86206488 ÷ 70 
Our goal is to divide 86206488 by 70.

Moving on to step 1:
The number 70 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 70

Moving on to step 2:
The number 70 fits into 86 1 times, leaving a remainder of 16.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 70 from 86 to get 16.
Fetch the next digit (2) from the dividend, attach it to 16 and continue: 162 / 70

Moving on to step 3:
70 can be fit into 162 2 times, resulting in a remainder of 22.
The next digit of our result is 2. 
Result so far: 12.0
Subtract 140 from 162 to get 22.
Grab the next digit (0) from the dividend, add it to 22, then carry on: 220 / 70

On to step 4:
If we divide 220 by 70, we get 3 and a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 123.0
Subtracting 210 from 220 leaves us with 10.
Include the next digit (6) from the dividend after 10, then repeat: 106 / 70

Moving on to step 5:
106 divided by 70 is 1 with a remainder of 36.
The number 1 becomes the next digit in our result. 
Result so far: 1231.0
Subtracting 70 from 106 leaves us with 36.
Include the next digit (4) from the dividend after 36, then repeat: 364 / 70

Going ahead to step 6:
The number 70 fits into 364 5 times, leaving a remainder of 14.
The number 5 becomes the next digit in our result. 
Result so far: 12315.0
Deduct 350 from 364 and we're left with 14.
Bring next digit (8) of the dividend behind the 14 and repeat the process: 148 / 70

Moving on to step 7:
If we divide 148 by 70, we get 2 and a remainder of 8.
The next digit of our result is 2. 
Result so far: 123152.0
If we take 140 away from 148, we end up with 8.
Grab the next digit (8) from the dividend, add it to 8, then carry on: 88 / 70

On to step 8:
88 divided by 70 is 1 with a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 1231521.0
The remainder is 18 after subtracting 70 from 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 9:
70 goes into 180 2 times with a remainder of 40.
Use 2 as the next digit of our solution. 
Result so far: 1231521.2
The remainder is 40 after subtracting 140 from 180.
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 10:
The number 70 fits into 400 5 times, leaving a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 1231521.25
Subtract 350 from 400 to 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.

Moving on to step 11:
70 goes into 500 7 times with a remainder of 10.
Put 7 as the next digit of the answer. 
Result so far: 1231521.257
If we take 490 away from 500, we end up 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 12:
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: 1231521.2571
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.

Moving on to step 13:
When dividing 300 by 70, we get 4 with a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 1231521.25714
Subtracting 280 from 300 leaves us 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.

Moving on to step 14:
200 divided by 70 is 2 with a remainder of 60.
Put 2 as the next digit of the answer. 
Result so far: 1231521.257142
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.

Going ahead to step 15:
The number 70 fits into 600 8 times, leaving a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 1231521.2571428
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.

Step 16:
When dividing 400 by 70, we get 5 with a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 1231521.25714285
Subtracting 350 from 400 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Our division results in 1231521.25714285 with a remaining 5e-08.
