79857100 ÷ 38 
Our goal is to divide 79857100 by 38.

Let's proceed to step 1:
38 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 38

Moving on to step 2:
The number 38 fits into 79 2 times, leaving a remainder of 3.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 76 from 79 and we're left with 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 38

Step 3:
When dividing 38 by 38, we get 1 with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 21.0
If we take 38 away from 38, we end up with 0.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 38

On to step 4:
The number 38 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 210.0
Deduct 0 from 5 and we're left with 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 38

On to step 5:
57 divided by 38 is 1 with a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 2101.0
If we take 38 away from 57, we end up with 19.
Fetch the next digit (1) from the dividend, attach it to 19 and continue: 191 / 38

Going ahead to step 6:
38 can be fit into 191 5 times, resulting in a remainder of 1.
Use 5 as the next digit of our solution. 
Result so far: 21015.0
Deduct 190 from 191 and we're left with 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 38

Going ahead to step 7:
38 can be fit into 10 0 times, resulting in a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 210150.0
Subtract 0 from 10 to get 10.
Take the next digit (0) from the dividend and append it to 10, then repeat: 100 / 38

Step 8:
The number 38 fits into 100 2 times, leaving a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 2101502.0
If we subtract 76 from 100, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 9:
When dividing 240 by 38, we get 6 with a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 2101502.6
Subtract 228 from 240 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 10:
If we divide 120 by 38, we get 3 and a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 2101502.63
Deduct 114 from 120 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 11:
38 can be fit into 60 1 times, resulting in a remainder of 22.
Write down 1 as next digit of the result. 
Result so far: 2101502.631
If we subtract 38 from 60, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 12:
220 divided by 38 is 5 with a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 2101502.6315
If we subtract 190 from 220, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 13:
38 goes into 300 7 times with a remainder of 34.
Write down 7 as next digit of the result. 
Result so far: 2101502.63157
If we subtract 266 from 300, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 14:
38 goes into 340 8 times with a remainder of 36.
Put 8 as the next digit of the answer. 
Result so far: 2101502.631578
If we take 304 away from 340, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 15:
When dividing 360 by 38, we get 9 with a remainder of 18.
Put 9 as the next digit of the answer. 
Result so far: 2101502.6315789
The remainder is 18 after subtracting 342 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 16:
38 goes into 180 4 times with a remainder of 28.
Use 4 as the next digit of our solution. 
Result so far: 2101502.63157894
Subtract 152 from 180 to get 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 2101502.63157894, with a leftover of 2.8e-08.
