We look at the division of 155391 by 70 
Let's see how many times 70 fits into 155391.

Advancing to step 1:
When dividing 1 by 70, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 70

Moving on to step 2:
15 divided by 70 is 0 with a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Grab the next digit (5) from the dividend, add it to 15, then carry on: 155 / 70

On to step 3:
If we divide 155 by 70, we get 2 and a remainder of 15.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 140 from 155 and we're left with 15.
Append the next digit (3) from the dividend to 15 and continue with: 153 / 70

Let's proceed to step 4:
When dividing 153 by 70, we get 2 with a remainder of 13.
Put 2 as the next digit of the answer. 
Result so far: 22.0
The remainder is 13 after subtracting 140 from 153.
Fetch the next digit (9) from the dividend, attach it to 13 and continue: 139 / 70

Let's proceed to step 5:
70 goes into 139 1 times with a remainder of 69.
Record the quotient 1 as the next digit in the result. 
Result so far: 221.0
The remainder is 69 after subtracting 70 from 139.
Grab the next digit (1) from the dividend, add it to 69, then carry on: 691 / 70

Advancing to step 6:
691 divided by 70 is 9 with a remainder of 61.
The number 9 becomes the next digit in our result. 
Result so far: 2219.0
Deduct 630 from 691 and we're left with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

On to step 7:
The number 70 fits into 610 8 times, leaving a remainder of 50.
Put 8 as the next digit of the answer. 
Result so far: 2219.8
If we subtract 560 from 610, 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.

On to step 8:
500 divided by 70 is 7 with a remainder of 10.
The next digit of our result is 7. 
Result so far: 2219.87
Subtract 490 from 500 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.

Step 9:
70 can be fit into 100 1 times, resulting in a remainder of 30.
Write down 1 as next digit of the result. 
Result so far: 2219.871
Subtracting 70 from 100 leaves us 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.

Advancing to step 10:
When dividing 300 by 70, we get 4 with a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 2219.8714
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.

Going ahead to step 11:
70 can be fit into 200 2 times, resulting in a remainder of 60.
Record the quotient 2 as the next digit in the result. 
Result so far: 2219.87142
Deduct 140 from 200 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 12:
600 divided by 70 is 8 with a remainder of 40.
The next digit of our result is 8. 
Result so far: 2219.871428
Subtracting 560 from 600 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.

Going ahead to step 13:
When dividing 400 by 70, we get 5 with a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 2219.8714285
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.

Moving on to step 14:
500 divided by 70 is 7 with a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 2219.87142857
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.

The quotient of the division is 2219.87142857, and the remainder is 1e-08.
