We look at the division of 51489147 by 705 
The aim is to understand the frequency of 705 in 51489147.

On to step 1:
If we divide 5 by 705, we get 0 and a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 705

Advancing to step 2:
705 can be fit into 51 0 times, resulting in 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 / 705

On to step 3:
705 can be fit into 514 0 times, resulting in a remainder of 514.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 514 to get 514.
Bring next digit (8) of the dividend behind the 514 and repeat the process: 5148 / 705

Let's proceed to step 4:
The number 705 fits into 5148 7 times, leaving a remainder of 213.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Deduct 4935 from 5148 and we're left with 213.
Append the next digit (9) from the dividend to 213 and continue with: 2139 / 705

Going ahead to step 5:
705 goes into 2139 3 times with a remainder of 24.
Use 3 as the next digit of our solution. 
Result so far: 73.0
Subtracting 2115 from 2139 leaves us with 24.
Include the next digit (1) from the dividend after 24, then repeat: 241 / 705

Moving on to step 6:
When dividing 241 by 705, we get 0 with a remainder of 241.
The next digit of our result is 0. 
Result so far: 730.0
Subtract 0 from 241 to get 241.
Fetch the next digit (4) from the dividend, attach it to 241 and continue: 2414 / 705

Moving on to step 7:
2414 divided by 705 is 3 with a remainder of 299.
Write down 3 as next digit of the result. 
Result so far: 7303.0
The remainder is 299 after subtracting 2115 from 2414.
Append the next digit (7) from the dividend to 299 and continue with: 2997 / 705

On to step 8:
2997 divided by 705 is 4 with a remainder of 177.
The next digit of our result is 4. 
Result so far: 73034.0
The remainder is 177 after subtracting 2820 from 2997.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

Step 9:
705 can be fit into 1770 2 times, resulting in a remainder of 360.
Put 2 as the next digit of the answer. 
Result so far: 73034.2
Subtracting 1410 from 1770 leaves us with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Step 10:
3600 divided by 705 is 5 with a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 73034.25
Subtracting 3525 from 3600 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 11:
The number 705 fits into 750 1 times, leaving a remainder of 45.
Use 1 as the next digit of our solution. 
Result so far: 73034.251
Subtract 705 from 750 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 12:
When dividing 450 by 705, we get 0 with a remainder of 450.
Put 0 as the next digit of the answer. 
Result so far: 73034.251
Subtracting 0 from 450 leaves us with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Let's proceed to step 13:
4500 divided by 705 is 6 with a remainder of 270.
The number 6 becomes the next digit in our result. 
Result so far: 73034.25106
Deduct 4230 from 4500 and we're left with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Moving on to step 14:
If we divide 2700 by 705, we get 3 and a remainder of 585.
Put 3 as the next digit of the answer. 
Result so far: 73034.251063
Subtract 2115 from 2700 to get 585.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5850, and continue the process.

Moving on to step 15:
705 can be fit into 5850 8 times, resulting in a remainder of 210.
Put 8 as the next digit of the answer. 
Result so far: 73034.2510638
If we take 5640 away from 5850, 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.

Advancing to step 16:
The number 705 fits into 2100 2 times, leaving a remainder of 690.
Use 2 as the next digit of our solution. 
Result so far: 73034.25106382
If we take 1410 away from 2100, we end up with 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6900, and continue the process.

The quotient of the division is 73034.25106382, and the remainder is 6.9e-07.
