We look at the division of 86859259 by 212 
We want to divide 86859259 by 212.

Going ahead to step 1:
The number 212 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 212

Moving on to step 2:
If we divide 86 by 212, we get 0 and a remainder of 86.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 86 to get 86.
Include the next digit (8) from the dividend after 86, then repeat: 868 / 212

On to step 3:
If we divide 868 by 212, we get 4 and a remainder of 20.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 848 from 868 and we're left with 20.
Take the next digit (5) from the dividend and append it to 20, then repeat: 205 / 212

Let's proceed to step 4:
212 goes into 205 0 times with a remainder of 205.
Put 0 as the next digit of the answer. 
Result so far: 40.0
The remainder is 205 after subtracting 0 from 205.
Take the next digit (9) from the dividend and append it to 205, then repeat: 2059 / 212

Let's proceed to step 5:
If we divide 2059 by 212, we get 9 and a remainder of 151.
The next digit of our result is 9. 
Result so far: 409.0
If we take 1908 away from 2059, we end up with 151.
Fetch the next digit (2) from the dividend, attach it to 151 and continue: 1512 / 212

Step 6:
The number 212 fits into 1512 7 times, leaving a remainder of 28.
The next digit of our result is 7. 
Result so far: 4097.0
The remainder is 28 after subtracting 1484 from 1512.
Fetch the next digit (5) from the dividend, attach it to 28 and continue: 285 / 212

On to step 7:
The number 212 fits into 285 1 times, leaving a remainder of 73.
Use 1 as the next digit of our solution. 
Result so far: 40971.0
If we subtract 212 from 285, we get 73.
Include the next digit (9) from the dividend after 73, then repeat: 739 / 212

Moving on to step 8:
If we divide 739 by 212, we get 3 and a remainder of 103.
The next digit of our result is 3. 
Result so far: 409713.0
If we subtract 636 from 739, we get 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

On to step 9:
If we divide 1030 by 212, we get 4 and a remainder of 182.
Use 4 as the next digit of our solution. 
Result so far: 409713.4
Deduct 848 from 1030 and we're left with 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Step 10:
When dividing 1820 by 212, we get 8 with a remainder of 124.
The next digit of our result is 8. 
Result so far: 409713.48
Subtract 1696 from 1820 to get 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Let's proceed to step 11:
When dividing 1240 by 212, we get 5 with a remainder of 180.
Write down 5 as next digit of the result. 
Result so far: 409713.485
If we subtract 1060 from 1240, we get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Let's proceed to step 12:
When dividing 1800 by 212, we get 8 with a remainder of 104.
Record the quotient 8 as the next digit in the result. 
Result so far: 409713.4858
If we take 1696 away from 1800, we end up with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Step 13:
1040 divided by 212 is 4 with a remainder of 192.
Put 4 as the next digit of the answer. 
Result so far: 409713.48584
Subtract 848 from 1040 to get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Moving on to step 14:
212 can be fit into 1920 9 times, resulting in a remainder of 12.
Put 9 as the next digit of the answer. 
Result so far: 409713.485849
If we subtract 1908 from 1920, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 15:
The number 212 fits into 120 0 times, leaving a remainder of 120.
Use 0 as the next digit of our solution. 
Result so far: 409713.485849
Subtracting 0 from 120 leaves us 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.

Going ahead to step 16:
212 can be fit into 1200 5 times, resulting in a remainder of 140.
Use 5 as the next digit of our solution. 
Result so far: 409713.48584905
Subtracting 1060 from 1200 leaves us with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Our division results in 409713.48584905 with a remaining 1.4e-07.
