70248426 divided by 680 
The aim is to understand the frequency of 680 in 70248426.

On to step 1:
If we divide 7 by 680, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (0) from the dividend to 7 and continue with: 70 / 680

Going ahead to step 2:
If we divide 70 by 680, we get 0 and a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 70 and we're left with 70.
Take the next digit (2) from the dividend and append it to 70, then repeat: 702 / 680

Step 3:
680 goes into 702 1 times with a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 680 from 702 and we're left with 22.
Append the next digit (4) from the dividend to 22 and continue with: 224 / 680

Moving on to step 4:
680 goes into 224 0 times with a remainder of 224.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we take 0 away from 224, we end up with 224.
Bring next digit (8) of the dividend behind the 224 and repeat the process: 2248 / 680

On to step 5:
The number 680 fits into 2248 3 times, leaving a remainder of 208.
Put 3 as the next digit of the answer. 
Result so far: 103.0
Deduct 2040 from 2248 and we're left with 208.
Grab the next digit (4) from the dividend, add it to 208, then carry on: 2084 / 680

Advancing to step 6:
680 can be fit into 2084 3 times, resulting in a remainder of 44.
Record the quotient 3 as the next digit in the result. 
Result so far: 1033.0
The remainder is 44 after subtracting 2040 from 2084.
Grab the next digit (2) from the dividend, add it to 44, then carry on: 442 / 680

Advancing to step 7:
When dividing 442 by 680, we get 0 with a remainder of 442.
Put 0 as the next digit of the answer. 
Result so far: 10330.0
The remainder is 442 after subtracting 0 from 442.
Grab the next digit (6) from the dividend, add it to 442, then carry on: 4426 / 680

Step 8:
If we divide 4426 by 680, we get 6 and a remainder of 346.
The next digit of our result is 6. 
Result so far: 103306.0
Subtract 4080 from 4426 to get 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

Step 9:
680 can be fit into 3460 5 times, resulting in a remainder of 60.
Record the quotient 5 as the next digit in the result. 
Result so far: 103306.5
If we subtract 3400 from 3460, we get 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 10:
The number 680 fits into 600 0 times, leaving a remainder of 600.
Record the quotient 0 as the next digit in the result. 
Result so far: 103306.5
The remainder is 600 after subtracting 0 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Going ahead to step 11:
680 goes into 6000 8 times with a remainder of 560.
Record the quotient 8 as the next digit in the result. 
Result so far: 103306.508
Subtract 5440 from 6000 to get 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

On to step 12:
If we divide 5600 by 680, we get 8 and a remainder of 160.
The next digit of our result is 8. 
Result so far: 103306.5088
The remainder is 160 after subtracting 5440 from 5600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

The quotient of the division is 103306.5088, and the remainder is 0.0016.
