We're dividing 34379531 by 801 
We want to divide 34379531 by 801.

Step 1:
801 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 801

Advancing to step 2:
If we divide 34 by 801, we get 0 and a remainder of 34.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 34 after subtracting 0 from 34.
Bring next digit (3) of the dividend behind the 34 and repeat the process: 343 / 801

Moving on to step 3:
If we divide 343 by 801, we get 0 and a remainder of 343.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 343 and we're left with 343.
Include the next digit (7) from the dividend after 343, then repeat: 3437 / 801

Moving on to step 4:
801 goes into 3437 4 times with a remainder of 233.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 233 after subtracting 3204 from 3437.
Fetch the next digit (9) from the dividend, attach it to 233 and continue: 2339 / 801

Going ahead to step 5:
801 goes into 2339 2 times with a remainder of 737.
Write down 2 as next digit of the result. 
Result so far: 42.0
Deduct 1602 from 2339 and we're left with 737.
Grab the next digit (5) from the dividend, add it to 737, then carry on: 7375 / 801

On to step 6:
When dividing 7375 by 801, we get 9 with a remainder of 166.
Use 9 as the next digit of our solution. 
Result so far: 429.0
Deduct 7209 from 7375 and we're left with 166.
Take the next digit (3) from the dividend and append it to 166, then repeat: 1663 / 801

Step 7:
If we divide 1663 by 801, we get 2 and a remainder of 61.
Write down 2 as next digit of the result. 
Result so far: 4292.0
Deduct 1602 from 1663 and we're left with 61.
Fetch the next digit (1) from the dividend, attach it to 61 and continue: 611 / 801

Let's proceed to step 8:
The number 801 fits into 611 0 times, leaving a remainder of 611.
The number 0 becomes the next digit in our result. 
Result so far: 42920.0
If we take 0 away from 611, we end up with 611.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6110, and continue the process.

Advancing to step 9:
When dividing 6110 by 801, we get 7 with a remainder of 503.
The next digit of our result is 7. 
Result so far: 42920.7
Subtracting 5607 from 6110 leaves us with 503.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5030, and continue the process.

Moving on to step 10:
5030 divided by 801 is 6 with a remainder of 224.
The number 6 becomes the next digit in our result. 
Result so far: 42920.76
Deduct 4806 from 5030 and we're left with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Advancing to step 11:
801 can be fit into 2240 2 times, resulting in a remainder of 638.
The next digit of our result is 2. 
Result so far: 42920.762
The remainder is 638 after subtracting 1602 from 2240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6380, and continue the process.

Step 12:
When dividing 6380 by 801, we get 7 with a remainder of 773.
Put 7 as the next digit of the answer. 
Result so far: 42920.7627
Subtracting 5607 from 6380 leaves us with 773.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7730, and continue the process.

Going ahead to step 13:
If we divide 7730 by 801, we get 9 and a remainder of 521.
Use 9 as the next digit of our solution. 
Result so far: 42920.76279
Deduct 7209 from 7730 and we're left with 521.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5210, and continue the process.

Advancing to step 14:
801 goes into 5210 6 times with a remainder of 404.
Record the quotient 6 as the next digit in the result. 
Result so far: 42920.762796
Subtract 4806 from 5210 to get 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Going ahead to step 15:
The number 801 fits into 4040 5 times, leaving a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 42920.7627965
Deduct 4005 from 4040 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 16:
801 can be fit into 350 0 times, resulting in a remainder of 350.
Put 0 as the next digit of the answer. 
Result so far: 42920.7627965
Subtract 0 from 350 to get 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

The quotient of the division is 42920.7627965, and the remainder is 3.5e-07.
