63773712 divided by 415 
We want to figure out the number of times 63773712 can be divided by 415.

On to step 1:
When dividing 6 by 415, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 415

Step 2:
415 goes into 63 0 times with a remainder of 63.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 63, we end up with 63.
Fetch the next digit (7) from the dividend, attach it to 63 and continue: 637 / 415

Moving on to step 3:
415 goes into 637 1 times with a remainder of 222.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 415 from 637 to get 222.
Bring next digit (7) of the dividend behind the 222 and repeat the process: 2227 / 415

Advancing to step 4:
When dividing 2227 by 415, we get 5 with a remainder of 152.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Subtracting 2075 from 2227 leaves us with 152.
Append the next digit (3) from the dividend to 152 and continue with: 1523 / 415

Moving on to step 5:
1523 divided by 415 is 3 with a remainder of 278.
The number 3 becomes the next digit in our result. 
Result so far: 153.0
Subtracting 1245 from 1523 leaves us with 278.
Grab the next digit (7) from the dividend, add it to 278, then carry on: 2787 / 415

On to step 6:
2787 divided by 415 is 6 with a remainder of 297.
Write down 6 as next digit of the result. 
Result so far: 1536.0
The remainder is 297 after subtracting 2490 from 2787.
Fetch the next digit (1) from the dividend, attach it to 297 and continue: 2971 / 415

Step 7:
2971 divided by 415 is 7 with a remainder of 66.
Use 7 as the next digit of our solution. 
Result so far: 15367.0
Subtracting 2905 from 2971 leaves us with 66.
Bring next digit (2) of the dividend behind the 66 and repeat the process: 662 / 415

Going ahead to step 8:
When dividing 662 by 415, we get 1 with a remainder of 247.
Use 1 as the next digit of our solution. 
Result so far: 153671.0
Deduct 415 from 662 and we're left 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.

On to step 9:
415 goes into 2470 5 times with a remainder of 395.
Record the quotient 5 as the next digit in the result. 
Result so far: 153671.5
Subtracting 2075 from 2470 leaves us with 395.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3950, and continue the process.

Advancing to step 10:
When dividing 3950 by 415, we get 9 with a remainder of 215.
The number 9 becomes the next digit in our result. 
Result so far: 153671.59
The remainder is 215 after subtracting 3735 from 3950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Let's proceed to step 11:
2150 divided by 415 is 5 with a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 153671.595
Subtracting 2075 from 2150 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

On to step 12:
If we divide 750 by 415, we get 1 and a remainder of 335.
Record the quotient 1 as the next digit in the result. 
Result so far: 153671.5951
The remainder is 335 after subtracting 415 from 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

Step 13:
415 can be fit into 3350 8 times, resulting in a remainder of 30.
The number 8 becomes the next digit in our result. 
Result so far: 153671.59518
If we take 3320 away from 3350, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 14:
300 divided by 415 is 0 with a remainder of 300.
The number 0 becomes the next digit in our result. 
Result so far: 153671.59518
The remainder is 300 after subtracting 0 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Advancing to step 15:
3000 divided by 415 is 7 with a remainder of 95.
The number 7 becomes the next digit in our result. 
Result so far: 153671.5951807
Subtracting 2905 from 3000 leaves us with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

On to step 16:
The number 415 fits into 950 2 times, leaving a remainder of 120.
Put 2 as the next digit of the answer. 
Result so far: 153671.59518072
Deduct 830 from 950 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

In conclusion, the division gives 153671.59518072 with a balance of 1.2e-07.
