We look at the division of 862121 by 70 
We're looking to find how many times 70 goes into 862121.

Let's proceed to step 1:
70 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 70

Let's proceed to step 2:
86 divided by 70 is 1 with a remainder of 16.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 70 from 86 to get 16.
Append the next digit (2) from the dividend to 16 and continue with: 162 / 70

Let's proceed to step 3:
70 can be fit into 162 2 times, resulting in a remainder of 22.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we subtract 140 from 162, we get 22.
Grab the next digit (1) from the dividend, add it to 22, then carry on: 221 / 70

Going ahead to step 4:
When dividing 221 by 70, we get 3 with a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 123.0
If we subtract 210 from 221, we get 11.
Bring next digit (2) of the dividend behind the 11 and repeat the process: 112 / 70

Let's proceed to step 5:
When dividing 112 by 70, we get 1 with a remainder of 42.
Write down 1 as next digit of the result. 
Result so far: 1231.0
If we take 70 away from 112, we end up with 42.
Grab the next digit (1) from the dividend, add it to 42, then carry on: 421 / 70

Advancing to step 6:
421 divided by 70 is 6 with a remainder of 1.
The next digit of our result is 6. 
Result so far: 12316.0
If we take 420 away from 421, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 7:
70 can be fit into 10 0 times, resulting in a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 12316.0
If we subtract 0 from 10, we 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.

Let's proceed to step 8:
When dividing 100 by 70, we get 1 with a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 12316.01
Subtract 70 from 100 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 9:
When dividing 300 by 70, we get 4 with a remainder of 20.
The next digit of our result is 4. 
Result so far: 12316.014
If we take 280 away from 300, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 10:
The number 70 fits into 200 2 times, leaving a remainder of 60.
Write down 2 as next digit of the result. 
Result so far: 12316.0142
If we subtract 140 from 200, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 11:
70 goes into 600 8 times with a remainder of 40.
The number 8 becomes the next digit in our result. 
Result so far: 12316.01428
Deduct 560 from 600 and we're left 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.

On to step 12:
70 goes into 400 5 times with a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 12316.014285
If we subtract 350 from 400, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 13:
If we divide 500 by 70, we get 7 and a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 12316.0142857
The remainder is 10 after subtracting 490 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 14:
When dividing 100 by 70, we get 1 with a remainder of 30.
The next digit of our result is 1. 
Result so far: 12316.01428571
If we subtract 70 from 100, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

After the division, we end up with 12316.01428571 and a remainder of 3e-08.
