21091077 ÷ 347 
We're looking to find how many times 347 goes into 21091077.

Advancing to step 1:
347 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 347

Advancing to step 2:
If we divide 21 by 347, we get 0 and a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Include the next digit (0) from the dividend after 21, then repeat: 210 / 347

On to step 3:
347 can be fit into 210 0 times, resulting in a remainder of 210.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 210 leaves us with 210.
Grab the next digit (9) from the dividend, add it to 210, then carry on: 2109 / 347

On to step 4:
347 can be fit into 2109 6 times, resulting in a remainder of 27.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Deduct 2082 from 2109 and we're left with 27.
Bring next digit (1) of the dividend behind the 27 and repeat the process: 271 / 347

Going ahead to step 5:
If we divide 271 by 347, we get 0 and a remainder of 271.
Put 0 as the next digit of the answer. 
Result so far: 60.0
Subtract 0 from 271 to get 271.
Include the next digit (0) from the dividend after 271, then repeat: 2710 / 347

Advancing to step 6:
If we divide 2710 by 347, we get 7 and a remainder of 281.
Record the quotient 7 as the next digit in the result. 
Result so far: 607.0
The remainder is 281 after subtracting 2429 from 2710.
Append the next digit (7) from the dividend to 281 and continue with: 2817 / 347

Advancing to step 7:
347 can be fit into 2817 8 times, resulting in a remainder of 41.
Use 8 as the next digit of our solution. 
Result so far: 6078.0
Subtracting 2776 from 2817 leaves us with 41.
Append the next digit (7) from the dividend to 41 and continue with: 417 / 347

On to step 8:
If we divide 417 by 347, we get 1 and a remainder of 70.
Write down 1 as next digit of the result. 
Result so far: 60781.0
Subtract 347 from 417 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 9:
700 divided by 347 is 2 with a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 60781.2
If we take 694 away from 700, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 10:
347 goes into 60 0 times with a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 60781.2
Subtracting 0 from 60 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 11:
If we divide 600 by 347, we get 1 and a remainder of 253.
Use 1 as the next digit of our solution. 
Result so far: 60781.201
The remainder is 253 after subtracting 347 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

Step 12:
2530 divided by 347 is 7 with a remainder of 101.
The number 7 becomes the next digit in our result. 
Result so far: 60781.2017
The remainder is 101 after subtracting 2429 from 2530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Advancing to step 13:
1010 divided by 347 is 2 with a remainder of 316.
Put 2 as the next digit of the answer. 
Result so far: 60781.20172
If we subtract 694 from 1010, we get 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

Step 14:
When dividing 3160 by 347, we get 9 with a remainder of 37.
The next digit of our result is 9. 
Result so far: 60781.201729
Subtract 3123 from 3160 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 15:
347 goes into 370 1 times with a remainder of 23.
Record the quotient 1 as the next digit in the result. 
Result so far: 60781.2017291
The remainder is 23 after subtracting 347 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 16:
230 divided by 347 is 0 with a remainder of 230.
Put 0 as the next digit of the answer. 
Result so far: 60781.2017291
If we subtract 0 from 230, we get 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

The final result is 60781.2017291 with a remainder of 2.3e-07.
