10202130 divided by 402 
We want to divide 10202130 by 402.

Let's proceed to step 1:
1 divided by 402 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 402

Advancing to step 2:
If we divide 10 by 402, we get 0 and a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 10, we end up with 10.
Include the next digit (2) from the dividend after 10, then repeat: 102 / 402

Step 3:
402 goes into 102 0 times with a remainder of 102.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 102 and we're left with 102.
Include the next digit (0) from the dividend after 102, then repeat: 1020 / 402

On to step 4:
If we divide 1020 by 402, we get 2 and a remainder of 216.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 804 from 1020 leaves us with 216.
Append the next digit (2) from the dividend to 216 and continue with: 2162 / 402

Let's proceed to step 5:
When dividing 2162 by 402, we get 5 with a remainder of 152.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
If we take 2010 away from 2162, we end up with 152.
Append the next digit (1) from the dividend to 152 and continue with: 1521 / 402

Let's proceed to step 6:
The number 402 fits into 1521 3 times, leaving a remainder of 315.
Use 3 as the next digit of our solution. 
Result so far: 253.0
Subtract 1206 from 1521 to get 315.
Bring next digit (3) of the dividend behind the 315 and repeat the process: 3153 / 402

Let's proceed to step 7:
402 goes into 3153 7 times with a remainder of 339.
The number 7 becomes the next digit in our result. 
Result so far: 2537.0
If we subtract 2814 from 3153, we get 339.
Bring next digit (0) of the dividend behind the 339 and repeat the process: 3390 / 402

Moving on to step 8:
When dividing 3390 by 402, we get 8 with a remainder of 174.
Record the quotient 8 as the next digit in the result. 
Result so far: 25378.0
If we take 3216 away from 3390, we end up with 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Advancing to step 9:
If we divide 1740 by 402, we get 4 and a remainder of 132.
Put 4 as the next digit of the answer. 
Result so far: 25378.4
Subtracting 1608 from 1740 leaves us with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Advancing to step 10:
402 goes into 1320 3 times with a remainder of 114.
Use 3 as the next digit of our solution. 
Result so far: 25378.43
If we take 1206 away from 1320, we end up with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Let's proceed to step 11:
If we divide 1140 by 402, we get 2 and a remainder of 336.
Write down 2 as next digit of the result. 
Result so far: 25378.432
Subtracting 804 from 1140 leaves us with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Advancing to step 12:
402 goes into 3360 8 times with a remainder of 144.
Write down 8 as next digit of the result. 
Result so far: 25378.4328
The remainder is 144 after subtracting 3216 from 3360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Going ahead to step 13:
1440 divided by 402 is 3 with a remainder of 234.
Write down 3 as next digit of the result. 
Result so far: 25378.43283
If we take 1206 away from 1440, we end up with 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Let's proceed to step 14:
The number 402 fits into 2340 5 times, leaving a remainder of 330.
Put 5 as the next digit of the answer. 
Result so far: 25378.432835
Deduct 2010 from 2340 and we're left with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Moving on to step 15:
402 can be fit into 3300 8 times, resulting in a remainder of 84.
Use 8 as the next digit of our solution. 
Result so far: 25378.4328358
The remainder is 84 after subtracting 3216 from 3300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Step 16:
The number 402 fits into 840 2 times, leaving a remainder of 36.
Use 2 as the next digit of our solution. 
Result so far: 25378.43283582
If we take 804 away from 840, 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.

In conclusion, the division gives 25378.43283582 with a balance of 3.6e-08.
