21100735 ÷ 353 
We're looking to find how many times 353 goes into 21100735.

Moving on to step 1:
2 divided by 353 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 353

Moving on to step 2:
21 divided by 353 is 0 with a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Grab the next digit (1) from the dividend, add it to 21, then carry on: 211 / 353

Advancing to step 3:
The number 353 fits into 211 0 times, leaving a remainder of 211.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 211 leaves us with 211.
Fetch the next digit (0) from the dividend, attach it to 211 and continue: 2110 / 353

Moving on to step 4:
When dividing 2110 by 353, we get 5 with a remainder of 345.
Write down 5 as next digit of the result. 
Result so far: 5.0
The remainder is 345 after subtracting 1765 from 2110.
Append the next digit (0) from the dividend to 345 and continue with: 3450 / 353

Moving on to step 5:
When dividing 3450 by 353, we get 9 with a remainder of 273.
Use 9 as the next digit of our solution. 
Result so far: 59.0
The remainder is 273 after subtracting 3177 from 3450.
Append the next digit (7) from the dividend to 273 and continue with: 2737 / 353

Step 6:
353 goes into 2737 7 times with a remainder of 266.
Put 7 as the next digit of the answer. 
Result so far: 597.0
The remainder is 266 after subtracting 2471 from 2737.
Append the next digit (3) from the dividend to 266 and continue with: 2663 / 353

Moving on to step 7:
353 can be fit into 2663 7 times, resulting in a remainder of 192.
Record the quotient 7 as the next digit in the result. 
Result so far: 5977.0
Subtract 2471 from 2663 to get 192.
Grab the next digit (5) from the dividend, add it to 192, then carry on: 1925 / 353

Going ahead to step 8:
1925 divided by 353 is 5 with a remainder of 160.
Record the quotient 5 as the next digit in the result. 
Result so far: 59775.0
The remainder is 160 after subtracting 1765 from 1925.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Step 9:
If we divide 1600 by 353, we get 4 and a remainder of 188.
Write down 4 as next digit of the result. 
Result so far: 59775.4
The remainder is 188 after subtracting 1412 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Let's proceed to step 10:
353 goes into 1880 5 times with a remainder of 115.
The next digit of our result is 5. 
Result so far: 59775.45
The remainder is 115 after subtracting 1765 from 1880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Step 11:
If we divide 1150 by 353, we get 3 and a remainder of 91.
Write down 3 as next digit of the result. 
Result so far: 59775.453
The remainder is 91 after subtracting 1059 from 1150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Advancing to step 12:
If we divide 910 by 353, we get 2 and a remainder of 204.
Use 2 as the next digit of our solution. 
Result so far: 59775.4532
The remainder is 204 after subtracting 706 from 910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Let's proceed to step 13:
When dividing 2040 by 353, we get 5 with a remainder of 275.
Put 5 as the next digit of the answer. 
Result so far: 59775.45325
The remainder is 275 after subtracting 1765 from 2040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Going ahead to step 14:
353 goes into 2750 7 times with a remainder of 279.
Write down 7 as next digit of the result. 
Result so far: 59775.453257
Subtracting 2471 from 2750 leaves us with 279.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2790, and continue the process.

Step 15:
353 can be fit into 2790 7 times, resulting in a remainder of 319.
The number 7 becomes the next digit in our result. 
Result so far: 59775.4532577
Subtracting 2471 from 2790 leaves us with 319.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3190, and continue the process.

The quotient of the division is 59775.4532577, and the remainder is 3.19e-06.
