29698590 ÷ 638 
The aim is to understand the frequency of 638 in 29698590.

Advancing to step 1:
638 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (9) from the dividend, add it to 2, then carry on: 29 / 638

Advancing to step 2:
29 divided by 638 is 0 with a remainder of 29.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 29, we get 29.
Grab the next digit (6) from the dividend, add it to 29, then carry on: 296 / 638

On to step 3:
When dividing 296 by 638, we get 0 with a remainder of 296.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 296, we end up with 296.
Append the next digit (9) from the dividend to 296 and continue with: 2969 / 638

Going ahead to step 4:
If we divide 2969 by 638, we get 4 and a remainder of 417.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 2552 away from 2969, we end up with 417.
Take the next digit (8) from the dividend and append it to 417, then repeat: 4178 / 638

Moving on to step 5:
4178 divided by 638 is 6 with a remainder of 350.
Write down 6 as next digit of the result. 
Result so far: 46.0
If we subtract 3828 from 4178, we get 350.
Fetch the next digit (5) from the dividend, attach it to 350 and continue: 3505 / 638

Advancing to step 6:
The number 638 fits into 3505 5 times, leaving a remainder of 315.
Record the quotient 5 as the next digit in the result. 
Result so far: 465.0
Deduct 3190 from 3505 and we're left with 315.
Grab the next digit (9) from the dividend, add it to 315, then carry on: 3159 / 638

Advancing to step 7:
638 can be fit into 3159 4 times, resulting in a remainder of 607.
The number 4 becomes the next digit in our result. 
Result so far: 4654.0
Subtract 2552 from 3159 to get 607.
Grab the next digit (0) from the dividend, add it to 607, then carry on: 6070 / 638

Advancing to step 8:
638 goes into 6070 9 times with a remainder of 328.
The next digit of our result is 9. 
Result so far: 46549.0
If we take 5742 away from 6070, we end up with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Moving on to step 9:
The number 638 fits into 3280 5 times, leaving a remainder of 90.
The next digit of our result is 5. 
Result so far: 46549.5
The remainder is 90 after subtracting 3190 from 3280.
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 10:
When dividing 900 by 638, we get 1 with a remainder of 262.
Use 1 as the next digit of our solution. 
Result so far: 46549.51
Subtract 638 from 900 to get 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Moving on to step 11:
638 can be fit into 2620 4 times, resulting in a remainder of 68.
Use 4 as the next digit of our solution. 
Result so far: 46549.514
Deduct 2552 from 2620 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 12:
638 goes into 680 1 times with a remainder of 42.
The next digit of our result is 1. 
Result so far: 46549.5141
Deduct 638 from 680 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 13:
420 divided by 638 is 0 with a remainder of 420.
Write down 0 as next digit of the result. 
Result so far: 46549.5141
The remainder is 420 after subtracting 0 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Moving on to step 14:
If we divide 4200 by 638, we get 6 and a remainder of 372.
The number 6 becomes the next digit in our result. 
Result so far: 46549.514106
Deduct 3828 from 4200 and we're left with 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Going ahead to step 15:
638 can be fit into 3720 5 times, resulting in a remainder of 530.
Write down 5 as next digit of the result. 
Result so far: 46549.5141065
If we subtract 3190 from 3720, we get 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

Advancing to step 16:
If we divide 5300 by 638, we get 8 and a remainder of 196.
Write down 8 as next digit of the result. 
Result so far: 46549.51410658
Subtracting 5104 from 5300 leaves us with 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

After the division, we end up with 46549.51410658 and a remainder of 1.96e-07.
