70359402 ÷ 840 
We want to figure out the number of times 70359402 can be divided by 840.

Advancing to step 1:
When dividing 7 by 840, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 840

Moving on to step 2:
The number 840 fits into 70 0 times, leaving a remainder of 70.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 70 leaves us with 70.
Append the next digit (3) from the dividend to 70 and continue with: 703 / 840

Going ahead to step 3:
The number 840 fits into 703 0 times, leaving a remainder of 703.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 703, we get 703.
Append the next digit (5) from the dividend to 703 and continue with: 7035 / 840

On to step 4:
If we divide 7035 by 840, we get 8 and a remainder of 315.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we subtract 6720 from 7035, we get 315.
Grab the next digit (9) from the dividend, add it to 315, then carry on: 3159 / 840

Let's proceed to step 5:
If we divide 3159 by 840, we get 3 and a remainder of 639.
The next digit of our result is 3. 
Result so far: 83.0
If we take 2520 away from 3159, we end up with 639.
Include the next digit (4) from the dividend after 639, then repeat: 6394 / 840

Step 6:
6394 divided by 840 is 7 with a remainder of 514.
Use 7 as the next digit of our solution. 
Result so far: 837.0
Subtract 5880 from 6394 to get 514.
Fetch the next digit (0) from the dividend, attach it to 514 and continue: 5140 / 840

Let's proceed to step 7:
If we divide 5140 by 840, we get 6 and a remainder of 100.
Write down 6 as next digit of the result. 
Result so far: 8376.0
If we take 5040 away from 5140, we end up with 100.
Include the next digit (2) from the dividend after 100, then repeat: 1002 / 840

On to step 8:
The number 840 fits into 1002 1 times, leaving a remainder of 162.
The number 1 becomes the next digit in our result. 
Result so far: 83761.0
The remainder is 162 after subtracting 840 from 1002.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Let's proceed to step 9:
840 goes into 1620 1 times with a remainder of 780.
Use 1 as the next digit of our solution. 
Result so far: 83761.1
Deduct 840 from 1620 and we're left with 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7800, and continue the process.

Going ahead to step 10:
840 can be fit into 7800 9 times, resulting in a remainder of 240.
Put 9 as the next digit of the answer. 
Result so far: 83761.19
If we subtract 7560 from 7800, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Step 11:
If we divide 2400 by 840, we get 2 and a remainder of 720.
Use 2 as the next digit of our solution. 
Result so far: 83761.192
Subtracting 1680 from 2400 leaves us with 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Advancing to step 12:
The number 840 fits into 7200 8 times, leaving a remainder of 480.
Record the quotient 8 as the next digit in the result. 
Result so far: 83761.1928
If we subtract 6720 from 7200, we get 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Let's proceed to step 13:
The number 840 fits into 4800 5 times, leaving a remainder of 600.
Put 5 as the next digit of the answer. 
Result so far: 83761.19285
Deduct 4200 from 4800 and we're left with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

On to step 14:
6000 divided by 840 is 7 with a remainder of 120.
The next digit of our result is 7. 
Result so far: 83761.192857
Deduct 5880 from 6000 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Step 15:
If we divide 1200 by 840, we get 1 and a remainder of 360.
The number 1 becomes the next digit in our result. 
Result so far: 83761.1928571
If we take 840 away from 1200, we end up with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Going ahead to step 16:
When dividing 3600 by 840, we get 4 with a remainder of 240.
Use 4 as the next digit of our solution. 
Result so far: 83761.19285714
Subtract 3360 from 3600 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

In conclusion, the division gives 83761.19285714 with a balance of 2.4e-07.
