We look at the division of 63992377 by 438 
Our goal is to divide 63992377 by 438.

Advancing to step 1:
438 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 438

Step 2:
The number 438 fits into 63 0 times, leaving a remainder of 63.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 63 and we're left with 63.
Take the next digit (9) from the dividend and append it to 63, then repeat: 639 / 438

Moving on to step 3:
438 can be fit into 639 1 times, resulting in a remainder of 201.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 438 from 639 to get 201.
Take the next digit (9) from the dividend and append it to 201, then repeat: 2019 / 438

Let's proceed to step 4:
2019 divided by 438 is 4 with a remainder of 267.
Put 4 as the next digit of the answer. 
Result so far: 14.0
Subtracting 1752 from 2019 leaves us with 267.
Include the next digit (2) from the dividend after 267, then repeat: 2672 / 438

Step 5:
The number 438 fits into 2672 6 times, leaving a remainder of 44.
The next digit of our result is 6. 
Result so far: 146.0
Subtract 2628 from 2672 to get 44.
Bring next digit (3) of the dividend behind the 44 and repeat the process: 443 / 438

On to step 6:
If we divide 443 by 438, we get 1 and a remainder of 5.
The next digit of our result is 1. 
Result so far: 1461.0
If we take 438 away from 443, we end up with 5.
Bring next digit (7) of the dividend behind the 5 and repeat the process: 57 / 438

Moving on to step 7:
When dividing 57 by 438, we get 0 with a remainder of 57.
Put 0 as the next digit of the answer. 
Result so far: 14610.0
Subtracting 0 from 57 leaves us with 57.
Append the next digit (7) from the dividend to 57 and continue with: 577 / 438

On to step 8:
The number 438 fits into 577 1 times, leaving a remainder of 139.
The number 1 becomes the next digit in our result. 
Result so far: 146101.0
If we subtract 438 from 577, we get 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

Step 9:
If we divide 1390 by 438, we get 3 and a remainder of 76.
Use 3 as the next digit of our solution. 
Result so far: 146101.3
Subtracting 1314 from 1390 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 10:
438 can be fit into 760 1 times, resulting in a remainder of 322.
Write down 1 as next digit of the result. 
Result so far: 146101.31
If we take 438 away from 760, we end up 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.

Step 11:
438 goes into 3220 7 times with a remainder of 154.
Put 7 as the next digit of the answer. 
Result so far: 146101.317
If we subtract 3066 from 3220, we get 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

On to step 12:
1540 divided by 438 is 3 with a remainder of 226.
The number 3 becomes the next digit in our result. 
Result so far: 146101.3173
If we take 1314 away from 1540, we end up with 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Advancing to step 13:
438 goes into 2260 5 times with a remainder of 70.
Write down 5 as next digit of the result. 
Result so far: 146101.31735
If we take 2190 away from 2260, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 14:
The number 438 fits into 700 1 times, leaving a remainder of 262.
The next digit of our result is 1. 
Result so far: 146101.317351
If we take 438 away from 700, we end up with 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Let's proceed to step 15:
2620 divided by 438 is 5 with a remainder of 430.
Record the quotient 5 as the next digit in the result. 
Result so far: 146101.3173515
If we subtract 2190 from 2620, we get 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Advancing to step 16:
4300 divided by 438 is 9 with a remainder of 358.
Write down 9 as next digit of the result. 
Result so far: 146101.31735159
Deduct 3942 from 4300 and we're left with 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

The quotient of the division is 146101.31735159, and the remainder is 3.58e-07.
