38764633 ÷ 428 
Our goal is to divide 38764633 by 428.

Step 1:
428 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 428

Going ahead to step 2:
428 can be fit into 38 0 times, resulting in a remainder of 38.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 38, we get 38.
Bring next digit (7) of the dividend behind the 38 and repeat the process: 387 / 428

Let's proceed to step 3:
428 can be fit into 387 0 times, resulting in a remainder of 387.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 387 leaves us with 387.
Grab the next digit (6) from the dividend, add it to 387, then carry on: 3876 / 428

Advancing to step 4:
If we divide 3876 by 428, we get 9 and a remainder of 24.
The next digit of our result is 9. 
Result so far: 9.0
If we take 3852 away from 3876, we end up with 24.
Bring next digit (4) of the dividend behind the 24 and repeat the process: 244 / 428

Step 5:
When dividing 244 by 428, we get 0 with a remainder of 244.
Record the quotient 0 as the next digit in the result. 
Result so far: 90.0
Deduct 0 from 244 and we're left with 244.
Take the next digit (6) from the dividend and append it to 244, then repeat: 2446 / 428

Advancing to step 6:
2446 divided by 428 is 5 with a remainder of 306.
Use 5 as the next digit of our solution. 
Result so far: 905.0
If we take 2140 away from 2446, we end up with 306.
Fetch the next digit (3) from the dividend, attach it to 306 and continue: 3063 / 428

Let's proceed to step 7:
428 can be fit into 3063 7 times, resulting in a remainder of 67.
Write down 7 as next digit of the result. 
Result so far: 9057.0
If we take 2996 away from 3063, we end up with 67.
Take the next digit (3) from the dividend and append it to 67, then repeat: 673 / 428

Step 8:
673 divided by 428 is 1 with a remainder of 245.
Record the quotient 1 as the next digit in the result. 
Result so far: 90571.0
The remainder is 245 after subtracting 428 from 673.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Step 9:
2450 divided by 428 is 5 with a remainder of 310.
Put 5 as the next digit of the answer. 
Result so far: 90571.5
If we subtract 2140 from 2450, we get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Let's proceed to step 10:
428 goes into 3100 7 times with a remainder of 104.
Use 7 as the next digit of our solution. 
Result so far: 90571.57
If we take 2996 away from 3100, we end up with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

On to step 11:
428 goes into 1040 2 times with a remainder of 184.
Write down 2 as next digit of the result. 
Result so far: 90571.572
Subtract 856 from 1040 to get 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Step 12:
428 goes into 1840 4 times with a remainder of 128.
The next digit of our result is 4. 
Result so far: 90571.5724
Subtract 1712 from 1840 to 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.

Step 13:
When dividing 1280 by 428, we get 2 with a remainder of 424.
Record the quotient 2 as the next digit in the result. 
Result so far: 90571.57242
If we subtract 856 from 1280, we get 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

Advancing to step 14:
428 can be fit into 4240 9 times, resulting in a remainder of 388.
The next digit of our result is 9. 
Result so far: 90571.572429
If we subtract 3852 from 4240, we get 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Step 15:
428 goes into 3880 9 times with a remainder of 28.
The number 9 becomes the next digit in our result. 
Result so far: 90571.5724299
Deduct 3852 from 3880 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The final outcome is 90571.5724299, with a leftover of 2.8e-07.
