We divide 51815070 by 673
The aim is to understand the frequency of 673 in 51815070.

Moving on to step 1:
5 divided by 673 is 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
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 / 673

On to step 2:
673 can be fit into 51 0 times, resulting in a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 51, we end up with 51.
Bring next digit (8) of the dividend behind the 51 and repeat the process: 518 / 673

Advancing to step 3:
If we divide 518 by 673, we get 0 and a remainder of 518.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 518, we get 518.
Grab the next digit (1) from the dividend, add it to 518, then carry on: 5181 / 673

Going ahead to step 4:
673 can be fit into 5181 7 times, resulting in a remainder of 470.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we subtract 4711 from 5181, we get 470.
Take the next digit (5) from the dividend and append it to 470, then repeat: 4705 / 673

On to step 5:
673 can be fit into 4705 6 times, resulting in a remainder of 667.
Use 6 as the next digit of our solution. 
Result so far: 76.0
If we take 4038 away from 4705, we end up with 667.
Bring next digit (0) of the dividend behind the 667 and repeat the process: 6670 / 673

Moving on to step 6:
6670 divided by 673 is 9 with a remainder of 613.
Record the quotient 9 as the next digit in the result. 
Result so far: 769.0
If we take 6057 away from 6670, we end up with 613.
Grab the next digit (7) from the dividend, add it to 613, then carry on: 6137 / 673

Advancing to step 7:
673 goes into 6137 9 times with a remainder of 80.
Use 9 as the next digit of our solution. 
Result so far: 7699.0
Subtract 6057 from 6137 to get 80.
Take the next digit (0) from the dividend and append it to 80, then repeat: 800 / 673

Advancing to step 8:
673 can be fit into 800 1 times, resulting in a remainder of 127.
Use 1 as the next digit of our solution. 
Result so far: 76991.0
The remainder is 127 after subtracting 673 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Let's proceed to step 9:
If we divide 1270 by 673, we get 1 and a remainder of 597.
Record the quotient 1 as the next digit in the result. 
Result so far: 76991.1
Deduct 673 from 1270 and we're left with 597.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5970, and continue the process.

On to step 10:
When dividing 5970 by 673, we get 8 with a remainder of 586.
The next digit of our result is 8. 
Result so far: 76991.18
The remainder is 586 after subtracting 5384 from 5970.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5860, and continue the process.

On to step 11:
673 can be fit into 5860 8 times, resulting in a remainder of 476.
Use 8 as the next digit of our solution. 
Result so far: 76991.188
Subtract 5384 from 5860 to get 476.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

The quotient of the division is 76991.188, and the remainder is 0.0476.
