86913015 divided by 122 
We're looking to find how many times 122 goes into 86913015.

Advancing to step 1:
The number 122 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 122

Moving on to step 2:
If we divide 86 by 122, 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.
Bring next digit (9) of the dividend behind the 86 and repeat the process: 869 / 122

Moving on to step 3:
The number 122 fits into 869 7 times, leaving a remainder of 15.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we take 854 away from 869, we end up with 15.
Include the next digit (1) from the dividend after 15, then repeat: 151 / 122

On to step 4:
If we divide 151 by 122, we get 1 and a remainder of 29.
The next digit of our result is 1. 
Result so far: 71.0
Deduct 122 from 151 and we're left with 29.
Grab the next digit (3) from the dividend, add it to 29, then carry on: 293 / 122

Step 5:
293 divided by 122 is 2 with a remainder of 49.
The next digit of our result is 2. 
Result so far: 712.0
Subtract 244 from 293 to get 49.
Grab the next digit (0) from the dividend, add it to 49, then carry on: 490 / 122

Let's proceed to step 6:
The number 122 fits into 490 4 times, leaving a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 7124.0
If we subtract 488 from 490, we get 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 122

Advancing to step 7:
21 divided by 122 is 0 with a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 71240.0
The remainder is 21 after subtracting 0 from 21.
Bring next digit (5) of the dividend behind the 21 and repeat the process: 215 / 122

Let's proceed to step 8:
The number 122 fits into 215 1 times, leaving a remainder of 93.
Use 1 as the next digit of our solution. 
Result so far: 712401.0
If we subtract 122 from 215, we get 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Going ahead to step 9:
If we divide 930 by 122, we get 7 and a remainder of 76.
Record the quotient 7 as the next digit in the result. 
Result so far: 712401.7
Subtracting 854 from 930 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 10:
122 goes into 760 6 times with a remainder of 28.
Record the quotient 6 as the next digit in the result. 
Result so far: 712401.76
Subtract 732 from 760 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 11:
122 goes into 280 2 times with a remainder of 36.
The next digit of our result is 2. 
Result so far: 712401.762
Subtract 244 from 280 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 12:
If we divide 360 by 122, we get 2 and a remainder of 116.
Write down 2 as next digit of the result. 
Result so far: 712401.7622
If we subtract 244 from 360, we get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

After the division, we end up with 712401.7622 and a remainder of 0.00116.
