We're dividing 71147958 by 407 
The aim is to understand the frequency of 407 in 71147958.

On to step 1:
When dividing 7 by 407, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 407

On to step 2:
407 goes into 71 0 times with a remainder of 71.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 71 and we're left with 71.
Include the next digit (1) from the dividend after 71, then repeat: 711 / 407

Let's proceed to step 3:
407 can be fit into 711 1 times, resulting in a remainder of 304.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 407 from 711 to get 304.
Fetch the next digit (4) from the dividend, attach it to 304 and continue: 3044 / 407

Step 4:
407 can be fit into 3044 7 times, resulting in a remainder of 195.
Write down 7 as next digit of the result. 
Result so far: 17.0
Deduct 2849 from 3044 and we're left with 195.
Take the next digit (7) from the dividend and append it to 195, then repeat: 1957 / 407

On to step 5:
407 can be fit into 1957 4 times, resulting in a remainder of 329.
Write down 4 as next digit of the result. 
Result so far: 174.0
Subtracting 1628 from 1957 leaves us with 329.
Take the next digit (9) from the dividend and append it to 329, then repeat: 3299 / 407

Let's proceed to step 6:
407 can be fit into 3299 8 times, resulting in a remainder of 43.
The number 8 becomes the next digit in our result. 
Result so far: 1748.0
Subtracting 3256 from 3299 leaves us with 43.
Take the next digit (5) from the dividend and append it to 43, then repeat: 435 / 407

Let's proceed to step 7:
407 goes into 435 1 times with a remainder of 28.
The next digit of our result is 1. 
Result so far: 17481.0
Subtract 407 from 435 to get 28.
Grab the next digit (8) from the dividend, add it to 28, then carry on: 288 / 407

On to step 8:
407 goes into 288 0 times with a remainder of 288.
Put 0 as the next digit of the answer. 
Result so far: 174810.0
If we take 0 away from 288, we end up with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

On to step 9:
2880 divided by 407 is 7 with a remainder of 31.
The number 7 becomes the next digit in our result. 
Result so far: 174810.7
Subtract 2849 from 2880 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 10:
407 can be fit into 310 0 times, resulting in a remainder of 310.
Use 0 as the next digit of our solution. 
Result so far: 174810.7
If we take 0 away from 310, we end up with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Advancing to step 11:
407 can be fit into 3100 7 times, resulting in a remainder of 251.
The next digit of our result is 7. 
Result so far: 174810.707
If we take 2849 away from 3100, we end up with 251.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2510, and continue the process.

Let's proceed to step 12:
2510 divided by 407 is 6 with a remainder of 68.
Use 6 as the next digit of our solution. 
Result so far: 174810.7076
Subtracting 2442 from 2510 leaves us 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.

Step 13:
The number 407 fits into 680 1 times, leaving a remainder of 273.
Put 1 as the next digit of the answer. 
Result so far: 174810.70761
Subtracting 407 from 680 leaves us with 273.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2730, and continue the process.

Moving on to step 14:
If we divide 2730 by 407, we get 6 and a remainder of 288.
Use 6 as the next digit of our solution. 
Result so far: 174810.707616
The remainder is 288 after subtracting 2442 from 2730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Advancing to step 15:
The number 407 fits into 2880 7 times, leaving a remainder of 31.
Record the quotient 7 as the next digit in the result. 
Result so far: 174810.7076167
Deduct 2849 from 2880 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 16:
310 divided by 407 is 0 with a remainder of 310.
The number 0 becomes the next digit in our result. 
Result so far: 174810.7076167
Deduct 0 from 310 and we're left with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

The quotient of the division is 174810.7076167, and the remainder is 3.1e-07.
