Let's divide 7107351 by 402
We want to divide 7107351 by 402.

Going ahead to step 1:
7 divided by 402 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 402

Step 2:
If we divide 71 by 402, we get 0 and a remainder of 71.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 71 and we're left with 71.
Take the next digit (0) from the dividend and append it to 71, then repeat: 710 / 402

On to step 3:
402 can be fit into 710 1 times, resulting in a remainder of 308.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 402 from 710 and we're left with 308.
Grab the next digit (7) from the dividend, add it to 308, then carry on: 3087 / 402

Let's proceed to step 4:
402 goes into 3087 7 times with a remainder of 273.
Use 7 as the next digit of our solution. 
Result so far: 17.0
If we subtract 2814 from 3087, we get 273.
Append the next digit (3) from the dividend to 273 and continue with: 2733 / 402

Advancing to step 5:
2733 divided by 402 is 6 with a remainder of 321.
Use 6 as the next digit of our solution. 
Result so far: 176.0
Deduct 2412 from 2733 and we're left with 321.
Bring next digit (5) of the dividend behind the 321 and repeat the process: 3215 / 402

On to step 6:
402 can be fit into 3215 7 times, resulting in a remainder of 401.
The next digit of our result is 7. 
Result so far: 1767.0
Subtract 2814 from 3215 to get 401.
Bring next digit (1) of the dividend behind the 401 and repeat the process: 4011 / 402

Going ahead to step 7:
4011 divided by 402 is 9 with a remainder of 393.
Use 9 as the next digit of our solution. 
Result so far: 17679.0
If we subtract 3618 from 4011, we get 393.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3930, and continue the process.

Step 8:
3930 divided by 402 is 9 with a remainder of 312.
Record the quotient 9 as the next digit in the result. 
Result so far: 17679.9
Deduct 3618 from 3930 and we're left with 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

On to step 9:
When dividing 3120 by 402, we get 7 with a remainder of 306.
Record the quotient 7 as the next digit in the result. 
Result so far: 17679.97
If we subtract 2814 from 3120, we get 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Step 10:
The number 402 fits into 3060 7 times, leaving a remainder of 246.
Record the quotient 7 as the next digit in the result. 
Result so far: 17679.977
If we take 2814 away from 3060, we end up with 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

In conclusion, the division gives 17679.977 with a balance of 0.0246.
