Let's divide 39837581 by 428
We want to figure out the number of times 39837581 can be divided by 428.

On to step 1:
When dividing 3 by 428, we get 0 with 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.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 428

Going ahead to step 2:
428 can be fit into 39 0 times, resulting in a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Append the next digit (8) from the dividend to 39 and continue with: 398 / 428

Let's proceed to step 3:
The number 428 fits into 398 0 times, leaving a remainder of 398.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 398 to get 398.
Bring next digit (3) of the dividend behind the 398 and repeat the process: 3983 / 428

Going ahead to step 4:
If we divide 3983 by 428, we get 9 and a remainder of 131.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we take 3852 away from 3983, we end up with 131.
Bring next digit (7) of the dividend behind the 131 and repeat the process: 1317 / 428

Going ahead to step 5:
428 goes into 1317 3 times with a remainder of 33.
Use 3 as the next digit of our solution. 
Result so far: 93.0
Subtract 1284 from 1317 to get 33.
Fetch the next digit (5) from the dividend, attach it to 33 and continue: 335 / 428

Going ahead to step 6:
428 can be fit into 335 0 times, resulting in a remainder of 335.
Put 0 as the next digit of the answer. 
Result so far: 930.0
If we subtract 0 from 335, we get 335.
Grab the next digit (8) from the dividend, add it to 335, then carry on: 3358 / 428

Let's proceed to step 7:
If we divide 3358 by 428, we get 7 and a remainder of 362.
Put 7 as the next digit of the answer. 
Result so far: 9307.0
Subtract 2996 from 3358 to get 362.
Include the next digit (1) from the dividend after 362, then repeat: 3621 / 428

Let's proceed to step 8:
428 can be fit into 3621 8 times, resulting in a remainder of 197.
The next digit of our result is 8. 
Result so far: 93078.0
Subtracting 3424 from 3621 leaves us with 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

Going ahead to step 9:
428 can be fit into 1970 4 times, resulting in a remainder of 258.
The next digit of our result is 4. 
Result so far: 93078.4
The remainder is 258 after subtracting 1712 from 1970.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

On to step 10:
428 goes into 2580 6 times with a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 93078.46
If we take 2568 away from 2580, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 11:
120 divided by 428 is 0 with a remainder of 120.
Use 0 as the next digit of our solution. 
Result so far: 93078.46
Deduct 0 from 120 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Step 12:
The number 428 fits into 1200 2 times, leaving a remainder of 344.
The next digit of our result is 2. 
Result so far: 93078.4602
Subtract 856 from 1200 to get 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Let's proceed to step 13:
When dividing 3440 by 428, we get 8 with a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 93078.46028
If we subtract 3424 from 3440, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 14:
428 can be fit into 160 0 times, resulting in a remainder of 160.
Use 0 as the next digit of our solution. 
Result so far: 93078.46028
If we subtract 0 from 160, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Step 15:
If we divide 1600 by 428, we get 3 and a remainder of 316.
The number 3 becomes the next digit in our result. 
Result so far: 93078.4602803
Deduct 1284 from 1600 and we're left with 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

Moving on to step 16:
428 can be fit into 3160 7 times, resulting in a remainder of 164.
Record the quotient 7 as the next digit in the result. 
Result so far: 93078.46028037
Subtracting 2996 from 3160 leaves us with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

In conclusion, the division gives 93078.46028037 with a balance of 1.64e-07.
