64129832 ÷ 407 
Our goal is to divide 64129832 by 407.

On to step 1:
6 divided by 407 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 407

Step 2:
When dividing 64 by 407, we get 0 with a remainder of 64.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 64 leaves us with 64.
Fetch the next digit (1) from the dividend, attach it to 64 and continue: 641 / 407

Let's proceed to step 3:
407 can be fit into 641 1 times, resulting in a remainder of 234.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 407 from 641 and we're left with 234.
Fetch the next digit (2) from the dividend, attach it to 234 and continue: 2342 / 407

Moving on to step 4:
When dividing 2342 by 407, we get 5 with a remainder of 307.
Write down 5 as next digit of the result. 
Result so far: 15.0
If we take 2035 away from 2342, we end up with 307.
Take the next digit (9) from the dividend and append it to 307, then repeat: 3079 / 407

Let's proceed to step 5:
407 goes into 3079 7 times with a remainder of 230.
The next digit of our result is 7. 
Result so far: 157.0
Subtract 2849 from 3079 to get 230.
Bring next digit (8) of the dividend behind the 230 and repeat the process: 2308 / 407

Let's proceed to step 6:
The number 407 fits into 2308 5 times, leaving a remainder of 273.
Record the quotient 5 as the next digit in the result. 
Result so far: 1575.0
Subtracting 2035 from 2308 leaves us with 273.
Append the next digit (3) from the dividend to 273 and continue with: 2733 / 407

Advancing to step 7:
If we divide 2733 by 407, we get 6 and a remainder of 291.
Put 6 as the next digit of the answer. 
Result so far: 15756.0
The remainder is 291 after subtracting 2442 from 2733.
Append the next digit (2) from the dividend to 291 and continue with: 2912 / 407

Step 8:
407 goes into 2912 7 times with a remainder of 63.
Record the quotient 7 as the next digit in the result. 
Result so far: 157567.0
Deduct 2849 from 2912 and we're left with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Moving on to step 9:
407 can be fit into 630 1 times, resulting in a remainder of 223.
Use 1 as the next digit of our solution. 
Result so far: 157567.1
Subtract 407 from 630 to get 223.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2230, and continue the process.

Advancing to step 10:
When dividing 2230 by 407, we get 5 with a remainder of 195.
Record the quotient 5 as the next digit in the result. 
Result so far: 157567.15
Subtracting 2035 from 2230 leaves us with 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

On to step 11:
The number 407 fits into 1950 4 times, leaving a remainder of 322.
Put 4 as the next digit of the answer. 
Result so far: 157567.154
Subtracting 1628 from 1950 leaves us with 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

On to step 12:
407 can be fit into 3220 7 times, resulting in a remainder of 371.
Write down 7 as next digit of the result. 
Result so far: 157567.1547
The remainder is 371 after subtracting 2849 from 3220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3710, and continue the process.

Advancing to step 13:
407 goes into 3710 9 times with a remainder of 47.
The number 9 becomes the next digit in our result. 
Result so far: 157567.15479
Deduct 3663 from 3710 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Step 14:
407 goes into 470 1 times with a remainder of 63.
The next digit of our result is 1. 
Result so far: 157567.154791
The remainder is 63 after subtracting 407 from 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Step 15:
When dividing 630 by 407, we get 1 with a remainder of 223.
The number 1 becomes the next digit in our result. 
Result so far: 157567.1547911
The remainder is 223 after subtracting 407 from 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2230, and continue the process.

After the division, we end up with 157567.1547911 and a remainder of 2.23e-06.
