12397217 divided by 986 
Our goal is to divide 12397217 by 986.

Step 1:
If we divide 1 by 986, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 986

Moving on to step 2:
When dividing 12 by 986, we get 0 with a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Append the next digit (3) from the dividend to 12 and continue with: 123 / 986

Let's proceed to step 3:
123 divided by 986 is 0 with a remainder of 123.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 123, we end up with 123.
Fetch the next digit (9) from the dividend, attach it to 123 and continue: 1239 / 986

Moving on to step 4:
1239 divided by 986 is 1 with a remainder of 253.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 986 from 1239 and we're left with 253.
Append the next digit (7) from the dividend to 253 and continue with: 2537 / 986

Let's proceed to step 5:
2537 divided by 986 is 2 with a remainder of 565.
Use 2 as the next digit of our solution. 
Result so far: 12.0
If we subtract 1972 from 2537, we get 565.
Fetch the next digit (2) from the dividend, attach it to 565 and continue: 5652 / 986

Going ahead to step 6:
5652 divided by 986 is 5 with a remainder of 722.
The next digit of our result is 5. 
Result so far: 125.0
Subtract 4930 from 5652 to get 722.
Take the next digit (1) from the dividend and append it to 722, then repeat: 7221 / 986

Let's proceed to step 7:
If we divide 7221 by 986, we get 7 and a remainder of 319.
Use 7 as the next digit of our solution. 
Result so far: 1257.0
Subtracting 6902 from 7221 leaves us with 319.
Include the next digit (7) from the dividend after 319, then repeat: 3197 / 986

Step 8:
986 can be fit into 3197 3 times, resulting in a remainder of 239.
Put 3 as the next digit of the answer. 
Result so far: 12573.0
If we subtract 2958 from 3197, we get 239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

Step 9:
When dividing 2390 by 986, we get 2 with a remainder of 418.
Write down 2 as next digit of the result. 
Result so far: 12573.2
If we subtract 1972 from 2390, we get 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

Going ahead to step 10:
986 can be fit into 4180 4 times, resulting in a remainder of 236.
Put 4 as the next digit of the answer. 
Result so far: 12573.24
The remainder is 236 after subtracting 3944 from 4180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Advancing to step 11:
When dividing 2360 by 986, we get 2 with a remainder of 388.
The next digit of our result is 2. 
Result so far: 12573.242
The remainder is 388 after subtracting 1972 from 2360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Let's proceed to step 12:
986 goes into 3880 3 times with a remainder of 922.
Put 3 as the next digit of the answer. 
Result so far: 12573.2423
Deduct 2958 from 3880 and we're left with 922.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9220, and continue the process.

Going ahead to step 13:
If we divide 9220 by 986, we get 9 and a remainder of 346.
Write down 9 as next digit of the result. 
Result so far: 12573.24239
Subtracting 8874 from 9220 leaves us with 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

Advancing to step 14:
986 goes into 3460 3 times with a remainder of 502.
Use 3 as the next digit of our solution. 
Result so far: 12573.242393
Subtract 2958 from 3460 to get 502.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5020, and continue the process.

Moving on to step 15:
5020 divided by 986 is 5 with a remainder of 90.
The next digit of our result is 5. 
Result so far: 12573.2423935
Subtract 4930 from 5020 to get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Advancing to step 16:
If we divide 900 by 986, we get 0 and a remainder of 900.
Record the quotient 0 as the next digit in the result. 
Result so far: 12573.2423935
If we take 0 away from 900, we end up with 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9000, and continue the process.

After the division, we end up with 12573.2423935 and a remainder of 9e-07.
