 840 fits into 5800 6 times, leaving a remainder of 760.
The number 6 becomes the next digit in our result. 
Result so far: 9207.486
If we take 5040 away from 5800, 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.

Let's proceed to step 11:
When dividing 7600 by 840, we get 9 with a remainder of 40.
Put 9 as the next digit of the answer. 
Result so far: 9207.4869
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 12:
When dividing 400 by 840, we get 0 with a remainder of 400.
Put 0 as the next digit of the answer. 
Result so far: 9207.4869
The remainder is 400 after subtracting 0 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Advancing to step 13:
840 goes into 4000 4 times with a remainder of 640.
Use 4 as the next digit of our solution. 
Result so far: 9207.486904
Deduct 3360 from 4000 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.

Advancing to step 14:
840 can be fit into 6400 7 times, resulting in a remainder of 520.
The next digit of our result is 7. 
Result so far: 9207.4869047
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.

Step 15:
840 can be fit into 5200 6 times, resulting in a remainder of 160.
Record the quotient 6 as the next digit in the result. 
Result so far: 9207.48690476
Subtracting 5040 from 5200 leaves us 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.

In conclusion, the division gives 9207.48690476 with a balance of 1.6e-07.
