Let's divide 90651918 by 673
The aim is to understand the frequency of 673 in 90651918.

Going ahead to step 1:
673 can be fit into 9 0 times, resulting in a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 673

Step 2:
673 goes into 90 0 times with a remainder of 90.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 90, we get 90.
Bring next digit (6) of the dividend behind the 90 and repeat the process: 906 / 673

Step 3:
If we divide 906 by 673, we get 1 and a remainder of 233.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 673 from 906 leaves us with 233.
Bring next digit (5) of the dividend behind the 233 and repeat the process: 2335 / 673

On to step 4:
2335 divided by 673 is 3 with a remainder of 316.
Put 3 as the next digit of the answer. 
Result so far: 13.0
The remainder is 316 after subtracting 2019 from 2335.
Append the next digit (1) from the dividend to 316 and continue with: 3161 / 673

Advancing to step 5:
3161 divided by 673 is 4 with a remainder of 469.
Put 4 as the next digit of the answer. 
Result so far: 134.0
Deduct 2692 from 3161 and we're left with 469.
Take the next digit (9) from the dividend and append it to 469, then repeat: 4699 / 673

Step 6:
4699 divided by 673 is 6 with a remainder of 661.
Use 6 as the next digit of our solution. 
Result so far: 1346.0
Subtract 4038 from 4699 to get 661.
Fetch the next digit (1) from the dividend, attach it to 661 and continue: 6611 / 673

On to step 7:
673 goes into 6611 9 times with a remainder of 554.
The number 9 becomes the next digit in our result. 
Result so far: 13469.0
Deduct 6057 from 6611 and we're left with 554.
Take the next digit (8) from the dividend and append it to 554, then repeat: 5548 / 673

On to step 8:
When dividing 5548 by 673, we get 8 with a remainder of 164.
The next digit of our result is 8. 
Result so far: 134698.0
Deduct 5384 from 5548 and we're left with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Step 9:
If we divide 1640 by 673, we get 2 and a remainder of 294.
Write down 2 as next digit of the result. 
Result so far: 134698.2
Deduct 1346 from 1640 and we're left with 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

On to step 10:
2940 divided by 673 is 4 with a remainder of 248.
The next digit of our result is 4. 
Result so far: 134698.24
Deduct 2692 from 2940 and we're left with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Let's proceed to step 11:
673 goes into 2480 3 times with a remainder of 461.
Record the quotient 3 as the next digit in the result. 
Result so far: 134698.243
The remainder is 461 after subtracting 2019 from 2480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4610, and continue the process.

Advancing to step 12:
When dividing 4610 by 673, we get 6 with a remainder of 572.
Write down 6 as next digit of the result. 
Result so far: 134698.2436
Deduct 4038 from 4610 and we're left with 572.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5720, and continue the process.

On to step 13:
5720 divided by 673 is 8 with a remainder of 336.
Record the quotient 8 as the next digit in the result. 
Result so far: 134698.24368
Subtract 5384 from 5720 to get 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Moving on to step 14:
The number 673 fits into 3360 4 times, leaving a remainder of 668.
Record the quotient 4 as the next digit in the result. 
Result so far: 134698.243684
Subtract 2692 from 3360 to get 668.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6680, and continue the process.

Going ahead to step 15:
673 can be fit into 6680 9 times, resulting in a remainder of 623.
Put 9 as the next digit of the answer. 
Result so far: 134698.2436849
Deduct 6057 from 6680 and we're left with 623.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6230, and continue the process.

Let's proceed to step 16:
The number 673 fits into 6230 9 times, leaving a remainder of 173.
The next digit of our result is 9. 
Result so far: 134698.24368499
Subtract 6057 from 6230 to get 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

After the division, we end up with 134698.24368499 and a remainder of 1.73e-07.
