We're dividing 39337778 by 421 
We want to divide 39337778 by 421.

Moving on to step 1:
421 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 421

Let's proceed to step 2:
421 goes into 39 0 times with a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Bring next digit (3) of the dividend behind the 39 and repeat the process: 393 / 421

Going ahead to step 3:
421 goes into 393 0 times with a remainder of 393.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 393 to get 393.
Grab the next digit (3) from the dividend, add it to 393, then carry on: 3933 / 421

Going ahead to step 4:
421 can be fit into 3933 9 times, resulting in a remainder of 144.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtract 3789 from 3933 to get 144.
Include the next digit (7) from the dividend after 144, then repeat: 1447 / 421

Let's proceed to step 5:
421 can be fit into 1447 3 times, resulting in a remainder of 184.
Write down 3 as next digit of the result. 
Result so far: 93.0
If we subtract 1263 from 1447, we get 184.
Append the next digit (7) from the dividend to 184 and continue with: 1847 / 421

Step 6:
If we divide 1847 by 421, we get 4 and a remainder of 163.
The number 4 becomes the next digit in our result. 
Result so far: 934.0
Deduct 1684 from 1847 and we're left with 163.
Include the next digit (7) from the dividend after 163, then repeat: 1637 / 421

Going ahead to step 7:
When dividing 1637 by 421, we get 3 with a remainder of 374.
Use 3 as the next digit of our solution. 
Result so far: 9343.0
If we subtract 1263 from 1637, we get 374.
Include the next digit (8) from the dividend after 374, then repeat: 3748 / 421

On to step 8:
If we divide 3748 by 421, we get 8 and a remainder of 380.
Write down 8 as next digit of the result. 
Result so far: 93438.0
The remainder is 380 after subtracting 3368 from 3748.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

On to step 9:
The number 421 fits into 3800 9 times, leaving a remainder of 11.
The next digit of our result is 9. 
Result so far: 93438.9
Subtract 3789 from 3800 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 10:
421 goes into 110 0 times with a remainder of 110.
Use 0 as the next digit of our solution. 
Result so far: 93438.9
Deduct 0 from 110 and we're left with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Moving on to step 11:
The number 421 fits into 1100 2 times, leaving a remainder of 258.
The next digit of our result is 2. 
Result so far: 93438.902
If we subtract 842 from 1100, we get 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Going ahead to step 12:
421 can be fit into 2580 6 times, resulting in a remainder of 54.
Put 6 as the next digit of the answer. 
Result so far: 93438.9026
Subtracting 2526 from 2580 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 13:
When dividing 540 by 421, we get 1 with a remainder of 119.
Use 1 as the next digit of our solution. 
Result so far: 93438.90261
Subtract 421 from 540 to get 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Advancing to step 14:
421 can be fit into 1190 2 times, resulting in a remainder of 348.
Put 2 as the next digit of the answer. 
Result so far: 93438.902612
The remainder is 348 after subtracting 842 from 1190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Step 15:
If we divide 3480 by 421, we get 8 and a remainder of 112.
Record the quotient 8 as the next digit in the result. 
Result so far: 93438.9026128
If we take 3368 away from 3480, we end up with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Moving on to step 16:
421 goes into 1120 2 times with a remainder of 278.
Record the quotient 2 as the next digit in the result. 
Result so far: 93438.90261282
Subtracting 842 from 1120 leaves us 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.

After the division, we end up with 93438.90261282 and a remainder of 2.78e-07.
