70457690 ÷ 207 
We want to divide 70457690 by 207.

Step 1:
If we divide 7 by 207, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 207

Step 2:
When dividing 70 by 207, we get 0 with a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 70 after subtracting 0 from 70.
Take the next digit (4) from the dividend and append it to 70, then repeat: 704 / 207

Going ahead to step 3:
207 can be fit into 704 3 times, resulting in a remainder of 83.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 621 from 704 to get 83.
Append the next digit (5) from the dividend to 83 and continue with: 835 / 207

Advancing to step 4:
When dividing 835 by 207, we get 4 with a remainder of 7.
Record the quotient 4 as the next digit in the result. 
Result so far: 34.0
If we take 828 away from 835, we end up with 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 207

Moving on to step 5:
If we divide 77 by 207, we get 0 and a remainder of 77.
Record the quotient 0 as the next digit in the result. 
Result so far: 340.0
If we subtract 0 from 77, we get 77.
Bring next digit (6) of the dividend behind the 77 and repeat the process: 776 / 207

Advancing to step 6:
When dividing 776 by 207, we get 3 with a remainder of 155.
The number 3 becomes the next digit in our result. 
Result so far: 3403.0
Subtracting 621 from 776 leaves us with 155.
Take the next digit (9) from the dividend and append it to 155, then repeat: 1559 / 207

Let's proceed to step 7:
207 goes into 1559 7 times with a remainder of 110.
The number 7 becomes the next digit in our result. 
Result so far: 34037.0
If we subtract 1449 from 1559, we get 110.
Append the next digit (0) from the dividend to 110 and continue with: 1100 / 207

Moving on to step 8:
When dividing 1100 by 207, we get 5 with a remainder of 65.
The next digit of our result is 5. 
Result so far: 340375.0
The remainder is 65 after subtracting 1035 from 1100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Going ahead to step 9:
207 goes into 650 3 times with a remainder of 29.
The number 3 becomes the next digit in our result. 
Result so far: 340375.3
If we subtract 621 from 650, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 10:
When dividing 290 by 207, we get 1 with a remainder of 83.
The number 1 becomes the next digit in our result. 
Result so far: 340375.31
If we subtract 207 from 290, we get 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Going ahead to step 11:
The number 207 fits into 830 4 times, leaving a remainder of 2.
The next digit of our result is 4. 
Result so far: 340375.314
If we take 828 away from 830, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 12:
207 can be fit into 20 0 times, resulting in a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 340375.314
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 13:
207 goes into 200 0 times with a remainder of 200.
Use 0 as the next digit of our solution. 
Result so far: 340375.314
If we take 0 away from 200, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

The final result is 340375.314 with a remainder of 0.0002.
