We look at the division of 4371520 by 657 
We want to figure out the number of times 4371520 can be divided by 657.

On to step 1:
When dividing 4 by 657, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 657

Advancing to step 2:
43 divided by 657 is 0 with a remainder of 43.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 43 after subtracting 0 from 43.
Bring next digit (7) of the dividend behind the 43 and repeat the process: 437 / 657

Moving on to step 3:
437 divided by 657 is 0 with a remainder of 437.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 437 leaves us with 437.
Take the next digit (1) from the dividend and append it to 437, then repeat: 4371 / 657

Step 4:
When dividing 4371 by 657, we get 6 with a remainder of 429.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we subtract 3942 from 4371, we get 429.
Append the next digit (5) from the dividend to 429 and continue with: 4295 / 657

Let's proceed to step 5:
657 goes into 4295 6 times with a remainder of 353.
The number 6 becomes the next digit in our result. 
Result so far: 66.0
If we subtract 3942 from 4295, we get 353.
Include the next digit (2) from the dividend after 353, then repeat: 3532 / 657

On to step 6:
657 can be fit into 3532 5 times, resulting in a remainder of 247.
Use 5 as the next digit of our solution. 
Result so far: 665.0
Subtract 3285 from 3532 to get 247.
Fetch the next digit (0) from the dividend, attach it to 247 and continue: 2470 / 657

Step 7:
2470 divided by 657 is 3 with a remainder of 499.
Use 3 as the next digit of our solution. 
Result so far: 6653.0
The remainder is 499 after subtracting 1971 from 2470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4990, and continue the process.

Advancing to step 8:
657 can be fit into 4990 7 times, resulting in a remainder of 391.
The number 7 becomes the next digit in our result. 
Result so far: 6653.7
Subtracting 4599 from 4990 leaves us with 391.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3910, and continue the process.

Moving on to step 9:
657 can be fit into 3910 5 times, resulting in a remainder of 625.
Write down 5 as next digit of the result. 
Result so far: 6653.75
Deduct 3285 from 3910 and we're left with 625.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6250, and continue the process.

Advancing to step 10:
657 goes into 6250 9 times with a remainder of 337.
Write down 9 as next digit of the result. 
Result so far: 6653.759
If we subtract 5913 from 6250, we get 337.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3370, and continue the process.

On to step 11:
When dividing 3370 by 657, we get 5 with a remainder of 85.
The number 5 becomes the next digit in our result. 
Result so far: 6653.7595
If we take 3285 away from 3370, we end up with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Moving on to step 12:
657 can be fit into 850 1 times, resulting in a remainder of 193.
The number 1 becomes the next digit in our result. 
Result so far: 6653.75951
If we subtract 657 from 850, we get 193.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

On to step 13:
If we divide 1930 by 657, we get 2 and a remainder of 616.
Put 2 as the next digit of the answer. 
Result so far: 6653.759512
If we subtract 1314 from 1930, we get 616.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6160, and continue the process.

On to step 14:
657 goes into 6160 9 times with a remainder of 247.
Use 9 as the next digit of our solution. 
Result so far: 6653.7595129
Subtracting 5913 from 6160 leaves us with 247.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

Let's proceed to step 15:
If we divide 2470 by 657, we get 3 and a remainder of 499.
The number 3 becomes the next digit in our result. 
Result so far: 6653.75951293
Subtracting 1971 from 2470 leaves us with 499.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4990, and continue the process.

The final outcome is 6653.75951293, with a leftover of 4.99e-07.
