We're dividing 86669479 by 526 
We want to divide 86669479 by 526.

On to step 1:
8 divided by 526 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 526

Step 2:
If we divide 86 by 526, we get 0 and a remainder of 86.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 86 to get 86.
Grab the next digit (6) from the dividend, add it to 86, then carry on: 866 / 526

Let's proceed to step 3:
866 divided by 526 is 1 with a remainder of 340.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 526 from 866 to get 340.
Bring next digit (6) of the dividend behind the 340 and repeat the process: 3406 / 526

Let's proceed to step 4:
526 goes into 3406 6 times with a remainder of 250.
Write down 6 as next digit of the result. 
Result so far: 16.0
If we take 3156 away from 3406, we end up with 250.
Bring next digit (9) of the dividend behind the 250 and repeat the process: 2509 / 526

Going ahead to step 5:
2509 divided by 526 is 4 with a remainder of 405.
Use 4 as the next digit of our solution. 
Result so far: 164.0
Subtract 2104 from 2509 to get 405.
Take the next digit (4) from the dividend and append it to 405, then repeat: 4054 / 526

Going ahead to step 6:
The number 526 fits into 4054 7 times, leaving a remainder of 372.
Use 7 as the next digit of our solution. 
Result so far: 1647.0
If we take 3682 away from 4054, we end up with 372.
Bring next digit (7) of the dividend behind the 372 and repeat the process: 3727 / 526

Moving on to step 7:
526 goes into 3727 7 times with a remainder of 45.
The next digit of our result is 7. 
Result so far: 16477.0
Subtracting 3682 from 3727 leaves us with 45.
Grab the next digit (9) from the dividend, add it to 45, then carry on: 459 / 526

Advancing to step 8:
The number 526 fits into 459 0 times, leaving a remainder of 459.
Use 0 as the next digit of our solution. 
Result so far: 164770.0
Subtract 0 from 459 to get 459.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4590, and continue the process.

On to step 9:
When dividing 4590 by 526, we get 8 with a remainder of 382.
Put 8 as the next digit of the answer. 
Result so far: 164770.8
The remainder is 382 after subtracting 4208 from 4590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

Advancing to step 10:
The number 526 fits into 3820 7 times, leaving a remainder of 138.
Put 7 as the next digit of the answer. 
Result so far: 164770.87
Subtracting 3682 from 3820 leaves us with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Let's proceed to step 11:
If we divide 1380 by 526, we get 2 and a remainder of 328.
Record the quotient 2 as the next digit in the result. 
Result so far: 164770.872
Subtract 1052 from 1380 to get 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Let's proceed to step 12:
3280 divided by 526 is 6 with a remainder of 124.
Use 6 as the next digit of our solution. 
Result so far: 164770.8726
If we take 3156 away from 3280, we end up with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Moving on to step 13:
1240 divided by 526 is 2 with a remainder of 188.
The number 2 becomes the next digit in our result. 
Result so far: 164770.87262
Subtract 1052 from 1240 to get 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Let's proceed to step 14:
The number 526 fits into 1880 3 times, leaving a remainder of 302.
The number 3 becomes the next digit in our result. 
Result so far: 164770.872623
Deduct 1578 from 1880 and we're left with 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

Step 15:
The number 526 fits into 3020 5 times, leaving a remainder of 390.
Record the quotient 5 as the next digit in the result. 
Result so far: 164770.8726235
If we take 2630 away from 3020, we end up with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Going ahead to step 16:
When dividing 3900 by 526, we get 7 with a remainder of 218.
Write down 7 as next digit of the result. 
Result so far: 164770.87262357
Subtracting 3682 from 3900 leaves us with 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

The quotient of the division is 164770.87262357, and the remainder is 2.18e-07.
