Let's divide 70209409 by 253
We want to divide 70209409 by 253.

Step 1:
253 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 253

Let's proceed to step 2:
253 can be fit into 70 0 times, resulting in a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 70, we end up with 70.
Grab the next digit (2) from the dividend, add it to 70, then carry on: 702 / 253

Advancing to step 3:
253 goes into 702 2 times with a remainder of 196.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 196 after subtracting 506 from 702.
Bring next digit (0) of the dividend behind the 196 and repeat the process: 1960 / 253

Advancing to step 4:
1960 divided by 253 is 7 with a remainder of 189.
The number 7 becomes the next digit in our result. 
Result so far: 27.0
Deduct 1771 from 1960 and we're left with 189.
Fetch the next digit (9) from the dividend, attach it to 189 and continue: 1899 / 253

Advancing to step 5:
When dividing 1899 by 253, we get 7 with a remainder of 128.
Use 7 as the next digit of our solution. 
Result so far: 277.0
If we subtract 1771 from 1899, we get 128.
Append the next digit (4) from the dividend to 128 and continue with: 1284 / 253

Let's proceed to step 6:
1284 divided by 253 is 5 with a remainder of 19.
Put 5 as the next digit of the answer. 
Result so far: 2775.0
The remainder is 19 after subtracting 1265 from 1284.
Bring next digit (0) of the dividend behind the 19 and repeat the process: 190 / 253

Step 7:
190 divided by 253 is 0 with a remainder of 190.
The number 0 becomes the next digit in our result. 
Result so far: 27750.0
Deduct 0 from 190 and we're left with 190.
Include the next digit (9) from the dividend after 190, then repeat: 1909 / 253

Let's proceed to step 8:
253 can be fit into 1909 7 times, resulting in a remainder of 138.
Use 7 as the next digit of our solution. 
Result so far: 277507.0
Deduct 1771 from 1909 and we're left with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Advancing to step 9:
When dividing 1380 by 253, we get 5 with a remainder of 115.
Record the quotient 5 as the next digit in the result. 
Result so far: 277507.5
If we take 1265 away from 1380, we end up with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

On to step 10:
1150 divided by 253 is 4 with a remainder of 138.
The number 4 becomes the next digit in our result. 
Result so far: 277507.54
If we take 1012 away from 1150, we end up with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Going ahead to step 11:
1380 divided by 253 is 5 with a remainder of 115.
The next digit of our result is 5. 
Result so far: 277507.545
Subtracting 1265 from 1380 leaves us with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Let's proceed to step 12:
If we divide 1150 by 253, we get 4 and a remainder of 138.
Put 4 as the next digit of the answer. 
Result so far: 277507.5454
The remainder is 138 after subtracting 1012 from 1150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Going ahead to step 13:
253 goes into 1380 5 times with a remainder of 115.
Use 5 as the next digit of our solution. 
Result so far: 277507.54545
The remainder is 115 after subtracting 1265 from 1380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Let's proceed to step 14:
1150 divided by 253 is 4 with a remainder of 138.
Put 4 as the next digit of the answer. 
Result so far: 277507.545454
The remainder is 138 after subtracting 1012 from 1150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Going ahead to step 15:
253 can be fit into 1380 5 times, resulting in a remainder of 115.
Use 5 as the next digit of our solution. 
Result so far: 277507.5454545
Subtracting 1265 from 1380 leaves us with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Step 16:
253 goes into 1150 4 times with a remainder of 138.
Write down 4 as next digit of the result. 
Result so far: 277507.54545454
Deduct 1012 from 1150 and we're left with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

The final outcome is 277507.54545454, with a leftover of 1.38e-07.
