83409917 ÷ 351 
We want to divide 83409917 by 351.

Let's proceed to step 1:
The number 351 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 351

Moving on to step 2:
351 can be fit into 83 0 times, resulting in a remainder of 83.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 83, we end up with 83.
Fetch the next digit (4) from the dividend, attach it to 83 and continue: 834 / 351

Step 3:
834 divided by 351 is 2 with a remainder of 132.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 702 from 834 to get 132.
Include the next digit (0) from the dividend after 132, then repeat: 1320 / 351

Step 4:
351 goes into 1320 3 times with a remainder of 267.
Put 3 as the next digit of the answer. 
Result so far: 23.0
If we subtract 1053 from 1320, we get 267.
Bring next digit (9) of the dividend behind the 267 and repeat the process: 2679 / 351

On to step 5:
When dividing 2679 by 351, we get 7 with a remainder of 222.
Use 7 as the next digit of our solution. 
Result so far: 237.0
Deduct 2457 from 2679 and we're left with 222.
Append the next digit (9) from the dividend to 222 and continue with: 2229 / 351

Advancing to step 6:
The number 351 fits into 2229 6 times, leaving a remainder of 123.
Use 6 as the next digit of our solution. 
Result so far: 2376.0
Deduct 2106 from 2229 and we're left with 123.
Include the next digit (1) from the dividend after 123, then repeat: 1231 / 351

Moving on to step 7:
1231 divided by 351 is 3 with a remainder of 178.
Put 3 as the next digit of the answer. 
Result so far: 23763.0
Subtract 1053 from 1231 to get 178.
Include the next digit (7) from the dividend after 178, then repeat: 1787 / 351

Moving on to step 8:
351 can be fit into 1787 5 times, resulting in a remainder of 32.
The next digit of our result is 5. 
Result so far: 237635.0
Deduct 1755 from 1787 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 9:
The number 351 fits into 320 0 times, leaving a remainder of 320.
Write down 0 as next digit of the result. 
Result so far: 237635.0
Deduct 0 from 320 and we're left with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Advancing to step 10:
351 can be fit into 3200 9 times, resulting in a remainder of 41.
Record the quotient 9 as the next digit in the result. 
Result so far: 237635.09
Subtract 3159 from 3200 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 11:
If we divide 410 by 351, we get 1 and a remainder of 59.
Write down 1 as next digit of the result. 
Result so far: 237635.091
Subtracting 351 from 410 leaves us with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Let's proceed to step 12:
If we divide 590 by 351, we get 1 and a remainder of 239.
Put 1 as the next digit of the answer. 
Result so far: 237635.0911
Subtract 351 from 590 to get 239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

The final outcome is 237635.0911, with a leftover of 0.00239.
