Let's divide 42991987 by 435
We want to divide 42991987 by 435.

Let's proceed to step 1:
When dividing 4 by 435, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 435

Step 2:
435 can be fit into 42 0 times, resulting in a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Include the next digit (9) from the dividend after 42, then repeat: 429 / 435

Step 3:
The number 435 fits into 429 0 times, leaving a remainder of 429.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 429 and we're left with 429.
Bring next digit (9) of the dividend behind the 429 and repeat the process: 4299 / 435

Advancing to step 4:
The number 435 fits into 4299 9 times, leaving a remainder of 384.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtracting 3915 from 4299 leaves us with 384.
Include the next digit (1) from the dividend after 384, then repeat: 3841 / 435

Moving on to step 5:
If we divide 3841 by 435, we get 8 and a remainder of 361.
Use 8 as the next digit of our solution. 
Result so far: 98.0
The remainder is 361 after subtracting 3480 from 3841.
Fetch the next digit (9) from the dividend, attach it to 361 and continue: 3619 / 435

On to step 6:
3619 divided by 435 is 8 with a remainder of 139.
Use 8 as the next digit of our solution. 
Result so far: 988.0
Subtracting 3480 from 3619 leaves us with 139.
Grab the next digit (8) from the dividend, add it to 139, then carry on: 1398 / 435

Advancing to step 7:
435 goes into 1398 3 times with a remainder of 93.
Write down 3 as next digit of the result. 
Result so far: 9883.0
If we take 1305 away from 1398, we end up with 93.
Bring next digit (7) of the dividend behind the 93 and repeat the process: 937 / 435

Moving on to step 8:
937 divided by 435 is 2 with a remainder of 67.
Record the quotient 2 as the next digit in the result. 
Result so far: 98832.0
Subtracting 870 from 937 leaves us with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

On to step 9:
670 divided by 435 is 1 with a remainder of 235.
The number 1 becomes the next digit in our result. 
Result so far: 98832.1
The remainder is 235 after subtracting 435 from 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Let's proceed to step 10:
If we divide 2350 by 435, we get 5 and a remainder of 175.
Write down 5 as next digit of the result. 
Result so far: 98832.15
Deduct 2175 from 2350 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.

Going ahead to step 11:
When dividing 1750 by 435, we get 4 with a remainder of 10.
Put 4 as the next digit of the answer. 
Result so far: 98832.154
If we subtract 1740 from 1750, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 12:
100 divided by 435 is 0 with a remainder of 100.
Put 0 as the next digit of the answer. 
Result so far: 98832.154
If we take 0 away from 100, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 13:
When dividing 1000 by 435, we get 2 with a remainder of 130.
Put 2 as the next digit of the answer. 
Result so far: 98832.15402
The remainder is 130 after subtracting 870 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Let's proceed to step 14:
The number 435 fits into 1300 2 times, leaving a remainder of 430.
Use 2 as the next digit of our solution. 
Result so far: 98832.154022
Subtracting 870 from 1300 leaves us with 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

The final result is 98832.154022 with a remainder of 4.3e-05.
