We look at the division of 38115679 by 421 
We want to divide 38115679 by 421.

On to step 1:
421 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 421

Going ahead to step 2:
421 goes into 38 0 times with a remainder of 38.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 38 leaves us with 38.
Include the next digit (1) from the dividend after 38, then repeat: 381 / 421

Step 3:
When dividing 381 by 421, we get 0 with a remainder of 381.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 381 after subtracting 0 from 381.
Bring next digit (1) of the dividend behind the 381 and repeat the process: 3811 / 421

Going ahead to step 4:
421 goes into 3811 9 times with a remainder of 22.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
The remainder is 22 after subtracting 3789 from 3811.
Bring next digit (5) of the dividend behind the 22 and repeat the process: 225 / 421

Let's proceed to step 5:
225 divided by 421 is 0 with a remainder of 225.
Record the quotient 0 as the next digit in the result. 
Result so far: 90.0
Subtract 0 from 225 to get 225.
Fetch the next digit (6) from the dividend, attach it to 225 and continue: 2256 / 421

Moving on to step 6:
When dividing 2256 by 421, we get 5 with a remainder of 151.
The next digit of our result is 5. 
Result so far: 905.0
Subtracting 2105 from 2256 leaves us with 151.
Take the next digit (7) from the dividend and append it to 151, then repeat: 1517 / 421

Step 7:
421 can be fit into 1517 3 times, resulting in a remainder of 254.
Record the quotient 3 as the next digit in the result. 
Result so far: 9053.0
Deduct 1263 from 1517 and we're left with 254.
Fetch the next digit (9) from the dividend, attach it to 254 and continue: 2549 / 421

Let's proceed to step 8:
The number 421 fits into 2549 6 times, leaving a remainder of 23.
Record the quotient 6 as the next digit in the result. 
Result so far: 90536.0
If we take 2526 away from 2549, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 9:
421 goes into 230 0 times with a remainder of 230.
Record the quotient 0 as the next digit in the result. 
Result so far: 90536.0
If we take 0 away from 230, we end up with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Step 10:
421 can be fit into 2300 5 times, resulting in a remainder of 195.
Put 5 as the next digit of the answer. 
Result so far: 90536.05
Deduct 2105 from 2300 and we're left with 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Moving on to step 11:
421 goes into 1950 4 times with a remainder of 266.
Put 4 as the next digit of the answer. 
Result so far: 90536.054
Subtracting 1684 from 1950 leaves us 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 421, we get 6 and a remainder of 134.
Record the quotient 6 as the next digit in the result. 
Result so far: 90536.0546
The remainder is 134 after subtracting 2526 from 2660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

On to step 13:
1340 divided by 421 is 3 with a remainder of 77.
The number 3 becomes the next digit in our result. 
Result so far: 90536.05463
Deduct 1263 from 1340 and we're left with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Moving on to step 14:
421 can be fit into 770 1 times, resulting in a remainder of 349.
Record the quotient 1 as the next digit in the result. 
Result so far: 90536.054631
Deduct 421 from 770 and we're left with 349.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3490, and continue the process.

Advancing to step 15:
The number 421 fits into 3490 8 times, leaving a remainder of 122.
Put 8 as the next digit of the answer. 
Result so far: 90536.0546318
Subtracting 3368 from 3490 leaves us with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

On to step 16:
The number 421 fits into 1220 2 times, leaving a remainder of 378.
Put 2 as the next digit of the answer. 
Result so far: 90536.05463182
Subtracting 842 from 1220 leaves us with 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

The final outcome is 90536.05463182, with a leftover of 3.78e-07.
