55585931 divided by 986 
The aim is to understand the frequency of 986 in 55585931.

Let's proceed to step 1:
When dividing 5 by 986, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 986

Step 2:
55 divided by 986 is 0 with a remainder of 55.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 55, we get 55.
Grab the next digit (5) from the dividend, add it to 55, then carry on: 555 / 986

Going ahead to step 3:
986 goes into 555 0 times with a remainder of 555.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 555 leaves us with 555.
Append the next digit (8) from the dividend to 555 and continue with: 5558 / 986

On to step 4:
5558 divided by 986 is 5 with a remainder of 628.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Deduct 4930 from 5558 and we're left with 628.
Take the next digit (5) from the dividend and append it to 628, then repeat: 6285 / 986

Advancing to step 5:
The number 986 fits into 6285 6 times, leaving a remainder of 369.
Write down 6 as next digit of the result. 
Result so far: 56.0
Subtracting 5916 from 6285 leaves us with 369.
Fetch the next digit (9) from the dividend, attach it to 369 and continue: 3699 / 986

Let's proceed to step 6:
986 goes into 3699 3 times with a remainder of 741.
Put 3 as the next digit of the answer. 
Result so far: 563.0
Subtracting 2958 from 3699 leaves us with 741.
Fetch the next digit (3) from the dividend, attach it to 741 and continue: 7413 / 986

Step 7:
7413 divided by 986 is 7 with a remainder of 511.
Record the quotient 7 as the next digit in the result. 
Result so far: 5637.0
If we subtract 6902 from 7413, we get 511.
Append the next digit (1) from the dividend to 511 and continue with: 5111 / 986

Step 8:
The number 986 fits into 5111 5 times, leaving a remainder of 181.
Write down 5 as next digit of the result. 
Result so far: 56375.0
Subtract 4930 from 5111 to get 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

On to step 9:
986 can be fit into 1810 1 times, resulting in a remainder of 824.
Use 1 as the next digit of our solution. 
Result so far: 56375.1
Subtracting 986 from 1810 leaves us with 824.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8240, and continue the process.

On to step 10:
986 goes into 8240 8 times with a remainder of 352.
Write down 8 as next digit of the result. 
Result so far: 56375.18
If we subtract 7888 from 8240, we get 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Advancing to step 11:
986 can be fit into 3520 3 times, resulting in a remainder of 562.
The next digit of our result is 3. 
Result so far: 56375.183
The remainder is 562 after subtracting 2958 from 3520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5620, and continue the process.

Moving on to step 12:
986 goes into 5620 5 times with a remainder of 690.
Put 5 as the next digit of the answer. 
Result so far: 56375.1835
Subtract 4930 from 5620 to get 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6900, and continue the process.

Advancing to step 13:
6900 divided by 986 is 6 with a remainder of 984.
Write down 6 as next digit of the result. 
Result so far: 56375.18356
Subtracting 5916 from 6900 leaves us with 984.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9840, and continue the process.

Going ahead to step 14:
986 can be fit into 9840 9 times, resulting in a remainder of 966.
Put 9 as the next digit of the answer. 
Result so far: 56375.183569
Subtracting 8874 from 9840 leaves us with 966.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9660, and continue the process.

Step 15:
The number 986 fits into 9660 9 times, leaving a remainder of 786.
Put 9 as the next digit of the answer. 
Result so far: 56375.1835699
Deduct 8874 from 9660 and we're left with 786.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7860, and continue the process.

After the division, we end up with 56375.1835699 and a remainder of 7.86e-06.
