51486318 ÷ 988 
The aim is to understand the frequency of 988 in 51486318.

Moving on to step 1:
If we divide 5 by 988, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 988

Advancing to step 2:
988 goes into 51 0 times with a remainder of 51.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 51, we end up with 51.
Include the next digit (4) from the dividend after 51, then repeat: 514 / 988

Moving on to step 3:
988 goes into 514 0 times with a remainder of 514.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 514, we end up with 514.
Grab the next digit (8) from the dividend, add it to 514, then carry on: 5148 / 988

Going ahead to step 4:
5148 divided by 988 is 5 with a remainder of 208.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtract 4940 from 5148 to get 208.
Append the next digit (6) from the dividend to 208 and continue with: 2086 / 988

Advancing to step 5:
If we divide 2086 by 988, we get 2 and a remainder of 110.
The number 2 becomes the next digit in our result. 
Result so far: 52.0
Subtracting 1976 from 2086 leaves us with 110.
Take the next digit (3) from the dividend and append it to 110, then repeat: 1103 / 988

On to step 6:
1103 divided by 988 is 1 with a remainder of 115.
Put 1 as the next digit of the answer. 
Result so far: 521.0
If we take 988 away from 1103, we end up with 115.
Include the next digit (1) from the dividend after 115, then repeat: 1151 / 988

Let's proceed to step 7:
988 can be fit into 1151 1 times, resulting in a remainder of 163.
Put 1 as the next digit of the answer. 
Result so far: 5211.0
If we subtract 988 from 1151, we get 163.
Fetch the next digit (8) from the dividend, attach it to 163 and continue: 1638 / 988

Going ahead to step 8:
When dividing 1638 by 988, we get 1 with a remainder of 650.
The next digit of our result is 1. 
Result so far: 52111.0
Subtracting 988 from 1638 leaves us with 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

Step 9:
988 goes into 6500 6 times with a remainder of 572.
Write down 6 as next digit of the result. 
Result so far: 52111.6
If we subtract 5928 from 6500, we get 572.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5720, and continue the process.

Moving on to step 10:
988 can be fit into 5720 5 times, resulting in a remainder of 780.
Put 5 as the next digit of the answer. 
Result so far: 52111.65
If we subtract 4940 from 5720, we get 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7800, and continue the process.

Let's proceed to step 11:
988 can be fit into 7800 7 times, resulting in a remainder of 884.
Write down 7 as next digit of the result. 
Result so far: 52111.657
If we take 6916 away from 7800, we end up with 884.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8840, and continue the process.

Advancing to step 12:
When dividing 8840 by 988, we get 8 with a remainder of 936.
Write down 8 as next digit of the result. 
Result so far: 52111.6578
The remainder is 936 after subtracting 7904 from 8840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9360, and continue the process.

On to step 13:
988 can be fit into 9360 9 times, resulting in a remainder of 468.
Record the quotient 9 as the next digit in the result. 
Result so far: 52111.65789
The remainder is 468 after subtracting 8892 from 9360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

Step 14:
988 goes into 4680 4 times with a remainder of 728.
The number 4 becomes the next digit in our result. 
Result so far: 52111.657894
Subtract 3952 from 4680 to get 728.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7280, and continue the process.

On to step 15:
When dividing 7280 by 988, we get 7 with a remainder of 364.
Use 7 as the next digit of our solution. 
Result so far: 52111.6578947
If we take 6916 away from 7280, we end up with 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

On to step 16:
The number 988 fits into 3640 3 times, leaving a remainder of 676.
Write down 3 as next digit of the result. 
Result so far: 52111.65789473
The remainder is 676 after subtracting 2964 from 3640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6760, and continue the process.

The quotient of the division is 52111.65789473, and the remainder is 6.76e-07.
