We look at the division of 63857806 by 377 
Our goal is to divide 63857806 by 377.

On to step 1:
377 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 377

Advancing to step 2:
377 goes into 63 0 times with a remainder of 63.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 63 to get 63.
Bring next digit (8) of the dividend behind the 63 and repeat the process: 638 / 377

Advancing to step 3:
377 can be fit into 638 1 times, resulting in a remainder of 261.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 377 away from 638, we end up with 261.
Bring next digit (5) of the dividend behind the 261 and repeat the process: 2615 / 377

Step 4:
2615 divided by 377 is 6 with a remainder of 353.
The next digit of our result is 6. 
Result so far: 16.0
Subtract 2262 from 2615 to get 353.
Fetch the next digit (7) from the dividend, attach it to 353 and continue: 3537 / 377

Step 5:
When dividing 3537 by 377, we get 9 with a remainder of 144.
The next digit of our result is 9. 
Result so far: 169.0
The remainder is 144 after subtracting 3393 from 3537.
Take the next digit (8) from the dividend and append it to 144, then repeat: 1448 / 377

Advancing to step 6:
If we divide 1448 by 377, we get 3 and a remainder of 317.
Write down 3 as next digit of the result. 
Result so far: 1693.0
Subtracting 1131 from 1448 leaves us with 317.
Fetch the next digit (0) from the dividend, attach it to 317 and continue: 3170 / 377

Let's proceed to step 7:
When dividing 3170 by 377, we get 8 with a remainder of 154.
The number 8 becomes the next digit in our result. 
Result so far: 16938.0
Subtracting 3016 from 3170 leaves us with 154.
Grab the next digit (6) from the dividend, add it to 154, then carry on: 1546 / 377

Let's proceed to step 8:
1546 divided by 377 is 4 with a remainder of 38.
The number 4 becomes the next digit in our result. 
Result so far: 169384.0
The remainder is 38 after subtracting 1508 from 1546.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 9:
377 goes into 380 1 times with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 169384.1
Deduct 377 from 380 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 10:
If we divide 30 by 377, we get 0 and a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 169384.1
Subtracting 0 from 30 leaves us 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.

Going ahead to step 11:
300 divided by 377 is 0 with a remainder of 300.
Record the quotient 0 as the next digit in the result. 
Result so far: 169384.1
If we subtract 0 from 300, we get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

The final outcome is 169384.1, with a leftover of 0.03.
