86976849 ÷ 626 
We want to divide 86976849 by 626.

Step 1:
When dividing 8 by 626, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 626

Moving on to step 2:
If we divide 86 by 626, we get 0 and a remainder of 86.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 86 to get 86.
Bring next digit (9) of the dividend behind the 86 and repeat the process: 869 / 626

Let's proceed to step 3:
869 divided by 626 is 1 with a remainder of 243.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 626 from 869 leaves us with 243.
Append the next digit (7) from the dividend to 243 and continue with: 2437 / 626

Advancing to step 4:
If we divide 2437 by 626, we get 3 and a remainder of 559.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Subtract 1878 from 2437 to get 559.
Include the next digit (6) from the dividend after 559, then repeat: 5596 / 626

Advancing to step 5:
626 goes into 5596 8 times with a remainder of 588.
Put 8 as the next digit of the answer. 
Result so far: 138.0
If we take 5008 away from 5596, we end up with 588.
Include the next digit (8) from the dividend after 588, then repeat: 5888 / 626

Advancing to step 6:
626 goes into 5888 9 times with a remainder of 254.
Put 9 as the next digit of the answer. 
Result so far: 1389.0
The remainder is 254 after subtracting 5634 from 5888.
Append the next digit (4) from the dividend to 254 and continue with: 2544 / 626

Advancing to step 7:
626 can be fit into 2544 4 times, resulting in a remainder of 40.
The number 4 becomes the next digit in our result. 
Result so far: 13894.0
Subtracting 2504 from 2544 leaves us with 40.
Take the next digit (9) from the dividend and append it to 40, then repeat: 409 / 626

Going ahead to step 8:
626 goes into 409 0 times with a remainder of 409.
Use 0 as the next digit of our solution. 
Result so far: 138940.0
If we take 0 away from 409, we end up with 409.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4090, and continue the process.

Moving on to step 9:
When dividing 4090 by 626, we get 6 with a remainder of 334.
The number 6 becomes the next digit in our result. 
Result so far: 138940.6
The remainder is 334 after subtracting 3756 from 4090.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

Going ahead to step 10:
626 goes into 3340 5 times with a remainder of 210.
Use 5 as the next digit of our solution. 
Result so far: 138940.65
If we take 3130 away from 3340, we end up with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Going ahead to step 11:
626 goes into 2100 3 times with a remainder of 222.
Put 3 as the next digit of the answer. 
Result so far: 138940.653
If we take 1878 away from 2100, we end up with 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Moving on to step 12:
626 can be fit into 2220 3 times, resulting in a remainder of 342.
Write down 3 as next digit of the result. 
Result so far: 138940.6533
Subtracting 1878 from 2220 leaves us with 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

The quotient of the division is 138940.6533, and the remainder is 0.00342.
