39219335 ÷ 421 
Let's see how many times 421 fits into 39219335.

Let's proceed to step 1:
If we divide 3 by 421, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 421

Moving on to step 2:
421 can be fit into 39 0 times, resulting in a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Bring next digit (2) of the dividend behind the 39 and repeat the process: 392 / 421

Moving on to step 3:
421 goes into 392 0 times with a remainder of 392.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 392 and we're left with 392.
Take the next digit (1) from the dividend and append it to 392, then repeat: 3921 / 421

On to step 4:
3921 divided by 421 is 9 with a remainder of 132.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
The remainder is 132 after subtracting 3789 from 3921.
Take the next digit (9) from the dividend and append it to 132, then repeat: 1329 / 421

Going ahead to step 5:
1329 divided by 421 is 3 with a remainder of 66.
Record the quotient 3 as the next digit in the result. 
Result so far: 93.0
Subtract 1263 from 1329 to get 66.
Include the next digit (3) from the dividend after 66, then repeat: 663 / 421

Moving on to step 6:
When dividing 663 by 421, we get 1 with a remainder of 242.
The next digit of our result is 1. 
Result so far: 931.0
If we take 421 away from 663, we end up with 242.
Fetch the next digit (3) from the dividend, attach it to 242 and continue: 2423 / 421

Step 7:
When dividing 2423 by 421, we get 5 with a remainder of 318.
Use 5 as the next digit of our solution. 
Result so far: 9315.0
Deduct 2105 from 2423 and we're left with 318.
Take the next digit (5) from the dividend and append it to 318, then repeat: 3185 / 421

On to step 8:
When dividing 3185 by 421, we get 7 with a remainder of 238.
Write down 7 as next digit of the result. 
Result so far: 93157.0
Subtract 2947 from 3185 to get 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Going ahead to step 9:
The number 421 fits into 2380 5 times, leaving a remainder of 275.
Use 5 as the next digit of our solution. 
Result so far: 93157.5
The remainder is 275 after subtracting 2105 from 2380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Let's proceed to step 10:
When dividing 2750 by 421, we get 6 with a remainder of 224.
Put 6 as the next digit of the answer. 
Result so far: 93157.56
Subtracting 2526 from 2750 leaves us with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Advancing to step 11:
The number 421 fits into 2240 5 times, leaving a remainder of 135.
Write down 5 as next digit of the result. 
Result so far: 93157.565
If we subtract 2105 from 2240, we get 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Advancing to step 12:
When dividing 1350 by 421, we get 3 with a remainder of 87.
Put 3 as the next digit of the answer. 
Result so far: 93157.5653
If we take 1263 away from 1350, we end up with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

On to step 13:
421 goes into 870 2 times with a remainder of 28.
Write down 2 as next digit of the result. 
Result so far: 93157.56532
Subtracting 842 from 870 leaves us 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.

Moving on to step 14:
421 goes into 280 0 times with a remainder of 280.
Put 0 as the next digit of the answer. 
Result so far: 93157.56532
Subtracting 0 from 280 leaves us with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Advancing to step 15:
When dividing 2800 by 421, we get 6 with a remainder of 274.
The next digit of our result is 6. 
Result so far: 93157.5653206
Deduct 2526 from 2800 and we're left with 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Let's proceed to step 16:
The number 421 fits into 2740 6 times, leaving a remainder of 214.
The number 6 becomes the next digit in our result. 
Result so far: 93157.56532066
If we subtract 2526 from 2740, we get 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

After the division, we end up with 93157.56532066 and a remainder of 2.14e-07.
