84820394 ÷ 70 
We want to divide 84820394 by 70.

Moving on to step 1:
70 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 70

Advancing to step 2:
70 goes into 84 1 times with a remainder of 14.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 70 from 84 and we're left with 14.
Fetch the next digit (8) from the dividend, attach it to 14 and continue: 148 / 70

Advancing to step 3:
If we divide 148 by 70, we get 2 and a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Deduct 140 from 148 and we're left with 8.
Grab the next digit (2) from the dividend, add it to 8, then carry on: 82 / 70

Advancing to step 4:
If we divide 82 by 70, we get 1 and a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 121.0
Subtracting 70 from 82 leaves us with 12.
Bring next digit (0) of the dividend behind the 12 and repeat the process: 120 / 70

Step 5:
120 divided by 70 is 1 with a remainder of 50.
Use 1 as the next digit of our solution. 
Result so far: 1211.0
The remainder is 50 after subtracting 70 from 120.
Bring next digit (3) of the dividend behind the 50 and repeat the process: 503 / 70

Advancing to step 6:
When dividing 503 by 70, we get 7 with a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 12117.0
Deduct 490 from 503 and we're left with 13.
Append the next digit (9) from the dividend to 13 and continue with: 139 / 70

Step 7:
139 divided by 70 is 1 with a remainder of 69.
The number 1 becomes the next digit in our result. 
Result so far: 121171.0
The remainder is 69 after subtracting 70 from 139.
Include the next digit (4) from the dividend after 69, then repeat: 694 / 70

Let's proceed to step 8:
70 goes into 694 9 times with a remainder of 64.
The number 9 becomes the next digit in our result. 
Result so far: 1211719.0
Subtract 630 from 694 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 9:
640 divided by 70 is 9 with a remainder of 10.
The number 9 becomes the next digit in our result. 
Result so far: 1211719.9
Subtract 630 from 640 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 10:
When dividing 100 by 70, we get 1 with a remainder of 30.
The number 1 becomes the next digit in our result. 
Result so far: 1211719.91
If we take 70 away from 100, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 11:
300 divided by 70 is 4 with a remainder of 20.
The number 4 becomes the next digit in our result. 
Result so far: 1211719.914
Subtract 280 from 300 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 12:
70 goes into 200 2 times with a remainder of 60.
Put 2 as the next digit of the answer. 
Result so far: 1211719.9142
The remainder is 60 after subtracting 140 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 13:
If we divide 600 by 70, we get 8 and a remainder of 40.
Put 8 as the next digit of the answer. 
Result so far: 1211719.91428
Subtract 560 from 600 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 14:
70 goes into 400 5 times with a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 1211719.914285
The remainder is 50 after subtracting 350 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 15:
500 divided by 70 is 7 with a remainder of 10.
The next digit of our result is 7. 
Result so far: 1211719.9142857
Subtracting 490 from 500 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 16:
If we divide 100 by 70, we get 1 and a remainder of 30.
Put 1 as the next digit of the answer. 
Result so far: 1211719.91428571
If we take 70 away from 100, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The final result is 1211719.91428571 with a remainder of 3e-08.
