Let's divide 70917738 by 451
Our goal is to divide 70917738 by 451.

Let's proceed to step 1:
7 divided by 451 is 0 with a remainder of 7.
Write down 0 as next digit of the 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 / 451

Step 2:
When dividing 70 by 451, we get 0 with a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 70, we end up with 70.
Include the next digit (9) from the dividend after 70, then repeat: 709 / 451

Advancing to step 3:
451 can be fit into 709 1 times, resulting in a remainder of 258.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 451 from 709 and we're left with 258.
Take the next digit (1) from the dividend and append it to 258, then repeat: 2581 / 451

Let's proceed to step 4:
When dividing 2581 by 451, we get 5 with a remainder of 326.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Subtracting 2255 from 2581 leaves us with 326.
Append the next digit (7) from the dividend to 326 and continue with: 3267 / 451

Moving on to step 5:
3267 divided by 451 is 7 with a remainder of 110.
Use 7 as the next digit of our solution. 
Result so far: 157.0
If we subtract 3157 from 3267, we get 110.
Bring next digit (7) of the dividend behind the 110 and repeat the process: 1107 / 451

Moving on to step 6:
When dividing 1107 by 451, we get 2 with a remainder of 205.
The next digit of our result is 2. 
Result so far: 1572.0
The remainder is 205 after subtracting 902 from 1107.
Fetch the next digit (3) from the dividend, attach it to 205 and continue: 2053 / 451

Advancing to step 7:
If we divide 2053 by 451, we get 4 and a remainder of 249.
Record the quotient 4 as the next digit in the result. 
Result so far: 15724.0
If we take 1804 away from 2053, we end up with 249.
Grab the next digit (8) from the dividend, add it to 249, then carry on: 2498 / 451

Going ahead to step 8:
The number 451 fits into 2498 5 times, leaving a remainder of 243.
The number 5 becomes the next digit in our result. 
Result so far: 157245.0
If we subtract 2255 from 2498, we get 243.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2430, and continue the process.

Advancing to step 9:
451 can be fit into 2430 5 times, resulting in a remainder of 175.
Write down 5 as next digit of the result. 
Result so far: 157245.5
Deduct 2255 from 2430 and we're left with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

On to step 10:
451 can be fit into 1750 3 times, resulting in a remainder of 397.
Write down 3 as next digit of the result. 
Result so far: 157245.53
The remainder is 397 after subtracting 1353 from 1750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3970, and continue the process.

Advancing to step 11:
3970 divided by 451 is 8 with a remainder of 362.
Use 8 as the next digit of our solution. 
Result so far: 157245.538
If we subtract 3608 from 3970, we get 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

Step 12:
451 can be fit into 3620 8 times, resulting in a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 157245.5388
The remainder is 12 after subtracting 3608 from 3620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final outcome is 157245.5388, with a leftover of 0.00012.
