63339491 ÷ 507 
We want to divide 63339491 by 507.

Going ahead to step 1:
6 divided by 507 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 507

Let's proceed to step 2:
If we divide 63 by 507, we get 0 and 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.
Include the next digit (3) from the dividend after 63, then repeat: 633 / 507

Moving on to step 3:
When dividing 633 by 507, we get 1 with a remainder of 126.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 507 from 633, we get 126.
Append the next digit (3) from the dividend to 126 and continue with: 1263 / 507

On to step 4:
The number 507 fits into 1263 2 times, leaving a remainder of 249.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we take 1014 away from 1263, we end up with 249.
Fetch the next digit (9) from the dividend, attach it to 249 and continue: 2499 / 507

On to step 5:
2499 divided by 507 is 4 with a remainder of 471.
The number 4 becomes the next digit in our result. 
Result so far: 124.0
If we take 2028 away from 2499, we end up with 471.
Take the next digit (4) from the dividend and append it to 471, then repeat: 4714 / 507

Let's proceed to step 6:
507 can be fit into 4714 9 times, resulting in a remainder of 151.
The number 9 becomes the next digit in our result. 
Result so far: 1249.0
Deduct 4563 from 4714 and we're left with 151.
Grab the next digit (9) from the dividend, add it to 151, then carry on: 1519 / 507

Let's proceed to step 7:
507 can be fit into 1519 2 times, resulting in a remainder of 505.
The number 2 becomes the next digit in our result. 
Result so far: 12492.0
Subtract 1014 from 1519 to get 505.
Grab the next digit (1) from the dividend, add it to 505, then carry on: 5051 / 507

Going ahead to step 8:
If we divide 5051 by 507, we get 9 and a remainder of 488.
Put 9 as the next digit of the answer. 
Result so far: 124929.0
Subtract 4563 from 5051 to get 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

Advancing to step 9:
If we divide 4880 by 507, we get 9 and a remainder of 317.
Record the quotient 9 as the next digit in the result. 
Result so far: 124929.9
Subtract 4563 from 4880 to get 317.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3170, and continue the process.

Moving on to step 10:
When dividing 3170 by 507, we get 6 with a remainder of 128.
The number 6 becomes the next digit in our result. 
Result so far: 124929.96
If we subtract 3042 from 3170, we get 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 11:
If we divide 1280 by 507, we get 2 and a remainder of 266.
The next digit of our result is 2. 
Result so far: 124929.962
If we take 1014 away from 1280, we end up with 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Going ahead to step 12:
If we divide 2660 by 507, we get 5 and a remainder of 125.
Write down 5 as next digit of the result. 
Result so far: 124929.9625
The remainder is 125 after subtracting 2535 from 2660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

On to step 13:
When dividing 1250 by 507, we get 2 with a remainder of 236.
The number 2 becomes the next digit in our result. 
Result so far: 124929.96252
Subtract 1014 from 1250 to get 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Advancing to step 14:
When dividing 2360 by 507, we get 4 with a remainder of 332.
Use 4 as the next digit of our solution. 
Result so far: 124929.962524
Deduct 2028 from 2360 and we're left with 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

Advancing to step 15:
507 goes into 3320 6 times with a remainder of 278.
The next digit of our result is 6. 
Result so far: 124929.9625246
If we take 3042 away from 3320, we end up with 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

Advancing to step 16:
When dividing 2780 by 507, we get 5 with a remainder of 245.
The next digit of our result is 5. 
Result so far: 124929.96252465
If we take 2535 away from 2780, we end up with 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

The final outcome is 124929.96252465, with a leftover of 2.45e-07.
