80057521 ÷ 406 
We want to figure out the number of times 80057521 can be divided by 406.

Advancing to step 1:
The number 406 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 406

Step 2:
406 can be fit into 80 0 times, resulting in a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 80 and we're left with 80.
Include the next digit (0) from the dividend after 80, then repeat: 800 / 406

Advancing to step 3:
406 can be fit into 800 1 times, resulting in a remainder of 394.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 406 from 800 to get 394.
Fetch the next digit (5) from the dividend, attach it to 394 and continue: 3945 / 406

Advancing to step 4:
When dividing 3945 by 406, we get 9 with a remainder of 291.
Use 9 as the next digit of our solution. 
Result so far: 19.0
Subtract 3654 from 3945 to get 291.
Take the next digit (7) from the dividend and append it to 291, then repeat: 2917 / 406

On to step 5:
When dividing 2917 by 406, we get 7 with a remainder of 75.
Write down 7 as next digit of the result. 
Result so far: 197.0
If we subtract 2842 from 2917, we get 75.
Take the next digit (5) from the dividend and append it to 75, then repeat: 755 / 406

Step 6:
755 divided by 406 is 1 with a remainder of 349.
The next digit of our result is 1. 
Result so far: 1971.0
If we subtract 406 from 755, we get 349.
Take the next digit (2) from the dividend and append it to 349, then repeat: 3492 / 406

On to step 7:
When dividing 3492 by 406, we get 8 with a remainder of 244.
Use 8 as the next digit of our solution. 
Result so far: 19718.0
The remainder is 244 after subtracting 3248 from 3492.
Include the next digit (1) from the dividend after 244, then repeat: 2441 / 406

Moving on to step 8:
The number 406 fits into 2441 6 times, leaving a remainder of 5.
The next digit of our result is 6. 
Result so far: 197186.0
Subtracting 2436 from 2441 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 9:
When dividing 50 by 406, we get 0 with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 197186.0
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 10:
500 divided by 406 is 1 with a remainder of 94.
The next digit of our result is 1. 
Result so far: 197186.01
If we take 406 away from 500, we end up with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

On to step 11:
When dividing 940 by 406, we get 2 with a remainder of 128.
Use 2 as the next digit of our solution. 
Result so far: 197186.012
Deduct 812 from 940 and we're left with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

On to step 12:
1280 divided by 406 is 3 with a remainder of 62.
Record the quotient 3 as the next digit in the result. 
Result so far: 197186.0123
Deduct 1218 from 1280 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 13:
406 goes into 620 1 times with a remainder of 214.
The next digit of our result is 1. 
Result so far: 197186.01231
Subtracting 406 from 620 leaves us with 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Going ahead to step 14:
406 can be fit into 2140 5 times, resulting in a remainder of 110.
The number 5 becomes the next digit in our result. 
Result so far: 197186.012315
Deduct 2030 from 2140 and we're left with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Advancing to step 15:
406 goes into 1100 2 times with a remainder of 288.
The number 2 becomes the next digit in our result. 
Result so far: 197186.0123152
Subtract 812 from 1100 to get 288.
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 16:
406 can be fit into 2880 7 times, resulting in a remainder of 38.
Write down 7 as next digit of the result. 
Result so far: 197186.01231527
Subtract 2842 from 2880 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

The final outcome is 197186.01231527, with a leftover of 3.8e-08.
