2100830 ÷ 152 
Let's see how many times 152 fits into 2100830.

Moving on to step 1:
The number 152 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 152

Going ahead to step 2:
152 can be fit into 21 0 times, resulting in a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Bring next digit (0) of the dividend behind the 21 and repeat the process: 210 / 152

Moving on to step 3:
152 goes into 210 1 times with a remainder of 58.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 152 away from 210, we end up with 58.
Append the next digit (0) from the dividend to 58 and continue with: 580 / 152

Going ahead to step 4:
152 goes into 580 3 times with a remainder of 124.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Deduct 456 from 580 and we're left with 124.
Grab the next digit (8) from the dividend, add it to 124, then carry on: 1248 / 152

On to step 5:
When dividing 1248 by 152, we get 8 with a remainder of 32.
Record the quotient 8 as the next digit in the result. 
Result so far: 138.0
Deduct 1216 from 1248 and we're left with 32.
Bring next digit (3) of the dividend behind the 32 and repeat the process: 323 / 152

Going ahead to step 6:
152 can be fit into 323 2 times, resulting in a remainder of 19.
Put 2 as the next digit of the answer. 
Result so far: 1382.0
If we subtract 304 from 323, we get 19.
Bring next digit (0) of the dividend behind the 19 and repeat the process: 190 / 152

Advancing to step 7:
When dividing 190 by 152, we get 1 with a remainder of 38.
Put 1 as the next digit of the answer. 
Result so far: 13821.0
If we subtract 152 from 190, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 8:
380 divided by 152 is 2 with a remainder of 76.
The number 2 becomes the next digit in our result. 
Result so far: 13821.2
Deduct 304 from 380 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 9:
The number 152 fits into 760 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 13821.25
Subtract 760 from 760 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 10:
152 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 13821.25
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 11:
0 divided by 152 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 13821.25
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 13821.25 and a remainder of 0.0.
