70039457 ÷ 437 
We want to divide 70039457 by 437.

On to step 1:
437 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 437

Moving on to step 2:
70 divided by 437 is 0 with a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 70, we get 70.
Fetch the next digit (0) from the dividend, attach it to 70 and continue: 700 / 437

Let's proceed to step 3:
437 can be fit into 700 1 times, resulting in a remainder of 263.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 437 from 700 and we're left with 263.
Bring next digit (3) of the dividend behind the 263 and repeat the process: 2633 / 437

Advancing to step 4:
The number 437 fits into 2633 6 times, leaving a remainder of 11.
The next digit of our result is 6. 
Result so far: 16.0
Deduct 2622 from 2633 and we're left with 11.
Include the next digit (9) from the dividend after 11, then repeat: 119 / 437

On to step 5:
The number 437 fits into 119 0 times, leaving a remainder of 119.
Write down 0 as next digit of the result. 
Result so far: 160.0
Subtract 0 from 119 to get 119.
Take the next digit (4) from the dividend and append it to 119, then repeat: 1194 / 437

Moving on to step 6:
The number 437 fits into 1194 2 times, leaving a remainder of 320.
Record the quotient 2 as the next digit in the result. 
Result so far: 1602.0
If we take 874 away from 1194, we end up with 320.
Grab the next digit (5) from the dividend, add it to 320, then carry on: 3205 / 437

On to step 7:
When dividing 3205 by 437, we get 7 with a remainder of 146.
The next digit of our result is 7. 
Result so far: 16027.0
Subtract 3059 from 3205 to get 146.
Take the next digit (7) from the dividend and append it to 146, then repeat: 1467 / 437

On to step 8:
When dividing 1467 by 437, we get 3 with a remainder of 156.
Use 3 as the next digit of our solution. 
Result so far: 160273.0
If we take 1311 away from 1467, we end up with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Step 9:
437 can be fit into 1560 3 times, resulting in a remainder of 249.
Record the quotient 3 as the next digit in the result. 
Result so far: 160273.3
The remainder is 249 after subtracting 1311 from 1560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2490, and continue the process.

Step 10:
437 goes into 2490 5 times with a remainder of 305.
Use 5 as the next digit of our solution. 
Result so far: 160273.35
Subtracting 2185 from 2490 leaves us with 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

On to step 11:
The number 437 fits into 3050 6 times, leaving a remainder of 428.
Record the quotient 6 as the next digit in the result. 
Result so far: 160273.356
Subtract 2622 from 3050 to get 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

Moving on to step 12:
If we divide 4280 by 437, we get 9 and a remainder of 347.
Write down 9 as next digit of the result. 
Result so far: 160273.3569
Subtracting 3933 from 4280 leaves us with 347.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3470, and continue the process.

Going ahead to step 13:
437 goes into 3470 7 times with a remainder of 411.
Use 7 as the next digit of our solution. 
Result so far: 160273.35697
Subtract 3059 from 3470 to get 411.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4110, and continue the process.

Advancing to step 14:
The number 437 fits into 4110 9 times, leaving a remainder of 177.
The next digit of our result is 9. 
Result so far: 160273.356979
Deduct 3933 from 4110 and we're left with 177.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

Advancing to step 15:
If we divide 1770 by 437, we get 4 and a remainder of 22.
Record the quotient 4 as the next digit in the result. 
Result so far: 160273.3569794
Deduct 1748 from 1770 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 16:
437 can be fit into 220 0 times, resulting in a remainder of 220.
The number 0 becomes the next digit in our result. 
Result so far: 160273.3569794
Subtract 0 from 220 to get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

In conclusion, the division gives 160273.3569794 with a balance of 2.2e-07.
