We're dividing 77419015 by 86 
Our goal is to divide 77419015 by 86.

Let's proceed to step 1:
If we divide 7 by 86, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 86

Going ahead to step 2:
86 can be fit into 77 0 times, resulting in a remainder of 77.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 77 leaves us with 77.
Take the next digit (4) from the dividend and append it to 77, then repeat: 774 / 86

Advancing to step 3:
774 divided by 86 is 9 with a remainder of 0.
The next digit of our result is 9. 
Result so far: 9.0
If we subtract 774 from 774, we get 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 86

Going ahead to step 4:
If we divide 1 by 86, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 90.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 86

Advancing to step 5:
86 goes into 19 0 times with a remainder of 19.
The number 0 becomes the next digit in our result. 
Result so far: 900.0
The remainder is 19 after subtracting 0 from 19.
Fetch the next digit (0) from the dividend, attach it to 19 and continue: 190 / 86

On to step 6:
86 can be fit into 190 2 times, resulting in a remainder of 18.
Record the quotient 2 as the next digit in the result. 
Result so far: 9002.0
If we take 172 away from 190, we end up with 18.
Include the next digit (1) from the dividend after 18, then repeat: 181 / 86

Step 7:
86 goes into 181 2 times with a remainder of 9.
Put 2 as the next digit of the answer. 
Result so far: 90022.0
Deduct 172 from 181 and we're left with 9.
Grab the next digit (5) from the dividend, add it to 9, then carry on: 95 / 86

Moving on to step 8:
86 can be fit into 95 1 times, resulting in a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 900221.0
If we subtract 86 from 95, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 9:
If we divide 90 by 86, we get 1 and a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 900221.1
The remainder is 4 after subtracting 86 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 10:
86 goes into 40 0 times with a remainder of 40.
The next digit of our result is 0. 
Result so far: 900221.1
If we take 0 away from 40, we end up 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.

Moving on to step 11:
If we divide 400 by 86, we get 4 and a remainder of 56.
The number 4 becomes the next digit in our result. 
Result so far: 900221.104
If we take 344 away from 400, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 12:
86 goes into 560 6 times with a remainder of 44.
Put 6 as the next digit of the answer. 
Result so far: 900221.1046
Subtracting 516 from 560 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 13:
440 divided by 86 is 5 with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 900221.10465
The remainder is 10 after subtracting 430 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 14:
86 goes into 100 1 times with a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 900221.104651
Subtract 86 from 100 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 15:
86 can be fit into 140 1 times, resulting in a remainder of 54.
The number 1 becomes the next digit in our result. 
Result so far: 900221.1046511
If we take 86 away from 140, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

After the division, we end up with 900221.1046511 and a remainder of 5.4e-07.
