51921060 divided by 745 
We want to figure out the number of times 51921060 can be divided by 745.

Going ahead to step 1:
745 can be fit into 5 0 times, resulting in a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 745

Moving on to step 2:
745 can be fit into 51 0 times, resulting in a remainder of 51.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 51 to get 51.
Take the next digit (9) from the dividend and append it to 51, then repeat: 519 / 745

On to step 3:
When dividing 519 by 745, we get 0 with a remainder of 519.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 519, we get 519.
Fetch the next digit (2) from the dividend, attach it to 519 and continue: 5192 / 745

Going ahead to step 4:
5192 divided by 745 is 6 with a remainder of 722.
The next digit of our result is 6. 
Result so far: 6.0
Deduct 4470 from 5192 and we're left with 722.
Grab the next digit (1) from the dividend, add it to 722, then carry on: 7221 / 745

Let's proceed to step 5:
When dividing 7221 by 745, we get 9 with a remainder of 516.
The number 9 becomes the next digit in our result. 
Result so far: 69.0
If we subtract 6705 from 7221, we get 516.
Include the next digit (0) from the dividend after 516, then repeat: 5160 / 745

Let's proceed to step 6:
The number 745 fits into 5160 6 times, leaving a remainder of 690.
The next digit of our result is 6. 
Result so far: 696.0
If we subtract 4470 from 5160, we get 690.
Fetch the next digit (6) from the dividend, attach it to 690 and continue: 6906 / 745

On to step 7:
745 can be fit into 6906 9 times, resulting in a remainder of 201.
The number 9 becomes the next digit in our result. 
Result so far: 6969.0
If we take 6705 away from 6906, we end up with 201.
Grab the next digit (0) from the dividend, add it to 201, then carry on: 2010 / 745

Advancing to step 8:
The number 745 fits into 2010 2 times, leaving a remainder of 520.
The number 2 becomes the next digit in our result. 
Result so far: 69692.0
If we subtract 1490 from 2010, we get 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Let's proceed to step 9:
When dividing 5200 by 745, we get 6 with a remainder of 730.
Write down 6 as next digit of the result. 
Result so far: 69692.6
If we take 4470 away from 5200, we end up with 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7300, and continue the process.

On to step 10:
7300 divided by 745 is 9 with a remainder of 595.
Record the quotient 9 as the next digit in the result. 
Result so far: 69692.69
The remainder is 595 after subtracting 6705 from 7300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5950, and continue the process.

On to step 11:
When dividing 5950 by 745, we get 7 with a remainder of 735.
Write down 7 as next digit of the result. 
Result so far: 69692.697
The remainder is 735 after subtracting 5215 from 5950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7350, and continue the process.

Let's proceed to step 12:
745 goes into 7350 9 times with a remainder of 645.
The number 9 becomes the next digit in our result. 
Result so far: 69692.6979
Subtract 6705 from 7350 to get 645.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6450, and continue the process.

On to step 13:
745 can be fit into 6450 8 times, resulting in a remainder of 490.
Write down 8 as next digit of the result. 
Result so far: 69692.69798
Deduct 5960 from 6450 and we're left with 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Let's proceed to step 14:
745 can be fit into 4900 6 times, resulting in a remainder of 430.
Record the quotient 6 as the next digit in the result. 
Result so far: 69692.697986
Subtract 4470 from 4900 to get 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

On to step 15:
745 can be fit into 4300 5 times, resulting in a remainder of 575.
Put 5 as the next digit of the answer. 
Result so far: 69692.6979865
If we take 3725 away from 4300, we end up with 575.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5750, and continue the process.

Going ahead to step 16:
If we divide 5750 by 745, we get 7 and a remainder of 535.
Write down 7 as next digit of the result. 
Result so far: 69692.69798657
Deduct 5215 from 5750 and we're left with 535.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5350, and continue the process.

The final outcome is 69692.69798657, with a leftover of 5.35e-07.
