We look at the division of 46399941 by 690 
The aim is to understand the frequency of 690 in 46399941.

On to step 1:
690 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (6) from the dividend, attach it to 4 and continue: 46 / 690

On to step 2:
46 divided by 690 is 0 with a remainder of 46.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 46, we get 46.
Append the next digit (3) from the dividend to 46 and continue with: 463 / 690

Advancing to step 3:
463 divided by 690 is 0 with a remainder of 463.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 463 leaves us with 463.
Include the next digit (9) from the dividend after 463, then repeat: 4639 / 690

On to step 4:
690 goes into 4639 6 times with a remainder of 499.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we take 4140 away from 4639, we end up with 499.
Append the next digit (9) from the dividend to 499 and continue with: 4999 / 690

On to step 5:
4999 divided by 690 is 7 with a remainder of 169.
Write down 7 as next digit of the result. 
Result so far: 67.0
If we take 4830 away from 4999, we end up with 169.
Grab the next digit (9) from the dividend, add it to 169, then carry on: 1699 / 690

Going ahead to step 6:
690 can be fit into 1699 2 times, resulting in a remainder of 319.
Record the quotient 2 as the next digit in the result. 
Result so far: 672.0
Deduct 1380 from 1699 and we're left with 319.
Append the next digit (4) from the dividend to 319 and continue with: 3194 / 690

Advancing to step 7:
690 can be fit into 3194 4 times, resulting in a remainder of 434.
Use 4 as the next digit of our solution. 
Result so far: 6724.0
Deduct 2760 from 3194 and we're left with 434.
Append the next digit (1) from the dividend to 434 and continue with: 4341 / 690

Moving on to step 8:
When dividing 4341 by 690, we get 6 with a remainder of 201.
The next digit of our result is 6. 
Result so far: 67246.0
Subtracting 4140 from 4341 leaves us with 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

Going ahead to step 9:
When dividing 2010 by 690, we get 2 with a remainder of 630.
Put 2 as the next digit of the answer. 
Result so far: 67246.2
Subtract 1380 from 2010 to get 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

Step 10:
The number 690 fits into 6300 9 times, leaving a remainder of 90.
The next digit of our result is 9. 
Result so far: 67246.29
Subtract 6210 from 6300 to get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

On to step 11:
If we divide 900 by 690, we get 1 and a remainder of 210.
Use 1 as the next digit of our solution. 
Result so far: 67246.291
If we subtract 690 from 900, we get 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 12:
When dividing 2100 by 690, we get 3 with a remainder of 30.
Use 3 as the next digit of our solution. 
Result so far: 67246.2913
Deduct 2070 from 2100 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 13:
The number 690 fits into 300 0 times, leaving a remainder of 300.
The next digit of our result is 0. 
Result so far: 67246.2913
If we take 0 away from 300, we end up with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Going ahead to step 14:
3000 divided by 690 is 4 with a remainder of 240.
The number 4 becomes the next digit in our result. 
Result so far: 67246.291304
Subtract 2760 from 3000 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Moving on to step 15:
690 can be fit into 2400 3 times, resulting in a remainder of 330.
The next digit of our result is 3. 
Result so far: 67246.2913043
The remainder is 330 after subtracting 2070 from 2400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Advancing to step 16:
690 can be fit into 3300 4 times, resulting in a remainder of 540.
Record the quotient 4 as the next digit in the result. 
Result so far: 67246.29130434
If we subtract 2760 from 3300, we get 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

The quotient of the division is 67246.29130434, and the remainder is 5.4e-07.
