49703510 ÷ 407 
The aim is to understand the frequency of 407 in 49703510.

Let's proceed to step 1:
407 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (9) from the dividend and append it to 4, then repeat: 49 / 407

Going ahead to step 2:
The number 407 fits into 49 0 times, leaving a remainder of 49.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 49, we get 49.
Append the next digit (7) from the dividend to 49 and continue with: 497 / 407

Let's proceed to step 3:
497 divided by 407 is 1 with a remainder of 90.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 407 from 497, we get 90.
Take the next digit (0) from the dividend and append it to 90, then repeat: 900 / 407

Let's proceed to step 4:
407 can be fit into 900 2 times, resulting in a remainder of 86.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
The remainder is 86 after subtracting 814 from 900.
Grab the next digit (3) from the dividend, add it to 86, then carry on: 863 / 407

On to step 5:
If we divide 863 by 407, we get 2 and a remainder of 49.
Use 2 as the next digit of our solution. 
Result so far: 122.0
If we take 814 away from 863, we end up with 49.
Include the next digit (5) from the dividend after 49, then repeat: 495 / 407

Going ahead to step 6:
407 goes into 495 1 times with a remainder of 88.
Put 1 as the next digit of the answer. 
Result so far: 1221.0
Subtract 407 from 495 to get 88.
Fetch the next digit (1) from the dividend, attach it to 88 and continue: 881 / 407

Moving on to step 7:
407 goes into 881 2 times with a remainder of 67.
Write down 2 as next digit of the result. 
Result so far: 12212.0
The remainder is 67 after subtracting 814 from 881.
Take the next digit (0) from the dividend and append it to 67, then repeat: 670 / 407

Going ahead to step 8:
670 divided by 407 is 1 with a remainder of 263.
Use 1 as the next digit of our solution. 
Result so far: 122121.0
If we subtract 407 from 670, we get 263.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2630, and continue the process.

Going ahead to step 9:
407 can be fit into 2630 6 times, resulting in a remainder of 188.
The next digit of our result is 6. 
Result so far: 122121.6
If we take 2442 away from 2630, we end up with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Advancing to step 10:
If we divide 1880 by 407, we get 4 and a remainder of 252.
The number 4 becomes the next digit in our result. 
Result so far: 122121.64
If we take 1628 away from 1880, we end up with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Moving on to step 11:
When dividing 2520 by 407, we get 6 with a remainder of 78.
Put 6 as the next digit of the answer. 
Result so far: 122121.646
The remainder is 78 after subtracting 2442 from 2520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Advancing to step 12:
780 divided by 407 is 1 with a remainder of 373.
Use 1 as the next digit of our solution. 
Result so far: 122121.6461
Subtracting 407 from 780 leaves us with 373.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3730, and continue the process.

Let's proceed to step 13:
The number 407 fits into 3730 9 times, leaving a remainder of 67.
Record the quotient 9 as the next digit in the result. 
Result so far: 122121.64619
If we subtract 3663 from 3730, we get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Let's proceed to step 14:
407 goes into 670 1 times with a remainder of 263.
Record the quotient 1 as the next digit in the result. 
Result so far: 122121.646191
Subtract 407 from 670 to get 263.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2630, and continue the process.

Advancing to step 15:
When dividing 2630 by 407, we get 6 with a remainder of 188.
Record the quotient 6 as the next digit in the result. 
Result so far: 122121.6461916
Subtract 2442 from 2630 to get 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Moving on to step 16:
407 can be fit into 1880 4 times, resulting in a remainder of 252.
Record the quotient 4 as the next digit in the result. 
Result so far: 122121.64619164
The remainder is 252 after subtracting 1628 from 1880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

After the division, we end up with 122121.64619164 and a remainder of 2.52e-07.
